The American Federation of Labor and Congress of Industrial Organizations (AFL–CIO) is an umbrella federation made up of 56 unions representing 12.5 million working men and women in the US. It was formed in 1955 when the AFL and the CIO - previously bitter rivals - merged.
"Solidarity Forever" is a union anthem written by Ralph Chaplin in 1915 and sung to the tune of "John Brown's Body". Originally written for the Industrial Workers of the World (IWW), other union movements, including the AFL-CIO, have adopted the song.
