Missouri Labor Laws 2026: A Complete Guide for HR & Employer Compliance

Accurate as of May 7, 2026. This guide is informational and not legal advice. For specific situations, consult licensed Missouri employment counsel.

Missouri's employment law framework runs on a federal-default base for wage and hour rules, layered with several state statutes that pull hard in their own direction. The state minimum wage rose to $15.00 on January 1, 2026 under Proposition A. The Missouri Human Rights Act covers employers as small as six workers. The state has the unusual Service Letter Statute at RSMo 290.140 that requires written reasons for separation on demand. And after a stretch of voter-driven labor activism, the 2025 General Assembly used HB 567 to repeal Proposition A's paid sick time mandate before it could take meaningful root.

2025 reshaped the compliance calendar in Missouri. HB 567 was signed on July 10, 2025 and took effect August 28, 2025, ending the earned paid sick time entitlement that voters had approved only nine months earlier. The same bill struck the consumer-price-index annual minimum wage adjustments that Proposition A had built in for 2027 and beyond. The $15 minimum wage stayed. Local governments remain blocked from setting higher rates by HB 1194's 2017 preemption rule. And the federal Pregnant Workers Fairness Act now does most of the work that a Missouri-specific pregnancy accommodation law would otherwise do.

This guide walks through every Missouri employment rule that an HR or compliance team needs to operate cleanly in 2026: minimum wage and overtime, the post-Prop A sick leave landscape, MHRA discrimination rules, the Whistleblower Protection Act, hiring and background check posture, final pay and service letters, workers' compensation, E-Verify obligations, non-compete enforceability, and the smaller leave categories that quietly trip up handbooks. Missouri HR teams that want a single platform to track investigations, document decisions, and centralize employee complaints often pair these rules with an employee relations platform built for the documentation burden the MHRA imposes.

The 2026 Missouri Employment Law Updates HR Teams Should Know First

Missouri's 2025 legislative session was unusually consequential because it undid a voter-approved law in the same calendar year voters approved it. The headline items HR teams should know:

• Minimum wage at $15.00 (RSMo 290.502): The rate took effect January 1, 2026 under the surviving portion of Proposition A. Tipped employees must earn at least 50 percent of that rate as a base wage, plus tips that bring them to $15.00.
• Earned paid sick time repealed (HB 567): The accrual mandate ran from May 1, 2025 to August 28, 2025. After that date employers may continue to offer paid sick time voluntarily, but the state no longer requires it.
• CPI-linked annual increases struck: HB 567 removed Proposition A's automatic annual adjustments to the minimum wage that would have begun in 2027. Future raises require legislative or voter action.
• MHRA enforcement architecture stable: The Missouri Commission on Human Rights continues to handle charges. The 2017 SB 43 reforms (motivating-factor standard, damage caps, no individual liability) remain in force.
• No state pregnancy accommodation statute: Missouri remains among states without an explicit state-level pregnancy accommodation law. Employers default to the federal Pregnant Workers Fairness Act and the MHRA's pregnancy discrimination protections.
• No state paid family or medical leave program: Multiple bills (SB 548, SB 1069) have been introduced in recent sessions and have not advanced. Federal FMLA remains the only mandated leave for most Missouri employers.

Each of these is unpacked below. The pace of change matters: an employer that wrote a paid sick time policy in spring 2025 to comply with Proposition A may now need to audit whether voluntary continuation creates contract or estoppel exposure under the new rules.

Missouri Minimum Wage and Overtime Rules

The 2026 minimum wage is $15.00 per hour for most non-exempt employees, set by RSMo 290.502 as amended by Proposition A. Missouri's framework is set by the state Department of Labor and Industrial Relations and tracks the federal Fair Labor Standards Act for overtime calculation, with one important state-specific feature: the state rate now exceeds the federal floor by $7.75, the largest gap in Missouri's history.

What is Missouri's minimum wage in 2026?

Missouri's minimum wage is $15.00 per hour, effective January 1, 2026. The rate applies to private-sector employers covered by RSMo Chapter 290. Government employers are not bound by the state minimum wage statute and can pay at the federal rate.

Tipped employees must be paid a cash wage of at least 50 percent of the minimum wage. At $15.00, that is $7.50 per hour in cash, with tips making up the remainder. If tips do not bring the employee to $15.00 in any pay period, the employer must make up the difference. Missouri does not allow a tip pool that includes back-of-house staff who do not customarily receive tips.

Several categories of employees are exempt from the state minimum wage:

• Retail or service businesses with annual gross income under $500,000.
• Bona fide executive, administrative, or professional employees who meet the federal salary threshold of $684 per week.
• Outside salespeople who regularly perform sales duties away from the employer's premises.
• Casual babysitters and certain agricultural workers.
• Family members employed by an immediate family member's business.

Does Missouri have its own overtime rules?

