I live in NYC and yesterday as I was leaving my job I was pulled into the HR office without HR PERSONNEL present. I was told that after careful consideration and due to Industry changes I was being let go. I did not have much time to think of anything to ask, I was completely caught by surprise. I had NEVER been written up or counseled for my job performance, so of course I was not expecting this. I understand that there is already someone starting on Monday to fill my position.... What can I do? Can I sue ?
