The 5-year contract negotiated between the UAW and the Big Three automakers in 1950 became known as the Treaty of Detroit. The UAW agreed to a long-term contract, which protected the automakers from annual strikes, and 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. This contract shaped labor-management relations in the auto industry for decades.
