I told my boss I would not work unpaid in terms of attending outside of work meetings and training. He has now arranged an appraisal and I feel sick with anxiety. Is this his way of firing me? I do everything else well, never off sick, no major incidents, highly qualified and experienced and am good at what I do but I have a bad feeling he has come to berate me and fire me. I feel so bullied by the company and they never listen.
