"The Building and Construction Union (German: IG Bau-Steine-Erden, IG BSE) was a trade union representing building workers in Germany.
The union was founded in October 1949, at a conference in Karlsruhe. It was the last of the sixteen affiliates of the German Trade Union Confederation (DGB) to be established, because of difference of opinion between the communist-influenced construction union in the British occupation zone, members of the South Baden and Bavarian union who would have preferred to remain independent, and restrictions on unions in the French occupation zone.
All the initial executive members of the union had been prominent trade unionists in Weimar Germany, and as a result they had the highest average age of executive members of any DGB affiliate." - (en.wikipedia.org 31.01.2020)