Missouri does not impose state-specific daily overtime obligations. The federal FLSA controls: non-exempt employees must receive 1.5 times their regular rate for hours worked over 40 in a workweek. Missouri does not require overtime for hours over 8 in a day.

The state's exempt-salary threshold mirrors federal FLSA. As of 2026, an employee classified as exempt under the executive, administrative, or professional duties tests must earn at least $684 per week ($35,568 annually) on a salary basis. The 2024 federal increase to $844/week was vacated by a Texas district court in November 2024, so the $684 floor remains the operative number until the U.S. Department of Labor issues a new rule.

Misclassification remains the most common Missouri wage and hour exposure. The state Department of Labor's Division of Labor Standards investigates worker complaints and can recover unpaid overtime. Employees may also pursue private FLSA actions in federal court. Documentation of duties and salary basis is the only defense that holds up in litigation, which is why HR teams pair classification audits with centralized case management for any complaint that touches pay accuracy.

How does Missouri handle local minimum wages?

Missouri preempts city and county minimum wages above the state rate. HB 1194, signed in 2017, blocked St. Louis and Kansas City from enforcing local minimum wage ordinances that had been moving forward at the time. The St. Louis ordinance had survived a Missouri Supreme Court challenge in February 2017, only to be nullified by HB 1194 later that year.

As a practical matter, the only Missouri rate is the state rate. Employers cannot point to a local floor for any worksite in the state. They also cannot use a higher local rate to justify a different exempt-status test. The state rate is the starting line for both.

Paid Sick Leave in Missouri After the Proposition A Repeal

Missouri does not currently mandate paid sick leave. The state did, briefly, between May 1 and August 28, 2025, under Proposition A. HB 567 repealed that mandate. Employers may continue to offer paid sick time voluntarily, but they are no longer required to do so.

What was the Proposition A paid sick leave law?

Proposition A, passed by Missouri voters on November 5, 2024, required employers with 15 or more employees to provide one hour of paid sick leave for every 30 hours worked, up to 56 hours per year. Employers with fewer than 15 employees had to provide up to 40 hours per year. The accrual obligation began May 1, 2025.

During the accrual period, employees could use sick leave for personal illness, family member illness, public health emergencies, and absences related to domestic or sexual violence. The law required employer notice to employees and prohibited retaliation against workers who used the leave.

What does HB 567 change?

HB 567 was signed by Governor Mike Kehoe on July 10, 2025 and became effective August 28, 2025. The bill repealed Proposition A's earned paid sick time provisions in their entirety. As of August 28, 2025, no Missouri employer is required by state law to provide paid sick leave.

The bill also repealed the Proposition A provisions that would have automatically adjusted the minimum wage for inflation starting in 2027. The minimum wage rises to $15.00 on January 1, 2026 as scheduled, but no automatic adjustments will follow.

What should employers do with their paid sick leave policies now?

Three paths are common, each with risk:

• Continue the policy unchanged. Many employers wrote handbooks in spring 2025 promising paid sick time. Continuing the policy maintains employee trust but creates contract and estoppel exposure if the company ever wants to scale back.
• Sunset the program with notice. Provide written notice that paid sick time accrual ends on a specific date. Allow accrued time to be used during a wind-down window. Document the change in handbook revisions and require employee acknowledgment.
• Convert to PTO. Roll any accrued paid sick balances into general paid time off. This simplifies administration and reduces the perception of a takeaway, but PTO comes with its own final-pay obligations under Missouri practice.

Whatever path an employer takes, document the change before it takes effect. Retroactive policy changes to leave benefits are the kind of action that draws plaintiffs' attorneys, particularly in a state where wage statements are not heavily regulated and disputes hinge on what employees were told.

Missouri Human Rights Act: Discrimination, Harassment, and Retaliation

The Missouri Human Rights Act at RSMo Chapter 213 is the state's primary employment civil rights statute. It applies to employers with six or more employees for 20 or more weeks in the current or prior calendar year. The Missouri Commission on Human Rights enforces it.

What classes does the MHRA protect?

The MHRA prohibits discrimination, harassment, and retaliation based on:

• Race
• Color
• Religion
• National origin
• Ancestry
• Sex (including pregnancy and pregnancy-related conditions)
• Age (40 to 69)
• Disability

Sexual orientation and gender identity are not enumerated under Missouri state law. Federal Title VII protections (under Bostock v. Clayton County) and various local ordinances cover those categories. Missouri's age range stops at 69, narrower than the federal ADEA, which protects workers age 40 and over without an upper bound.

How did SB 43 change the MHRA?

