I think the 3 people higher up who dislike me and side with my boss are all trying to make things uncomfortable for me at work so that I leave.

It seems they have teamed up against me. This is what it feels and looks like. I am getting the cold shoulder at different times from all 3 of them.

And yesterday my boss randomly and for no particular reason pulled together a multi-team bagels and coffee meeting. I've never seen this done in this company, there was no collective goal or purpose so it was silly, at the end of which one of the 3 of them wrote public praise for my boss that goes into my boss's HR folder. This woman, her friend, publicly wrote what a "beautiful soul" my boss is, and how "it is such "a joy" to work with her, then wrote "love you!" - it was a jab and direct rub right in my face!

Wth? What is wrong with people? What do I do?

I seriously think that the 3 of them teamed up and collectively decided to make me feel uncomfortable so that I leave - all because I went to HR about my boss.

Other than leaving or going to HR, what do I do?
