A senior colleague humiliated me publicly almost two months ago. I reported this and while he denied making a comment, he "apologised" in the must insulting way possible. I have sought to have the matter dealt with formally and met with HR who tried to convince me because he said it on a work night out it didn't count(it was a work do.) I have been isolated by my line managers and HR have told me that nothing will happen at least until next month.
Advice please