Senate Bill 43, signed by Governor Eric Greitens on June 30, 2017, restructured the MHRA in three significant ways:

• Higher proof standard. For claims accruing on or after August 28, 2017, plaintiffs must show that a protected characteristic was the "motivating factor" in an adverse employment decision, not merely a "contributing factor." This brought Missouri closer to the federal Title VII standard.
• No individual liability. Supervisors and coworkers cannot be sued individually under the MHRA. The statute redefined "employer" to exclude individual employees, ending a long line of cases that allowed plaintiffs to sue managers personally.
• Damage caps. SB 43 imposed compensatory and punitive damage caps that scale with employer size, ranging from $50,000 for employers with 6 to 100 employees up to $500,000 for employers with more than 500 employees.

The motivating-factor standard is the change with the most operational impact. Documentation of legitimate business reasons for any adverse action now matters more than it did under the old contributing-factor regime.

How long do employees have to file an MHRA charge?

An employee must file a charge of discrimination with the Missouri Commission on Human Rights within 180 days of the alleged discriminatory act. This is the same deadline that applied before SB 43. The shorter Missouri window contrasts with the 300 days available for federal EEOC charges in states with work-sharing agreements.

After the MCHR investigates, it issues either a no-probable-cause finding or a notice of right to sue. Once the right-to-sue notice is issued, the employee has 90 days to file a civil action in state court.

Does Missouri require harassment training?

No. Missouri does not mandate sexual harassment prevention training for private-sector employers. The MCHR encourages training as best practice, and the EEOC's broader guidance on preventing harassment provides a recommended framework. Employers in industries with high harassment risk often run training annually anyway, partly to support an affirmative defense if a claim is filed.

For employers with operations in multiple states, the most cost-effective approach is to apply the strictest training requirement (typically California, Connecticut, Illinois, or New York) across the workforce. That keeps content consistent and prepares Missouri-based managers to handle complaints under the MHRA's documentation expectations.

Missouri Whistleblower Protection Act

RSMo 285.575, the Whistleblower's Protection Act, codifies Missouri's protections for employees who report unlawful conduct. The Act applies to employers with six or more employees and provides a private right of action for retaliation.

What conduct does the Act protect?

The Act protects an employee who, in good faith:

• Reports an unlawful act by the employer or by another employee to a supervisor or external authority.
• Refuses to carry out a directive that would violate state or federal law, rule, or regulation.
• Reports serious misconduct by the employer that violates a clear mandate of public policy.

A 2022 Missouri appellate decision held that reporting unlawful conduct of a coworker to a supervisor is protected activity under the Act, clarifying earlier ambiguity about whether internal reports about non-supervisors qualified.

What remedies are available?

A protected person aggrieved by retaliation may recover actual damages including back pay, lost benefits, and reinstatement where appropriate. Punitive damages are not available under the Act. However, if the protected person proves by clear and convincing evidence that the employer's conduct was outrageous because of evil motive or reckless indifference, the court may double the actual damages awarded.

The Act displaced earlier common-law wrongful discharge claims in Missouri. After SB 43 codified the at-will doctrine and channeled retaliation claims into RSMo 285.575, plaintiffs generally cannot bring stand-alone public-policy wrongful discharge actions outside the Act's structure.

Most retaliation exposure in Missouri starts with an internal complaint that was not properly documented. HR teams that centralize whistleblower reports alongside investigation notes have a defensible record if a retaliation claim follows months later.

Hiring Rules: Background Checks, Salary History, and Onboarding

Missouri's hiring framework is lighter than coastal states. There is no statewide ban-the-box law for private employers, no salary history ban, and no statewide pay transparency requirement. The federal Fair Credit Reporting Act controls third-party background check disclosures and authorizations.

Does Missouri have a ban-the-box law?

Not for private employers. Missouri removed the criminal history question from state government job applications by executive order in 2016, but the rule applies only to executive-branch state agencies. Local ordinances apply in some Missouri cities for public employees but generally do not reach private employers.

Kansas City passed a private-employer ban-the-box ordinance in 2018, restricting initial inquiries about criminal history. Employers should verify current local rules before relying on city-specific compliance assumptions.

Can Missouri employers ask about salary history?

Yes. Missouri does not prohibit employers from asking job applicants about prior salaries. There is no statewide pay transparency law requiring disclosure of pay ranges in job postings. Employers operating in multiple states should still apply the strictest salary-history rules they face elsewhere to avoid inconsistent practices that could become Title VII or MHRA evidence.

Are background checks regulated?

The federal Fair Credit Reporting Act controls. Missouri does not impose extra disclosure or authorization requirements beyond FCRA. Employers must:

• Provide a clear, stand-alone written disclosure before obtaining a consumer report.
• Obtain written authorization from the applicant.
• Provide pre-adverse action notice with a copy of the report and a summary of FCRA rights before taking adverse action based on the report.
• Provide adverse action notice with the consumer reporting agency's contact information after taking action.

Missouri employers using third-party background screening should treat FCRA compliance as the floor and pair it with documented individualized assessment for any adverse decision driven by criminal history. The EEOC's 2012 guidance on consideration of arrest and conviction records remains the relevant standard for Title VII purposes.

