I work in an office, general admin duties.... pretty boring really but it pays the bills and its not the most painful job in the world. Anyway I'm quite good friends with a lot of my colleagues and we do tend to socialise outside of work.
Recently one of the blokes (mid 30s) got a promotion to "team leader" which doesn't mean he's a manager just means he is trusted to be left in charge of the office and to delegate work to others.
He's had a massive power trip since his promotion and basically thinks he's king of the business. He talks to people like shit, demands them to pretty much his job for him, has a completely dark sense of humor (I also do, but I am aware who I can share my jokes with and who I cannot and I know where the line is) and he does not give a f*ck about what he says in front of people. E.g - I work with a guy who is jewish and this colleague ALWAYS makes sick jokes about the holocaust around him?!
Lately He's started spreading rumours about others in the office too, like one of the blokes I work closely with let's call him Kevin.... I am very friendly with Kevin and his OH, but this guy has started telling people that he's shagging another woman in the office because they go for lunch occasionally together! Its only a matter of time before his OH finds out and goes crazy.
He manages to do all of this on the sly without any of the bosses seeing so it's hard to capture any sort of evidence. We have all spoken as a team and decided it's time to talk to our bosses about it, but seriously, it's starting to get beyond ridiculous. AIBU reporting him? Does it make me look like a massive asshole? He makes all of us so angry and uncomfortable. At the same time I don't want him to lose his job because I know he's had a troubled past and it may lead him on a downhill slope if he gets sacked. WWYD?
