Hi I’ve handed in my resignation notice as I can no longer work with undermining toxic boss. He has made my life hell for months with put downs constant criticism no progression opportunities left out of activities outside work etc. I have a new job only problem is it’s contractor side and my current role is the client so chance of working again with him in the future. Hr advised me to raise a grievance before I leave in November but not sure what to do. I’m also being ignored and it’s pretty lonely and few weeks off before i officially leave. I’m the only female in the team not that it should matter but I’m disappointed and it’s a pretty big company I’m in.
