I happen to have a lot of insight into the situation and in this case there is also written "proof" (good feeedback, good ratings from a lot of other people etc.) Of course there is always two sides to a story.
Since I for obvious reasons can't go into a lot of details this is more of a hypotetical: Assuming there is a bad apple director what should one do?
I do generally agree with also giving directors/managers the benefit of the doubt of course and not immediately jumping to feeling targeted/mobbed.
