The American Federation of Labor and Congress of Industrial Organizations (AFLâCIO) is a national trade union center and the largest federation of unions in the United States. It is made up of fifty-six national and international unions, together representing more than 12 million active and retired workers.
Both the CIO and its rival the AFL grew rapidly during the Great Depression. The rivalry for dominance was bitter and sometimes violent. The CIO (Congress for Industrial Organization) was founded on November 9, 1935, by eight international unions belonging to the American Federation of Labor. In its statement of purpose, the CIO said it had formed to encourage the AFL to organize workers in mass production industries along industrial union lines.
