Your boss is only interested in what affects work production. If your problem with a peer is a personal dislike, difference of opinion, or other non‐production related matter, they won't care…nor should they. In order to get them involved you need to demonstrate that the problem is affecting your efficiency or that of your department. Make your approach only after trying all you can to resolve the situation on your own. If your supervisor remains reluctant to get involved, even after you demonstrate the problem is influencing work, stress that you've run out of other options. If you can't get them to intervene, agree to make one final effort at solving the matter on your own, but only if they agree to intervene if you're unsuccessful. Try to insure the situation doesn't have a negative impact on your reputation. You don't want to be perceived as a whiner or rat, you just want to be able to do your job. The more you show your supervisor that your main concern is the company, not yourself, the better chance they'll help you resolve the problem.