Missouri E-Verify Requirements

Missouri's E-Verify rule applies to public employers and certain public contractors, not the general private-sector workforce. The statutory framework lives in RSMo Chapter 285 and was enacted through HB 1549 in 2008.

Who has to use E-Verify in Missouri?

Missouri requires E-Verify enrollment for:

• All public employers, meaning state agencies, political subdivisions, and public institutions.
• Public contractors with state or political subdivision contracts or grants exceeding $5,000.
• Recipients of state-administered or subsidized tax credits, tax abatements, or loans.

Private employers without state contracts are not required to use E-Verify under Missouri law, though many do voluntarily because federal contracts and several federal funding streams require it.

What are the consequences of non-compliance?

A public contractor found to have knowingly violated Missouri's E-Verify rule faces:

• 14-day suspension of business license or other public benefits for first violations.
• 3-year debarment from state contracts for public contractor violations.
• Withholding of up to 25 percent of contract amounts due.
• Permanent debarment for repeat violations, with up to 25 percent of amounts due withheld again.

Private employers should verify E-Verify obligations against the specific funding sources they touch. Federal contractor coverage under Executive Order 12989 is independent of Missouri state rules and applies to most federal prime contracts and many subcontracts.

Final Pay, Pay Statements, and the Service Letter Statute

Missouri's wage payment rules are tighter than its hiring rules. Final pay timing on involuntary termination is among the strictest in the country, and the Service Letter Statute is unusual nationally.

When is a Missouri employee's final paycheck due?

An employee discharged by a Missouri employer is entitled to all wages earned and unpaid on the day of discharge under RSMo 290.110. The statute applies to involuntary terminations. There is no comparable state deadline for resignations; final pay for a voluntary quit can wait until the next regular pay date.

If the employer fails to pay on the day of discharge, the employee can demand payment by certified mail with return receipt. The employer then has seven days to pay. If the employer still does not pay, the employee can recover additional wages at the same daily rate for up to 60 days as a penalty, plus attorney's fees in some cases. RSMo 290.110 does not require employers to pay accrued unused vacation unless the employer's policy so provides.

What is the Missouri Service Letter Statute?

RSMo 290.140, the Service Letter Statute, requires Missouri employers with seven or more employees to provide a written letter explaining the nature and character of an employee's services and the true cause of separation, on request. The statute applies when:

• The employee was employed for at least 90 days.
• The employee makes the request in writing by certified mail with specific reference to the statute.
• The request is made within one year of separation.

The employer has 45 days to respond. The letter must include duration of service, nature and character of work performed, and the true reason for discharge or voluntary departure. It must be signed by a superintendent or manager.

An employer that fails to issue the letter is liable for compensatory damages, and in some cases punitive damages, though punitive damages cannot be based on the content of the letter itself. The Service Letter Statute is a frequent vehicle for plaintiffs' attorneys to surface separation reasoning before filing an MHRA charge. Employers should prepare draft service letter language at the time of any contested termination, not when the request arrives.

What pay statement information is required?

Missouri does not impose a state-specific itemized pay stub statute on private employers. Employers must comply with federal recordkeeping rules under the FLSA, which require accurate records of hours worked, regular and overtime rates, deductions, and gross and net pay. Missouri's Department of Labor recommends written pay statements as a best practice.

Pay frequency is governed by RSMo 290.080, which requires payment at least twice per month (semi-monthly) for most employees. Employers may pay weekly or biweekly. Manufacturing employees and a handful of other categories have specific rules.

Workers' Compensation in Missouri

Missouri's workers' compensation framework lives in RSMo Chapter 287. The Division of Workers' Compensation in the Department of Labor and Industrial Relations administers the system.

Which Missouri employers must carry workers' compensation insurance?

Most employers with five or more employees must carry workers' compensation insurance. The threshold drops to one or more employees for any employer in the construction industry. Independent contractors are not counted toward the employee threshold, though Missouri courts apply a multi-factor test to evaluate true independent contractor status.

Employers can satisfy the obligation in two ways:

• Insurance through a carrier authorized by the Missouri Department of Insurance.
• Self-insurance through the Division's self-insurance program, which requires demonstrating financial stability.

What are an employer's reporting obligations?

An employer must:

• Post notice of workers' compensation coverage in a prominent workplace location.
• Report any injury requiring medical attention beyond first aid to its insurance carrier within five days of receiving notice.
• Report fatalities to the Division of Workers' Compensation within 30 days.
• Provide medical care to the injured employee through the employer's chosen medical provider.

What happens if an employer fails to carry coverage?

An employer without required coverage may be sued by an injured worker in civil court for the full benefits available under the Workers' Compensation Law, plus possible additional damages. The Division of Workers' Compensation can also impose penalties and refer cases for prosecution. Civil exposure typically dwarfs the savings from going uninsured.

