IG Metall is the dominant metalworkers' union in Germany, making it the country's largest union as well as Europe's largest industrial union. Analysts of German labor relations consider it a major trend-setter in national bargaining.

Vereinte Dienstleistungsgewerkschaft is a German trade union based in Berlin, Germany. It was established on 19 March 2001 as the result of a merger of five individual unions and is a member of the German Trade Union Confederation (DGB). With around 1.9 million members, Verdi is the second largest German trade union after IG Metall. It currently employs around 3000 members of staff in Germany and has an annual income of approximately 454 million Euros obtained from membership subscriptions. The trade union is divided into 10 federal state districts and five divisions and is managed by a National Executive Board (Bundesvorstand) with nine members. Frank Bsirske was the chairman of Verdi from its founding in 2001 until September 2019, when Frank Werneke was elected.
