And quite a few companies do not work with unions for various reasons at all. THAT is also quite legal, no one is forced to join a trade association. IT generally has none since the union would be verdi and anyone with a pay grade above "roomsweeper" will not find verdi a good union. IF IT cooperates with a union it is typically one of the IGs (IGBCE mostly) for historical reasons. Only big IT that does verdi is T-Systems. And to quote a T-Systems engineer on uses for verdi: "Practice target for the 5inch gun, they are so hollow, they'll float"
Biting the hand that feeds IT
