I have been told many times to keep everything "rated G, or your going on the carpet." You have to be 21 to work at my un-named place of work. If I said half the things that the Hound gets away with on GOT, I would get wrote up, and after to many of those, canned.
You have NO First Amendment rights at your workplace. If an imagine on a computer screen offends ANYONE, for ANY reason they can show you the door.
What he is asking is well within reason, IMO.
As for me, I can't even use Google at work, so screw me, POI?
