Union of Construction, Allied Trades and Technicians

The Union of Construction, Allied Trades and Technicians (UCATT) is a British and Irish trade union which represents, as of December 2012, 84,377 workers in construction and allied trades.

UCATT was formed in 1971 following the merger of the Amalgamated Union of Building Trade Workers (AUBTW), the Association of Building Technicians and the Amalgamated Society of Woodworkers and Decorators, which had itself been founded the previous year from a merger of the Amalgamated Society of Woodworkers (ASW) and the Amalgamated Society of Painters and Decorators (ASPD)
