Harlan County, KY, coal miners win affiliation with UMWA union, United States, 1973-1974
In June of 1973, workers at the Brookside coal mine in Harlan County, Kentucky voted 113-55 to replace their membership in the Southern Labor Union (SLU) and join the United Mine Workers of America (UMWA) union. The SLU was largely seen as serving the interests of the mine owners rather than the workers.
The owners of the mine, Eastover Coal Company, a subsidiary of Duke Power Company, refused to sign the new contracts, which would have established a UMWA local in Brookside.
