Signed by Franklin D. Roosevelt on June 25, 1938, the Fair Labor Standards Act set a national minimum wage (initially 25 cents an hour), a maximum workweek of 44 hours (soon reduced to 40) with time-and-a-half overtime, and strict limits on 'oppressive child labor.' The Supreme Court upheld the Act in United States v. Darby (1941), overruling Hammer v. Dagenhart. The FLSA still governs the American workday. Congress has periodically raised the minimum wage and extended coverage; its overtime and child-labor rules remain central battlegrounds of employment law.
