There is a senior manager at work that I always had the impression was a lovely guy. I’ve had a few interactions with him now and realise he’s a total prat when he thinks he can get away with it. One to one he often gets aggressive in tone, raises his voice and makes passive aggressive comments. He seems to set out with the intent of belittling me in every interaction. I’ve had four interactions with his this month and all four he’s been awful. Thankfully I have only very few times I need to deal with him, but every time it’s the same. I’m quite thick skinned but having had to deal with him today at it again, it has gotten to me. It’s completely uncalled for. As an example, I’ll make a simple request of him to answer a question regarding a project having checked this information isn’t available elsewhere. He will, instead of answering me say “all the information is in file x, you should have checked there before contacting me.” I’ll double check to make sure I’m not going insane but it’s not there, I’ll explain this and he will go nuclear on me and be like “I don’t know why we need so many people to check the same information over and over again!” - then someone else will step in and explain again what I’ve explained and ask and he’ll grudgingly produce the answer after more huffing and puffing. It leaves me feeling so shit. Would I be unreasonable to complain about this behaviour to my boss?
