UMW Bituminous coal strike of 1977–1978

The Bituminous coal strike of 1977–1978 was a 110-day national coal strike in the United States led by the United Mine Workers of America. It began December 6, 1977, and ended on March 19, 1978. It is generally considered a successful union strike, although the contract was not beneficial to union members.

Since the 1940s, the United Mine Workers of America (UMWA) had negotiated a nationwide National Coal Wage Agreement with the Bituminous Coal Operators Association (BCOA), a group of large coal mine operators. The three-year agreements covered national bargaining issues such as wages, health and pension benefits, workplace health and safety, and work rules. Local agreements, far more limited in scope, were negotiated by each individual local affiliate of UMWA.
