The Electrical Trades Union was a trade union representing electrical technicians and engineers in Ireland.
Initially, it was named the Electrical Trades Union (Dublin), but became the Electrical Trades Union (Ireland) in 1925.
[2] The union was initially very small, with only 240 members in 1930, but grew to 1,000 in 1940.
From the 1960s onwards, the union began accepting workers in a wide variety of jobs only loosely connecting with electrical matters, and this enabled it to expand its membership above 6,000 by 1970.
In 1974, the British Electrical Trades Union became part of the Electrical, Electronic, Telecommunications and Plumbing Union, and the Irish union took the opportunity to drop the disambiguator from its own name, officially becoming the "Electrical Trades Union" for this first time.
