The GMB is a general trade union in the United Kingdom which has more than 560,000 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

The National Amalgamated Union of Labour (NAUL), National Union of General Workers (NUGW) and the Municipal Employees' Association (MEA) merged in 1924 to form 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.

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

GMB Credit Union

To serve its members with ethical loans and finance and helpful support, GMB launched a standalone credit union offering in 1998.

Founded as Thorne Credit Union after Will Thorne, founder of NUGW forerunner, the National Union of Gas Workers and General Labourers and one of the first Labour Members of Parliament, the credit union began life as GMB Lancashire Region Credit Union before being rolled out nationwide in 2000. Today, the credit union serves over 10,000 nationwide and growing rapidly.

The credit union is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the PRA. Ultimately, like the banks and building societies, members' savings are protected against business failure by the Financial Services Compensation Scheme.

Landmark Uber employment tribunal case

On 28 October 2016, in a landmark ruling if not overturned on appeal, the Central London Employment Tribunal ruled that Uber drivers are "workers" entitled to the minimum wage, paid holiday, sick leave and other normal worker entitlements, rather than self-employed. Two Uber drivers had brought the case to the employment tribunal with the assistance of the GMB Union on 20 July 2016, as a test case on behalf of a group of 19 drivers. As a consequence, The Pensions Regulator is considering if the ruling obliges Uber to create a workplace pension scheme. The ruling could have implications wider than just Uber, throughout the so-called gig economy. On 10 November 2017 the Employment Appeal Tribunal upheld the first tribunal's ruling. Uber indicated that it would appeal further.

The law firm Leigh Day started the legal action against Uber on behalf of 25 members of the GMB union, which initially included J. Farrar and Y. Aslam, although the two pursued this latest case with a different union, the Independent Workers' Union of Great Britain.

On 10 February 2017 a similar case involving Pimlico Plumbers was confirmed at the Court of Appeal. A worker who had suffered a heart attack was found to have been unfairly or wrongfully dismissed.

Another similar case against parcel delivery company Hermes Group, supported by the GMB through lawyers Leigh Day, had a similar outcome at an employment tribunal in Leeds on 25 June 2018. Hermes are considering an appeal. The GMB stated the ruling was likely to affect 14,500 Hermes couriers. General Secretary, Tim Roache, described it as:
