I started working at a new company recently. My coworker who sits next to me watches "adult" videos constantly throughout the day. He doesn't even try to hide it. Nobody else seems to mind, and a lot of the guys seem buddy-buddy with him.
Now, I'm not a prude or anything, but this makes me very uncomfortable. Not only are the videos particularly disturbing and graphic (not even going to explain it here), but I'm the only female in the office and feel like people allowing this is going to contribute to sexism in the office.
The other day, I asked him politely if he could not watch this at work. He gave a sort of half hearted apology, which I thought was his way of saying he'd stop. But the next day he was right back at this. I later mentioned this to my boss, who just kind of shrugged it off and told me not to worry about it.
Is it a good idea to bring this up to HR? Since he'll probably figure it was me who brought it up, is there anything I can do to avoid possible blowback from him? Normally I would just ignore these things and avoid the conflict, but this is really bothering me
Just adding an edit:
Well, I feel really stupid.
I brought this up to HR. My VP then sat me down today and explained that a major pornographic site is one of our biggest clients, and my coworker has been working on a project for them for the past year. He then asked me why I hadn't read through the new employee training materials which covered information like this.
My boss is now upset with me, especially because he told me not to worry about it. To "avoid conflict" he has moved this coworker to another cube (the only opening is in the basement). Now everybody is clearly upset with me, since they all seem to like this coworker.
