In our everyday professional life, we repeatedly experience situations which make clear the difference between male and female behaviour. For example: Before the start of a meeting, a projector must first be set up. In this situation, a man asks directly “Can somebody here fix the device?” — a woman, on the other hand, first tries to find the problem herself. And then the parties involved perceive each other very differently, which has an effect on the course of the negotiation that follows. From the woman’s point of view, the man is behaving pompously and arrogantly, whereas the man sees weakness in the woman’s concern.
