That is the question, if I do not have a legal ground. Should I contact the company and report his behavior during my employment and after. There is more details that I am choosing not to mention.
I feel he violated the boss and employee relationship. He overstep the lines, I asked hime repeated for him to leave me a alone and let me do my job. Instead, I had no choice to quiet my job. Also, when I tried to take another job in the company he ran interference. I could not do anything without his promission.
So, I quiet and he still called me at my new job for over one year. You tell me that sounds normal?
