A trade union is an organisation of workers that seeks to protect and advance the interests of its members by negotiating with employers on pay and conditions of work. Unions may also provide legal advice, financial assistance, sickness benefits and education facilities to their members.
Individuals are free to join - or not join - a trade union. You must not treat someone unfairly for reasons relating to their union membership or non-membership.
This guide explains the employment rights of both union members and non-members who are either job applicants or already working for you.
