The first personnel departments were created to stop workers from organizing.
The earliest corporate personnel departments appeared in the United States between 1900 and 1920, a period of intense labor unrest. NCR (National Cash Register Company) established one of the first recorded personnel departments around 1901, followed by companies like B.F. Goodrich and International Harvester.1
The departments emerged partly from the welfare capitalism movement, in which corporations provided housing, recreational facilities, and other benefits to employees. The explicit goal was to reduce turnover and, in many cases, to undercut the appeal of labor unions.2
Frederick Winslow Taylor's scientific management principles, published in 1911, accelerated the formalization of hiring and evaluation. If work could be broken into standardized tasks, it followed that workers should be selected and measured against standardized criteria. Personnel departments became the administrative machinery for this logic.3
The transformation from "personnel" to "human resources" occurred in the 1970s and 1980s. The new name reflected a conceptual shift, from administering employees to managing them as strategic assets. The term "human resources" itself had appeared in academic management literature by the 1960s, and companies began renaming their departments over the following two decades.4
The U.S. Civil Rights Act of 1964 and the Equal Employment Opportunity Commission guidelines of 1966 and 1970 added a legal compliance function that expanded HR departments significantly.5 By 2023, the Society for Human Resource Management reported over 300,000 members worldwide. The department created to manage workers now manages the entire lifecycle of employment, from onboarding to exit interview.
