The GMB Union is one of the largest and most recognized trade unions in the United Kingdom, representing hundreds of thousands of workers across both public and private sectors. It stands for General, Municipal, Boilermakers’ Union — though today, it’s widely known simply as GMB.
Founded over a century ago, GMB Union’s primary purpose has always been clear: to protect and advance the rights of working people. From negotiating fair pay and safe conditions to offering legal help and training, GMB plays a vital role in ensuring equality and justice in workplaces.
A Brief History of GMB Union
GMB was established in 1889 during the height of industrial change in Britain. It brought together local workers and small associations that wanted a stronger, united voice.
Over time, the union grew into a national movement — advocating for fair wages, better working hours, and improved safety standards in industries like manufacturing, healthcare, retail, and transport.
Today, GMB continues that legacy by representing employees in over 600 job sectors, making it one of the UK’s most diverse and influential unions.
