I.P.E.U Geraghty & CO CHICAGO
This button represents Chicago's Beer Drivers and Helpers Union, Local 744. The local was part of the Teamsters. There was fierce competition between the Teamsters and the United Brewery Workers (UBW) about who would represent the beer drivers. In 1913, the American Federation of Labor awarded jurisdiction to UBW. In 1933, after the repeal of Prohibition, the Teamsters gained jurisdiction. The UBW and the Teamsters merged in 1973, putting an end to the competition.
