A trade union is an organised association of workers in a trade, group of trades or profession whose main purpose is to protect and further their rights and interests. This may be done by collective bargaining, for example in respect of terms and conditions of employment, through the adoption of collective agreements with employers and by giving advice and support to trade union members, for example in respect of disciplinary matters.

In order to enjoy all the legal rights available to trade unions, a trade union must be “independent” i.e. be free of employer control and be recognised by the relevant employer. There is an official list and schedule of trade unions maintained by the government’s Certification Officer.

To be able to organise a strike, trade unions must meet a number of conditions. Further information about strikes can be found here.
