Managing and Working with People You Don't Like

Have you ever managed or worked with someone who is good at their job, but just rubs you the wrong way? Maybe their work style is radically different from yours, or maybe their opinions or beliefs oppose everything that you think and believe. Sometimes it's the way they express themselves or how they interact. Could be anything really, but there's just something that makes working with them unpleasant. How do you handle those situations? Do you ignore the bad stuff if they do their primary job well? If you're a manager, do you ignore the behavior that annoys co-workers, even if they complain, if that same behavior isn't extended to you? If you're the co-worker, do you contemplate murder every day in your mind, but realize there's really nothing you can do and accept that a certain level of unpleasantness is going to be part of your life?

I realize it's different if you're a manager rather than a co-worker, but I think it's a common problem. How do the rest of you deal with it?
