Working with a lot of different personalities, there is always going to be some kind of problem that arises. How I've tried to handle it in the past is to take that particular person aside and try to communicate with them as much as I can about the issues that we're dealing with at the time, see if there's a compromise, and if the issues keep pursuing, especially if they're more drastic, then maybe I would take it to management. But I always try to be direct with the person that I might be experiencing some issues with.