Is there a Missouri retaliation rule for workers' comp claims?

Yes. Section 287.780 prohibits an employer from discharging or discriminating against an employee because the employee exercised any right under the Workers' Compensation Law. The remedy is a private civil action for actual damages and, in some cases, punitive damages.

Workers' comp retaliation claims are commonly bundled with MHRA disability claims when an injured worker is later terminated. HR teams that maintain consistent documentation across leave, accommodation, and discipline records have the best defense. Many use investigation workflows to keep that documentation discoverable years after the fact.

Smaller Leave Categories Under Missouri Law

Missouri does not have a state family medical leave equivalent. Federal FMLA covers eligible employees of covered employers (50 or more employees within 75 miles, employee with 12 months and 1,250 hours). Beyond FMLA, Missouri has several small leave categories that should appear in any compliant handbook.

How does Missouri handle voting leave?

Missouri requires employers to provide three hours of paid time off to vote on election day. The leave is unavailable if the employee has three continuous hours of off-duty time while polls are open. Employees must request leave before election day, and the employer can specify when during the workday the leave occurs.

An employer that violates voting leave provisions can be charged with a misdemeanor under Missouri election law. The 3-hour paid block makes Missouri one of the more generous voting leave states, though enforcement actions are rare.

What is required for jury duty?

RSMo 494.460 protects employees responding to jury summons. An employer cannot terminate, discipline, threaten, or take adverse action against an employee on account of receipt of or response to a jury summons. Employees cannot be required to use vacation, personal, or sick time to cover jury service.

Missouri does not require employers to pay for jury service. An employee discharged in violation of the statute has 90 days to bring a civil action for lost wages, other damages, and reinstatement.

Does Missouri require military leave?

Missouri's military leave protections track the federal Uniformed Services Employment and Reemployment Rights Act (USERRA). State-employed members of the Missouri National Guard receive up to 15 days of paid military leave per year under RSMo 41.946. Private-sector military leave obligations follow USERRA: job restoration, accumulation of seniority, and continuation of health coverage during qualified service.

Are there protections for victims of domestic violence?

RSMo 285.625, Missouri's Victims' Economic Safety and Security Act (VESSA), provides unpaid leave for victims of domestic or sexual violence at employers with 20 or more employees. Eligible employees can take up to two weeks of leave per 12-month period for medical attention, counseling, court proceedings, or to seek protective orders.

The leave is unpaid. Employees must give 48 hours' advance notice when practicable. Employers must keep documentation confidential and cannot retaliate against an employee for taking VESSA leave.

Does Missouri provide bereavement leave?

No. Missouri does not require private employers to provide paid or unpaid bereavement leave. State employees have access to bereavement leave under state HR rules, but private-sector workers depend on employer policy. Many Missouri employers offer 3 to 5 days of paid bereavement leave for immediate family, particularly for retention reasons in tight labor markets.

Non-Compete and Restrictive Covenant Posture

Missouri non-compete law remains a common-law system. There is no comprehensive non-compete statute. RSMo 431.202 governs limited categories of restrictive covenants among business owners. The general framework comes from a long line of Missouri court decisions.

When are non-competes enforceable in Missouri?

Missouri courts will enforce a non-compete that is reasonable in scope and necessary to protect a legitimate business interest. Courts evaluate:

• Duration: a one-year post-employment restriction is presumed reasonable. Two years is the upper bound that most courts treat as the limit. Beyond two years, enforceability becomes difficult.
• Geographic scope: must be tied to the employer's actual market.
• Activity scope: must restrict only competition that could harm a legitimate business interest, not all competition.
• Protectable interest: the agreement must protect trade secrets or customer relationships, not merely shield the employer from competition.

What is the Missouri "blue pencil" rule?

Missouri courts may modify (blue pencil) overbroad non-competes rather than refusing to enforce them. The court can narrow duration, geography, or activity scope to a reasonable level. This contrasts with states like Wisconsin and Virginia, where overbroad non-competes are simply unenforceable.

The blue pencil rule means employers can draft aggressively without forfeiting enforcement entirely. Plaintiffs' attorneys argue that the rule encourages overreach. The practical impact: Missouri employers should still draft to a reasonable scope, because litigation costs to reach a blue-pencilled outcome easily exceed the value of the broader restriction.

Does the FTC's vacated non-compete ban apply in Missouri?

No. The FTC's nationwide non-compete ban was set aside by the U.S. District Court for the Northern District of Texas in August 2024 before its scheduled effective date. The FTC has not pursued further appellate review at the federal level, so Missouri non-compete enforceability continues to be governed by state common law.

Independent Contractor Classification in Missouri

Missouri has no state-specific ABC test. The Department of Labor and Industrial Relations and Missouri courts apply the common-law right-to-control test for most employment law purposes, with some statute-specific variations.

