The International Association of Bridge, Structural, Ornamental and Reinforcing Iron Workers is a union in the United States and Canada, which represents, trains and protects primarily construction workers, as well as shipbuilding and metal fabrication employees. The union was formed on February 4, 1896 at a meeting in Pittsburgh, Pennsylvania with 16 delegates from the local unions in Boston, Massachusetts, Buffalo, New York, Chicago, Illinois, Cleveland, Ohio, New York City, New York, Detroit, Michigan, Philadelphia, Pennsylvania and Pittsburgh. Those locals, and others established later, often protected their own autonomy jealously, rejecting at least one national contract with the American Bridge Company because it would have reduced their power. The internal divisions also led the union, which had affiliated with the American Federation of Labor shortly after its formation, to disaffiliate in 1901, only to reaffiliate two years later. It was one of the charter members of the AFL's Building Trades Department, which was created in 1908. More information...
