What Are Human Resources?
Whether you're stepping into your first corporate role or scaling a startup, understanding what human resources (HR) actually is can help you navigate your workplace more effectively.
Let’s demystify HR—no buzzwords, just facts.
The Definition: What Are Human Resources?
Human resources (HR) refers to the department within a business that is responsible for managing all aspects of the employee lifecycle—from hiring and onboarding to training, compensation, compliance, and offboarding.
More broadly, "human resources" also refers to the people who make up the workforce of an organization.
"HR is the backbone of a well-functioning business. Without HR, you're running a company with no pulse." — Dr. Susan Staley, Professor of HRM, MIT Sloan School of Management
