As for the German perspective: There are several big time companies around here who had to institute regulations so that you can't even access your work emails beyond your office hours (BMW, Telekom). So the employees themselves would check them more and the company had to limit that.

Granted, I don't know how much the "Betriebsrat" was prompting that, but I doubt that people themselves are that much different, despite German Gemütlichkeit.

I found that both IT workers and MBAs are IT/MBA first, nationals second.
