I work in a busy office and one of the line managers has an awful reputation for bullying and intimidating staff, but is very good friends with the higher bosses, so therefore gets away with his actions. I do my best to keep out of his way, as he has previously made up outright lies about me (although this was a few years ago), as well as bullying other people to the point where they have been off on long term sick.
I have just found out that this man will be my new line manager. I have spoken to another line manager in confidence about that fact that I am concerned he will now target me and if given the chance, have me sacked (I think he bizarrely sees me as a threat). He was very sympathetic (as he knows what Mr Awful is like) and told me discretely on the way out of work that he has voiced my concerns to one of the higher bosses. Mr Awful is best friends with this higher boss, and I am afraid they will now discuss this between themselves in private and my life will be made hell at work. AIBU to have voiced my concerns, or should I have just 'put up and shut up'?
