I am an assistant manager and was just informed an employee in my department has been talking about me saying I did not train her well when she’s still training and it hasn’t been a week, should I leave it alone or bring it to my department managers attention. I am also fairly new but I don’t know if this is something to nip in the butt or to just leave it be for now? It doesn’t hurt my feelings since I have come from many management positions before but we all get along in the department and I don’t want it causing problems and drama for any of the other workers
