"A trade union (or a labor union in the U.S.) is an association of workers forming a legal unit or legal personhood, usually called a "bargaining unit", which acts as bargaining agent and legal representative for a unit of employees in all matters of law or right arising from or in the administration of a collective agreement. Labour unions typically fund the formal organization, head office, and legal team functions of the labour union through regular fees or union dues. The delegate staff of the labour union representation in the workforce are made up of workplace volunteers who are appointed by members in democratic elections." - (en.wikipedia.org 15.12.2019)
