The GMB

The GMBis a general trade union in the United Kingdom which has more than 600,000 members. Its members work in nearly all industrial sectors, in retail, security, schools, distribution, the utilities, social care, the National Health Service (NHS), ambulance service and local government.

Structural history

GMB originates from a series of mergers, beginning when the National Amalgamated Union of Labour (NAUL), National Union of General Workers (NUGW) and the Municipal Employees Association (MEA) in 1924 joined into a new union, named the National Union of General and Municipal Workers (NUGMW). Although the new union was one of the largest in the country it grew relatively slowly over the following decades; this changed in the 1970s when David Basnett created new sections for staff, and hotel and catering workers, and changed the union's name to the General and Municipal Workers' Union (GMWU) in 1974.

In 1982, following a merger with the Amalgamated Society of Boilermakers, Shipwrights, Blacksmiths and Structural Workers (ASBSBSW), the union was renamed the General, Municipal, Boilermakers' and Allied Trade Union (GMBATU). This was sometimes shortened to "GMB", which in 1987 became the official name of the union. For several years following the highly contested merger boilermaker members retained a distinct identity in GMB's Craft Section.

The union has absorbed the following smaller unions:

In 1992, the GMB for the first time allocated all of its members to one of eight industrial sections: clothing and textiles; commercial services; construction, furniture and allied; energy and utilities; engineering; food and leisure; process; and public services.

The GMB's sections were rationalised in 2006, with the union since then consisting of GMB Commercial Services, GMB Manufacturing, and GMB Public Services.
