Sheet Metal Workers International Association Local 3

The Sheet Metal Union of Omaha, Nebraska was started by a number of dedicated tradesmen in the late 1880’s.
Omaha, together with six other mid-western metal labor groups, met on January 25, 1888 in Toledo, Ohio to form the “Tin Sheet-Iron and Cornice Workers International Union.”
Omaha became Local #3 and Leo Hart from Omaha became General Vice President.
In 1897, the name was changed to “Amalgamated Sheet Metal Workers International Association”, and in 1903 to “Amalgamated Sheet Metal Workers International Alliance”, and finally in 1924 to “Sheet Metal Workers’ International Association.”
