The union was founded in 1946 with the merger of the Mental Hospital and Institutional Workers Union and the Hospital and Welfare Services Union, with the aim of having one union to represent workers in the National Health Service on its formation.
In 1993, COHSE merged with two other trade unions - NUPE (the National Union of Public Employees) and NALGO (the National Association of Local Government Officers) - to form UNISON, the largest public sector trade union in the UK.
