The Little Steel strike was a 1937 labor strike by the Congress of Industrial Organizations (CIO) and its branch the Steel Workers Organizing Committee (SWOC), against a number of smaller steel producing companies, principally Republic Steel, Inland Steel, and Youngstown Sheet and Tube Company. The strike affected a total of thirty different mills belonging to the three companies, which employed 80,000 workers. The strike, which was one of the most violent labor disputes of the 1930s, ended without the strikers achieving their principal goal, recognition by the companies of the union as the bargaining agent for the workers.
