I'm getting a new boss (for several unknown reasons I was not promoted to this position, although I have the skills and experience), who does not have any specific experience in the field which he will be responsible for.
My boss's boss told me that I have to support my boss and teach him all the skills and tasks, including all the know-how, which I built and have done over years, so he can be my boss. I have already had several discussions with my boss's boss, but without any resolution or any insight.
Now, I do not want to give all my experience and know-how away and teach him from scratch all the things. First, because I think it is not my job to do this and I do not have the resources and secondly a boss in my view has to bring at least a little bit of a glimpse of the subject for which he is responsible for.
What do you think is a good strategy to handle it to not beeing rude or denying, also regarding daily business and subject specific questions from his side?
