If this is your company and you're caught in the middle of a minefield, your best option (
short of quitting) for conflict management is to rise above it: Point out the specific behavior in question, don't personalize the issue (be objective), communicate assertively and state the facts, and
document everything that
goes on.
Early in the development of a game, a
short document is usually developed that decides what
goes on in each level in very vague terms.
