labor union

A trade union (British English) or labor union (American English), often simply referred to as a union, is an organization of workers whose purpose is to maintain or improve the conditions of their employment, such as attaining better wages and benefits, improving working conditions and safety standards, establishing complaint procedures, developing rules governing the status of employees (including rules on promotions and just-cause conditions for termination), and protecting and increasing the bargaining power of workers.

Trade unions typically fund their head office and legal team functions through regularly imposed fees called union dues. The union representatives in the workforce are usually made up of workplace volunteers who are often appointed by members through internal democratic elections. The trade union, through an elected leadership and bargaining committee, bargains with the employer on behalf of its members, known as the rank and file, and negotiates labour contracts (collective bargaining agreements) with employers.
