Human resource management (HRM) is the practice of recruiting, hiring, deploying and managing an organization’s employees. HRM is often referred to simply as human resources (HR). A company or organization’s HR department is usually responsible for creating, putting into effect and overseeing policies governing workers and the relationship of the organization with its employees. The term human resources was first used in the early 1900s, and then more widely in the 1960s, to describe the people who work for the organization, in aggregate.