How does Missouri define an independent contractor?

A worker is generally an independent contractor in Missouri when:

• The hiring entity does not control the means and manner of how the work is performed.
• The worker has economic independence through their own tools, business expenses, and customer base.
• The work is project-based or outcome-based rather than continuous employment.
• The contract reflects an arms-length business relationship with appropriate documentation.

Misclassification exposure in Missouri runs through several agencies: the Division of Employment Security for unemployment insurance, the Division of Workers' Compensation for workers' comp coverage, the IRS for federal tax treatment, and the U.S. Department of Labor for FLSA wage and hour purposes.

What's the risk of misclassification?

A misclassified contractor that is later determined to be an employee triggers liability for:

• Back wages including overtime under FLSA.
• Unpaid unemployment insurance taxes with penalties and interest.
• Workers' compensation coverage retroactively, plus medical benefits for any injuries during the misclassified period.
• FICA taxes the employer should have paid.
• Benefit plan exposure if the contractor would have been eligible for employer-sponsored plans.

Missouri does not have the aggressive private-attorney enforcement rights that California's PAGA creates, so misclassification claims usually come from individual disputes, agency audits, or bankruptcy/successor-liability situations rather than statewide class actions.

Pay Equity and Pay Transparency

Missouri does not have a state Equal Pay Act distinct from federal protections. The Equal Pay Act of 1963 and the MHRA's sex discrimination protections together cover pay disparity claims. The state has no pay data reporting requirement and no salary range disclosure mandate.

What about local pay transparency rules?

Kansas City and St. Louis do not have local pay range disclosure ordinances for private employers. Employers operating in Missouri alongside states like Colorado, California, New York, and Washington should expect to publish pay ranges anyway because remote and hybrid postings often trigger out-of-state requirements regardless of where the employer is headquartered.

Is there a Missouri equal pay statute?

RSMo 290.410 prohibits sex-based wage discrimination by employers with seven or more employees. The statute is older than the federal Equal Pay Act and is rarely the lead claim in modern litigation, but it provides a state-court venue and shorter MCHR exhaustion path that some plaintiffs prefer.

Workplace Safety and OSHA Coverage

Missouri operates under federal OSHA jurisdiction. The state does not run its own OSHA-approved state plan for private-sector workplaces. Federal OSHA's Kansas City Area Office covers the western half of the state and the St. Louis Area Office covers the eastern half.

What injury reporting is required?

Federal OSHA rules apply directly:

• Report a work-related fatality within 8 hours.
• Report a work-related inpatient hospitalization, amputation, or loss of an eye within 24 hours.
• Maintain OSHA 300 log for all employers with more than 10 employees, except in partially exempt industries.
• Post OSHA 300A summary February 1 through April 30 each year.

For workers' compensation purposes, separate Missouri Division of Workers' Compensation reporting applies on the timelines described above (5 days for medical-treatment injuries, 30 days for fatalities).

Mass Layoffs and Plant Closings

Missouri has no state mini-WARN Act. The federal Worker Adjustment and Retraining Notification Act controls mass layoff and plant closing notice obligations.

When does federal WARN apply?

Federal WARN applies to employers with 100 or more employees. It requires 60 days' advance written notice to affected employees, the chief elected official of the local government, and the state dislocated worker unit when:

• A plant closing involves a permanent or temporary shutdown of a single site of employment, resulting in employment loss for 50 or more employees during any 30-day period.
• A mass layoff involves at least 50 employees and at least 33 percent of the workforce, or 500 or more employees regardless of percentage.

Missouri's Department of Higher Education and Workforce Development serves as the state's dislocated worker unit and receives WARN notices. Employers should also notify the Missouri Office of Workforce Development for rapid response coordination, though this is administrative rather than statutory.

Failure to provide WARN notice carries 60 days of back pay and benefits per affected employee, plus civil penalties of up to $500 per day for failing to notify the local government.

Recordkeeping Obligations

Missouri's recordkeeping rules are largely federal. The state Department of Labor recommends:

• Wage and hour records for at least three years (matches federal FLSA).
• Workers' compensation records through the duration of any open claim plus relevant statute of limitations.
• I-9 records for three years after hire or one year after termination, whichever is longer.
• Personnel files for the duration of employment plus a reasonable period afterward (no specific Missouri rule).
• EEO-1 reporting for federal contractors and employers with 100+ employees under federal rules.

Does Missouri require personnel file access?

Missouri has no statutory right for private-sector employees to access their personnel files. State government employees have access rights under separate civil service rules. Employers operating in multiple states often grant Missouri employees the same access available in stricter states (California, Illinois) for administrative consistency.

Right-to-Work Status and Union Posture

Missouri is not a right-to-work state. In 2017, the General Assembly passed and Governor Greitens signed a right-to-work law, but voters rejected the law in an August 2018 referendum (Missouri Proposition A) by a margin of 67.5 percent to 32.5 percent. The repeal was Missouri voters' first time reversing an enacted right-to-work law via referendum.

