If you are one of several people who perceive the same basic problems, perhaps it would make sense to get together with them privately for a strategy session. The group of you should compare problems, compare how your boss responds, and see if you can figure out what patterns apply to the boss's behavior. At the same time, you should examine your own behavior patterns to try to determine what may trigger the boss's unfavorable response. Your next step should be to consider whether there are things you need to find out to develop a clearer understanding of what makes your boss tick. It may be that if you put your heads together and figure out what you know and what you don't know, it will help you develop the kinds of questions you need to ask to create a more successful strategy.

It is important for you and your colleagues to develop and maintain a mutually consistent strategy.
