IG Metall

IG Metall (; IGM; German: , "Industrial Union of Metalworkers'") 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.

IG Metall and ver.di together account for around 15 percent of the German workforce, and other sectors tend to broadly follow their agreements. Provided by Wikipedia
