Amalgamated Society of Boilermakers, Shipwrights, Blacksmiths and Structural Workers
|Merged into||National Union of General and Municipal Workers|
The union was founded in 1852, when the Scottish Society of Boilermakers, the United Friendly Boilermakers' Society and the Amicable and Provident Society of Journeymen Boilermakers of Great Britain merged to form the United Society of Boilermakers and Iron and Steel Shipbuilders. In 1952, it renamed itself as the United Society of Boilermakers, Shipbuilders and Structural Workers, then in 1963 it merged with the Associated Blacksmiths, Forge and Smithy Workers' Society and the Shipconstructors and Shipwrights' Association, adopting its final name.
In 1982, the union joined the National Union of General and Municipal Workers, which renamed itself as the General, Municipal, Boilermakers and Allied Trades Union.
