Trade union

What does it mean?

A trade union is a private, democratic organisation that brings together employees within a particular industry, trade or sector. Its main purpose is to protect members' interests vis-à-vis employers — primarily on pay, terms of employment and collective agreements.

In Denmark, trade unions often work closely with unemployment funds (a-kasser) and employer associations to negotiate collective agreements that set minimum pay and conditions for entire industries. Membership is voluntary but common — around two thirds of Danish employees belong to a union.

As a member you can get legal advice on employment contracts, help during disputes, support if you are dismissed, and access to courses and networking. Unions also engage in political advocacy for workers' rights.

Choosing a union depends on your industry: HK for commerce and office workers, IDA for engineers and IT professionals, 3F for construction and transport, and many others. Some unions offer student or graduate membership at reduced rates.
