I am giving my 2 weeks’ notice at my current employer. The person who would have become my new boss at current employer is a very toxic person and has tried to remove me from all the projects I was getting great feedback on by global department heads. She also tried to immediately remove me from firmwide committees. My original boss announced his retirement only a couple months ago and the person who would become my new boss is trying to get a promotion this year (she hasn’t been considered for one in 20 years) and has seen me and my success as a threat though I’m 2 levels junior to her.
Though my employer is a great place, I’m worried about people telling the person who would have become my new boss of my new employer and then her trying to ruin things for me at my new employer too. Is it ok for me to not disclose my new employer to anyone at my old employer? I don’t want to harm my relationships with my colleagues with whom I have become very close either.
