GMB Union

What GMB Union does

GMB Union is a UK-registered trade union headquartered in London, founded in the late nineteenth century (1889/1898) and operating continuously for over 130 years. It is a non-profit membership organisation representing approximately 500,000 workers across both public and private sectors in Britain, organised through more than 800 branches and a network of 10,000+ trained workplace representatives. Its core offering is membership-based collective bargaining, workplace representation, and advocacy on pay, conditions, health and safety, and equal pay, serving a horizontal cross-section of UK workers including civil service, local government, NHS, schools, social care, retail, logistics, manufacturing, energy, food and drink, security, and taxi/private hire.

The organisation's product surface is structured around a single integrated membership proposition: core union membership plus a suite of affiliated member benefits including UnionLine (legal advice helpline), GMB Credit Union (financial services), GMB Protect (insurance), GMB Dental, GMB Health Plan, GMB Learning (education and training), and GMB Extra (discounts on entertainment and travel). It runs a portfolio of national campaigns (Sick of SSP, Birmingham Pay Justice, PPE Fit For All, Workers Power The Future, ASDA Equal Pay) and participates in industry alliances such as the Confederation of Shipbuilding and Engineering Unions (CSEU).

Revenue is generated predominantly through recurring member subscription dues on a community-led go-to-market model that combines direct workplace recruiting, regional offices, and a self-serve website join flow. The union is member-owned and democratically governed, with no external investors or parent company. Gary Smith has served as General Secretary since his election in June 2021. There is no disclosed proprietary technology, AI/ML capability, or software product; GMB operates as a service organisation, with ongoing investment in digital accessibility under WCAG 2.2 Level AA.

Direct peers

• UNISON: UNISON is the UK's largest trade union, with around 1.3 million members concentrated in public services. It directly competes with GMB for members in local government, NHS, social care and the wider public sector, operating a near-identical general-union, dues-funded membership model.
• Unite the Union: Unite is one of the UK's largest general unions with a similarly horizontal footprint across both public and private sectors, including manufacturing, logistics, transport and services. Unite and GMB directly contest recognition and members across overlapping industries and workplaces.
• Public and Commercial Services Union (PCS): PCS represents civil servants and public-sector workers, a core membership category that GMB also organises. The two unions compete head-to-head for recognition in government departments and agencies, with similar collective-bargaining and campaigning models.
• Communication Workers Union (CWU): CWU represents workers across postal, telecommunications and related sectors, operating as a sector-specific union with the same dues-funded, workplace-rep-driven model as GMB. It is a like-for-like peer in how it organises, negotiates and delivers member services.
• National Education Union (NEU): NEU is the UK's largest education trade union, representing teachers and school staff. It overlaps with GMB's Schools, Academies & Education membership segment and competes for representation rights in the same education workplaces.
• Community (Union): Community is a UK general union organising across similar industries to GMB (including some manufacturing and services). GMB and Community are also formal partners via the Confederation of Shipbuilding and Engineering Unions (CSEU), making them direct peers both competitively and structurally.
• Prospect (Union): Prospect represents professionals, managers and specialists across the public and private sectors. It is a CSEU co-member alongside GMB and competes for higher-skilled member segments in overlapping industries such as engineering and defence.
• ASLEF: ASLEF is the UK train drivers' union, a sector-specific union that operates the same dues-funded, collective-bargaining, industrial-action model as GMB and competes for influence in the rail and transport sector, where GMB also organises workers.
• NASUWT: NASUWT is a UK teachers' union representing teachers and education professionals. It overlaps with GMB's education-sector membership and competes for the same school-based members using a similar dues-and-representation model.

Broad incumbents

• Royal College of Nursing (RCN): RCN is the UK's largest professional association and trade union for nursing staff, operating a membership-based model with representation and collective bargaining comparable to GMB. It is a broader incumbent in workforce representation, particularly relevant given GMB's NHS membership.
