Yeah Germany is kinda weird.
We had the voluntary option for employees to use their own phones. Until in Germany their "workers council" decided that as a company we should supply the tools for the job, and they wanted it to be blocked for employees to use their own phones. This caused so much anger with the employees because even though we already give everybody a company phone, a lot of people hate carrying 2 of them and simply stuff the work sim into their second slot and enroll it in the company MDM. On Android in particular the work environment is completely separate.
But for some reason this "workers council" is a total deity there. Even though the employees are represented the people on there are these overzealous crusaders that want everything done their way. We have this phenomenon in Holland too (called "Ondernemingsraad") but they don't tend to heavily-handed force things like this.
But whatever, the Germans can have their rules and regulations, I'm just glad I don't live there. I hate being told what I can and can't do.
