Reuther's Treaty of Detroit was a five-year contract negotiated by trade union president Walter Reuther between the United Auto Workers (UAW) and General Motors in 1950. The UAW reached similar deals with the other members of the Big Three automakers, Ford Motor Company and Chrysler. The UAW agreed to a long-term contract, which protected automakers from annual strikes, and it gave up the right to bargain over some issues in exchange for extensive health, unemployment, and pension benefits; expanded vacation time; and cost-of-living adjustments to wages.
