I'm pretty sure that, while they apparently party much harder on their private time, north-western Europeans appear to be much more "prude" in their work life than any other group in the world.

I also believe it's actually a part of their cultural inclusivity. It's a very stressful pressure if you're expected to go to a strip club with your colleagues after work if you're female, gay or in a relationship where such behavior would be sanctioned by the other party.

Americans and Asians apparently expect others to "fall in line" in all corporate policy matters, including this one. So as a result of globalization the corporate policy matters that one is expected to "fall in line" to have slowly become the least common denominator of all this cultures and that's the type of business chastity that is normal in today's HR rule books and everything outside is hastily sanctioned.
