I am sorry you are in that situation. People sometimes don't like other people for purely personal reasons and then feel the need to come up with "objective" evidence to justify their feelings.

That is really unfair but I fear it happens a lot. I had a supervisor once who was constantly looking for reasons to get me fired. Luckily he failed. Later I found out it was for personal reasons. On the other hand, I had a supervisor for whom I could do no wrong. I am so sorry that you are not getting support at work.

There are people who will be unhappy with no matter what.

Reminds me of a story of a father and son going to market on a donkey. People saw the father riding the donkey and said: How awful that the man is making the child walk while he rides the donkey.

So the man put his son on the donkey and people said: How awful that the boy is letting his poor father walk while he rides the donkey.

So both the father and son got on the donkey and people said: How awful that two people are riding on that poor little donkey.

So the father and son carried the donkey and people said: How awful that there are crazy people like them who try to carry a donkey.

Does that story make sense?
