Every few years a new study comes out showing that US employees use less PTO than their stated policy allows, and every few years HR teams talk about why. The usual explanations (overwork, guilt, understaffing) are all part of the picture, but the bigger factor is policy design. A policy that explicitly encourages use, has a visible utilization metric, and is backed by managers who actually take time off themselves produces very different behavior than a policy that technically permits time off but quietly signals that using it is risky. The words on the page matter less than the signals around them.
Accrual vs. Unlimited PTO, and Why Both Still Exist Accrual policies grant a fixed number of PTO hours per pay period, typically based on tenure. A new hire might accrue 3.08 hours per biweekly pay period (80 hours per year), while a 10-year veteran accrues 6.15 hours per period (160 hours per year). The accrued balance is an earned asset owed to the employee at any given moment.
Unlimited or flexible PTO removes the accrual entirely. Employees take time off as needed with manager approval, no bank to track. The employer saves on accrued liability; employees lose a payout at termination but often gain more flexibility. Studies show that unlimited PTO users often take fewer days off than peers on accrual plans, not more.
The State Payout Rules That Matter Most Several states treat accrued PTO as earned wages that must be paid out at termination, regardless of company policy. California is the most prominent. Colorado, Montana, Nebraska, and Illinois also have strong payout requirements. Some states ban "use it or lose it" policies that forfeit accrued hours at year-end.
Unlimited PTO arrangements largely sidestep the payout obligation because there's no accrued balance to pay. That's one of the real financial motivations behind adoption, even if it's not the one employers usually lead with.
Do Employers Have to Offer PTO? Federal law does not require paid vacation or paid personal time. State laws have shifted meaningfully, with many states now requiring paid sick leave specifically (separate from broader PTO) and a handful requiring paid family leave. A pure PTO bank that combines vacation and sick time must meet the state sick-leave minimum floor to be compliant.
Designing a PTO Policy That Employees Actually Use The policy language is the smallest part of the design. What matters more is manager behavior, team culture around coverage, and the signals leadership sends about using time off. When executives visibly take vacation, when managers have explicit handoff plans, and when teams have enough cross-coverage that one person's absence doesn't create a fire, utilization goes up.
Track PTO utilization as a management metric. If one team's utilization is consistently lower than the company average, the policy isn't the problem. The manager or the workload is. Review BLS data on paid vacation benefits to benchmark your accrual schedule against the broader market.
Running a Paid Time Off Program That Supports Retention Tie PTO policy to your broader benefits strategy and your employee handbook language. Specify how PTO interacts with paid holidays, sick leave, parental leave, and disability. The intersections are where most payroll and compliance mistakes live.
Revisit the policy annually. State laws change quickly. The 2026 landscape includes significant new paid leave rules in several states, and a policy last reviewed in 2022 is almost certainly out of step somewhere. Review the DOL's state paid sick leave tracker whenever your workforce expands into a new state.
