From 1900-1920, pay was primarily based on piecework and cash compensation with little government regulation. From 1920-1930, skill-based pay emerged and the government intervened through New Deal programs. During 1940-1950, wages were frozen to control inflation during World War II while fringe benefits increased. Over the following decades, equal pay acts and other legislation were passed while organizations shifted to merit and market-based pay structures tied to job analysis and performance.
