United Glass and Ceramics Workers of North America

The United Glass and Ceramics Workers of North America (UGCWNA) was a labor union representing workers in several related industries in the United States and Canada.The union was chartered by the American Federation of Labor (AFL) on August 7, 1934, as the Federation of Flat Glass Workers of America.It aligned with the Congress of Industrial Organizations (CIO), and as a result, was suspended from the AFL in 1936, and expelled in 1938.Its scope was broadened, and in 1940, it was renamed as the Federation of Glass, Ceramic and Silica Sand Workers of America.[3] On September 1, 1982, it merged into the Aluminum, Brick and Clay Workers' International Union, which renamed itself as the Aluminum, Brick and Glass Workers' International Union.
