The Public and Commercial Services Union (PCS) is the fifth largest trade union in the United Kingdom. Most of its members work in government departments and other public bodies although some work for private companies.
Membership and organisation
The union was founded in 1998 by the merger of the Public Services, Tax and Commerce Union (which mostly represented the executive 'managerial' grades of the Civil Service) and the Civil and Public Services Association (mostly representing the administrative grades).
The union has over 250,000 members and is the largest trade union representing civil servants in the UK. Its current general secretary is Mark Serwotka.
PCS is organised into groups that deal with different bargaining units such as Revenue and Customs, Department for Work and Pensions and Law and Justice.
