A trade union is an association of workers in a particular industry or sector, designed to protect the rights, interests and working conditions of employees. Large trade unions in the UK include the TUC, Unite, Unison, the GMB and Usdaw.
Trade unions can receive recognition, or employers can derecognise trade unions. Employment laws protecting employees taking industrial action, such as taking part in strikes or picketing, are contained in the Employment Rights Act 1996 and Trade Union and Labour Relations (Consolidation) Act 1992.
