A few jobs back, I had a coworker who was a little bit aggressive in his approach, generally was fairly unfriendly, not the most excellent person to be around, and he and I kind of butted heads on a few occasions. So what I asked to have happen is to have us both sit down with a manager present and kind of just talk things out and come to an accord, to kind of just agree to interact with each other in a very specific way, and that did help quite a bit. We both agreed to certain professional standards, and that was a very effective solution, I think, for that particular person and that particular situation.
