The entire CIO group was expelled from the AFL in November 1938 and became the Congress of Industrial Organizations (CIO), with Lewis as the first president. The growth of the CIO was phenomenal in steel, rubber, meat, autos, glass and electrical equipment. In early 1937, his CIO affiliates won collective-bargaining contracts with two of the most powerful anti-union corporations, General Motors and United States Steel. General Motors surrendered as a result of the great Flint Sit-Down Strike, during which Lewis negotiated with company executives, Governor Frank Murphy of Michigan, and President Roosevelt. U.S. Steel conceded without a strike, as Lewis secretly negotiated an agreement with Myron Taylor, chairman of U.S. Steel.
