A quote from Vincent from last weekend: "I can't wait until I'm out of there so I never have to see TFTB again... She's the ugliest woman I've ever seen."
For what it's worth, our cubibles and computers are arranged in such a way that passers-by cannot see the desktops. (How the hell do you think we get so much BP posting done?) Someone has to literally walk around into our spaces to see our monitors, which usually leaves plenty of time for ALT-Tabbing...
Anyway, I knew the picture was there, and it doesn't bother me personally. I did warn Vince that TFTB would be bothered by it (she's probably the second most uptight person I know, outside of my in-laws), but I left it as his choice as to whether or not he wanted to take that risk. We have no written policies in place regarding this sort of thing. Sadly, I missed the screaming and door slamming, as I was running rather late this morning... but from what I hear, it was a very inappropriate way to handle the situation. Oh, and I heard that from a neutral third party, not just from Vincent. I agree - it's their prerogative to not allow such things, but with no policy in place, there certainly was a better way to handle it.
Oh, and at my previous job, an employee did get blasted by the HR director for something similar to the Botticelli work. It wasn't that one exactly, but something similar - a classical piece of art. That HR director was the most uptight person I've met.