For employers, the practical effect is that union security clauses (requiring dues payment as a condition of employment) remain enforceable in Missouri. Compare this to neighboring Kansas, Iowa, and Nebraska, where right-to-work statutes prohibit union security agreements. Missouri's posture also affects federal labor law strategy: organizing campaigns and collective bargaining negotiations operate under the National Labor Relations Act with the full range of agency-shop provisions available.

Drug and Alcohol Testing

Missouri permits employer drug testing within reasonable limits. There is no comprehensive state drug testing statute for private employers. The framework varies by industry and use case.

What about medical and recreational marijuana?

Missouri voters approved Amendment 3 in November 2022, legalizing recreational marijuana for adults 21 and older. The amendment includes employment-related provisions:

• Employers may prohibit marijuana use on the premises during work hours.
• Employers may take adverse action against employees who use, possess, or are impaired by marijuana on the job.
• Employers cannot discriminate against medical marijuana patients solely for their status, but may still discipline for actual on-the-job impairment or use.
• Safety-sensitive positions may have stricter rules where required by federal law (DOT-regulated drivers, federal contractors).

A positive drug test alone does not establish on-the-job impairment for marijuana, since THC metabolites can remain in the system for weeks after use. Missouri employers should pair testing with documented observation of impairment and clear policy notice. The amendment does not require employers to allow medical marijuana use on premises or to accommodate impairment that creates safety risk.

Employee Privacy in the Workplace

Missouri's privacy framework is mostly federal. State-specific rules exist in narrow areas.

Can Missouri employers monitor employee communications?

Yes, with notice. Missouri is a one-party consent state for recording communications under RSMo 542.402. An employer that records calls or monitors emails through a system the employer is a party to does not violate state wiretap law. Best practice is to disclose monitoring in policy and at the point of communication where practical.

Are social media credentials protected?

Missouri does not prohibit employers from requesting social media login information. A handful of bills have been introduced in past sessions but none has passed. Employers asking for social media access should consider the federal Stored Communications Act and the EEOC's guidance on social media in hiring before pursuing the practice.

Missouri State Agencies for HR Teams

Knowing where claims, audits, and notices come from speeds response time. The agencies that touch Missouri employment law in 2026:

• Missouri Department of Labor and Industrial Relations: umbrella agency for the Division of Labor Standards (wage and hour), Division of Workers' Compensation, Division of Employment Security (unemployment insurance), and the Missouri Commission on Human Rights.
• Missouri Commission on Human Rights: investigates MHRA charges and issues right-to-sue notices. The 180-day filing deadline runs to this agency.
• Office of the Missouri Attorney General: takes enforcement action in some employment matters.
• U.S. Department of Labor (Kansas City and St. Louis Regional Offices): federal FLSA, FMLA, USERRA, and OSHA enforcement.
• U.S. Equal Employment Opportunity Commission (St. Louis District Office): Title VII, ADA, ADEA, GINA, PWFA, and Equal Pay Act enforcement.
• National Labor Relations Board (Region 14, St. Louis): federal labor law jurisdiction over private-sector union activity.
• Missouri Office of Workforce Development: serves as the state's dislocated worker unit for federal WARN notices.

How long do MCHR investigations take?

The Missouri Commission on Human Rights typically investigates charges over 6 to 18 months. The agency can find probable cause and refer the case for civil action, find no probable cause, or close the case for procedural reasons. After issuing a right-to-sue letter, the complainant has 90 days to file a civil action.

During the investigation, the MCHR will request a position statement from the employer and may interview witnesses. The position statement is the employer's first formal opportunity to lay out its legitimate, non-discriminatory reasons for the challenged action. Position statements that conflict with later deposition testimony are routinely cited in cross-examination, which is why coordinated documentation across HR, legal, and operations matters from the moment a complaint surfaces.

How AllVoices Helps Missouri HR Teams

AllVoices is an employee relations platform that gives HR teams a single place to receive, document, and resolve employee concerns across the full Missouri compliance picture. The platform is particularly relevant for Missouri operations because of three patterns the state's law creates.

The MHRA's motivating-factor standard rewards documentation. When a plaintiff argues that a protected characteristic was a motivating factor in an adverse action, the employer's contemporaneous record of legitimate business reasons is the deciding evidence. AllVoices keeps complaint intake, investigation notes, and outcome documentation in one timeline that can be exported in defensible form. Vera AI, the platform's investigation assistant, helps HR draft consistent investigation reports that speak the same language across the team.

The Whistleblower Protection Act creates retaliation exposure for any internal complaint that touches unlawful conduct. Routing complaints through a tracked intake channel rather than informal email or hallway conversations makes downstream retaliation claims defensible. Anonymous reporting through the AllVoices hotline gives employees a safe way to raise concerns under RSMo 285.575 without fear of supervisor reprisal.

