Dealing with passive aggressive
Don't buy into the reasons the passive agressive may offer. Never try to guess why he is doing what he's doing, judge the behavior itself. Send a clear message that you will not tolerate his behaviour. Be specific about what it is to dislike, expect or want from him. Set personal limits for yourself. Make direct requests and accept straight answers only. Avoid generalities. Focus on the issue, cincentrate on the here and now. Don't mention past issues or speculate about the future. Keep focus on the behavior he needs to change. Anticipate that he wants to win regardless. Be prepared to protect yourself. Have supporters and own the numbers, facts.
