Amalgamated Engineering and Electrical Union

The Amalgamated Engineering and Electrical Union (AEEU) was a British trade union. It merged with the MSF to form Amicus in 2001.

The history of the union can be traced back to the formation of the "Old Mechanics" of 1826, which grew into the Amalgamated Society of Engineers in 1851. Many local and regional unions joined the ASE in subsequent years and in 1920, after the acquisition of nine fresh member unions, the name of the organisation was changed to the Amalgamated Engineering Union. The AEU continued to grow and absorb smaller unions. Its largest membership growth came during the Second World War when its all-male membership voted to admit women for the first time and 100,000 joined almost immediately. However, the AEU also lost its overseas branches in Australia, New Zealand and South Africa, who became independent unions.

The AEU merged with the foundry workers union NUFW in 1967 and the draughtsmen's union DATA in 1971 to form the Amalgamated Union of Engineering Workers, AUEW. That merger was torn apart by political and industrial differences between the blue- and white-collar sections and the former DATA became Technical, Administrative and Supervisory Section, TASS before merging with the white-collar union ASTMS, led by Clive Jenkins, to form Manufacturing Science Finance, MSF.

The rest of the AUEW returned to the AEU name, absorbing the Construction Engineering Union and the small roll-turners union. The AEU became a mainstay of the moderate right in the trade union movement through the 1980s and 1990s, leading the manufacturing unions in 1989-91 in a successful push for a shorter working week, but failing to merge with a number of unions, notally the building workers union UCATT.

In 1992 the AEU finally achieved a merger with the Electrical, Electronic, Telecommunications and Plumbing Union, EETPU, after a hundred years of off and on discussions. . The new union took the name Amalgamated Engineering and Electrical Union
