Ours is a big company, but my team is small and consists of 4 members. I joined here 6 months before, and my boss was my lunch mate before he became my manager (since I was in other team). Now he is my manager. The problem is he started ignoring me and taunting/insulting me in front of all, which is hindering my self-confidence.
I have left lunch group and started eating alone. Will this affect my job, since I know he will be blamed indirectly for departure of me from that group?
