Human Resources
What is Human Resources (HR) and what does the function do?
Human Resources (HR) is the organizational function responsible for managing the employee lifecycle: recruiting, hiring, onboarding, compensating, developing, retaining, and (when necessary) terminating employees. HR also handles compliance with employment law, benefits administration, employee relations, and increasingly strategic workforce planning. The function ranges from a single generalist at small companies to specialized teams of hundreds at large enterprises, and the framing has evolved from administrative HR to strategic HR/HCM/People Operations over the past three decades.
Human Resources is the function that owns the employee experience from candidate to alumnus. The work has evolved meaningfully over the past three decades: from "Personnel" (administrative paperwork) to "HR" (broader scope including strategy) to "HCM" or "People Operations" (workforce as economic asset). The vocabulary changes more than the underlying work. The high-performing HR functions, regardless of name, do the same things well: hire the right people, develop them, pay them fairly, surface and resolve workplace concerns, and keep the compliance basics solid.
What HR Actually Does
Recruiting and talent acquisition. Onboarding. Compensation and benefits administration. Performance management. Learning and development. Employee relations and complaint investigation. Compliance (EEO, FLSA, ACA, state laws). Workforce planning and analytics.
HR Function Evolution
1970s-80s: Personnel, focused on paperwork and compliance. 1990s-2000s: HR, broader scope including strategy. 2010s-present: HCM, People Operations, strategic workforce framing. The work expanded; the underlying transactions remain.
How HR Functions Are Structured
Small (under 100): single generalist or shared founder/HR role. Mid-market (100-1,000): generalist team plus specialist for comp, recruiting. Enterprise (1,000+): centers of expertise (COEs), HR business partners, shared services, often hundreds of HR staff total. See HR business partner for the strategic role and HR generalist for the operational backbone.
Building an HR Function That Earns Strategic Credibility
The HR functions that get strategic input from leaders share three features: they get the basics right (payroll, benefits, compliance), they invest in manager capability, and they connect HR data to business outcomes. Skip strategic positioning until the operational basics work. See HRM for academic framing and HCM for software/strategy.
