The Sheffield Amalgamated Union of File Trades was a trade union in the United Kingdom. It was formed in 1915 by the merger of the Machine File Forgers' Union and the Machine File Cutters' Union. In 1917, it merged with the hand-file forgers and file hardeners unions. From 1918, it admitted all workers in the file trade who were not eligible to join other unions.Sidney Pollard, A History of Labour in Sheffield It merged with the Transport and General Workers' Union in 1970.
