When resolving problems among team members, I typically meet with them individually and collectively to collect facts and propose a compromise. I typically try to maintain an objective perspective and not involve myself in the conflict itself. However, on one occasion I felt compelled to take sides in a disagreement and directly reprimand a subordinate for breaking with company protocol and ignoring project guidelines. The subordinate quit the next day. If faced with a similar situation today, I'd try to find a less confrontational solution.
