Social firm is the British term for a work integration social enterprise (WISE), a business created to employ people who have a disability or are otherwise disadvantaged in the labour market. Its commercial and production activities are undertaken in the context of a social mission, with profits going back into the company to further its goals. A significant number of the employees of social firms will be people with a disability or disadvantage, including psychiatric disabilities. The firms grew out of disillusionment with mainstream businesses, and the failure to recognise or enable everyone's potential. All workers are paid a market-rate wage or salary that is appropriate to the work. All employees are intended to have the same employment opportunities, rights and obligations.
The original social firms were established well before the term came into use in 1980s. Firms in Europe started to prosper and employ increasing numbers of people with a disability. Schemes, and coordinating organisations, became more established and numerous in the 1990