The Service Letter Statute and the day-of-discharge final pay rule both reward fast, well-documented separations. AllVoices integrates with major HRIS platforms (Workday, Rippling, Paylocity, BambooHR) so termination data flows through the same case-management workflow that documented the underlying performance or conduct issues. When a service letter request arrives weeks later, the record is already there. Teams that want to see the platform in action can request a walkthrough that focuses on Missouri-specific use cases.

The platform also addresses leave administration handoffs (FMLA, VESSA, military leave), which become contested when termination follows soon after a leave. Missouri does not have a state PFML program, but employers with workers in nearby states need a single workflow that handles different leave codes without losing the audit trail.

Frequently Asked Questions

What is the Missouri minimum wage in 2026?

The Missouri minimum wage in 2026 is $15.00 per hour, effective January 1, 2026 under RSMo 290.502. Tipped employees must receive a cash wage of at least $7.50 per hour, with tips bringing total compensation to $15.00. The rate applies to private employers; the state government and federal employers remain on the federal $7.25 floor.

Does Missouri require paid sick leave in 2026?

No. HB 567 repealed Proposition A's earned paid sick time provisions effective August 28, 2025. Missouri employers may continue to offer paid sick leave voluntarily, but state law no longer requires it. Federal FMLA still applies to covered employers for unpaid family and medical leave.

When is a final paycheck due in Missouri?

For involuntary termination, the final paycheck is due on the day of discharge under RSMo 290.110. If the employer does not pay on that day, the employee can demand payment by certified mail. The employer has seven days to comply. Failure to comply triggers up to 60 days of additional wages as a penalty. For voluntary resignations, final pay can wait until the next regular pay date.

How many employees does the MHRA cover?

The Missouri Human Rights Act applies to employers with six or more employees for 20 or more weeks in the current or prior calendar year. The lower threshold compared to federal Title VII (15 employees) means many small Missouri employers face state discrimination claims even though they are exempt from federal Title VII.

Are non-competes enforceable in Missouri?

Yes, when reasonable in duration, geography, and scope, and when designed to protect a legitimate business interest such as trade secrets or customer relationships. One-year post-employment durations are presumed reasonable. Beyond two years, enforceability becomes difficult. Missouri courts can blue-pencil overbroad agreements rather than voiding them entirely.

Does Missouri require harassment training?

No. Missouri does not mandate sexual harassment prevention training for private employers. The MHRA prohibits harassment, and the Missouri Commission on Human Rights and EEOC strongly encourage training as best practice and as part of an affirmative defense, but no state statute requires it.

Is Missouri a right-to-work state?

No. Missouri voters rejected a right-to-work law in an August 2018 referendum by 67.5 percent to 32.5 percent. Union security clauses remain enforceable in Missouri, distinguishing it from neighboring Kansas, Iowa, and Nebraska.

What is the Missouri Service Letter Statute?

RSMo 290.140 requires Missouri employers with seven or more employees to provide a written letter explaining the nature of an employee's services and the true reason for separation, on request. The employee must have worked at least 90 days, must request the letter in writing by certified mail referencing the statute, and must do so within one year of separation. The employer has 45 days to respond. Failure to comply can result in compensatory and punitive damages.

The Bottom Line

Missouri's 2026 employment law landscape is a study in how quickly state law can change. Voters approved a $15 minimum wage and paid sick time in November 2024. Eight months later, the legislature kept the minimum wage and repealed the sick time. The MHRA has been more stable since the 2017 SB 43 reforms, and the framework around the Service Letter Statute, Whistleblower Protection Act, and final pay rule has held its shape for years. The pace of voter-driven and legislature-driven change means HR teams should expect continued legislative volatility through the 2026 session.

The 2026 priorities for Missouri HR teams:

• By January 1, 2026: verify all wage rates reflect $15.00 minimum and $7.50 tipped cash wage; update payroll systems and pay statement templates.
• By February 1, 2026: document any voluntary continuation of paid sick time policies in handbooks; require employee acknowledgment of changes.
• By March 31, 2026: audit independent contractor classifications against current Missouri Division of Employment Security standards; document the right-to-control analysis for each role.
• By April 30, 2026: review service letter procedures and pre-draft language for any pending separations; train HR managers on the 45-day response window.
• Throughout 2026: maintain consistent documentation under the MHRA's motivating-factor standard for every adverse action; keep investigation notes timestamped and centralized.
• Ongoing: monitor the 2026 legislative session for changes to MHRA, Whistleblower Protection Act, and any new paid leave proposals.

Missouri rewards employers that document early and consistently. Teams that want a single source of truth for complaints, investigations, and separations can see how AllVoices handles employee relations from intake through resolution.
