I go a new job in a startup company, where it has an investor, a CEO, a technical manager (Mr X) and a bunch of other team members. They are working on their first mobile application where the technical manager failed miserably in building it (and other side projects - hence why I got hired).
They like me and it was proven how good I am in what I do. I implemented almost half the requirements in two months, which took around 3 months for Mr X to implement them (and he failed).
I am afraid that I am getting Mr X jealous because the team likes me especially the CEO and the investor since the very beginning. Last Monday we presented to the investor, he liked our work a lot. There was a plan for part of the team to go with the investor and meet other investors, and it was CEO, Mr x and the investor, but after the presentation he replaced Mr X by me to go with him (and the CEO) and meet the other investors.
There were more than one occasion, where Mr X out of no where brings up that he is the boss, especially when it is only me and him. First week's meetings they mentioned that everyone reports to the CEO. But between me and him he keeps saying that I report to him.
One occasion was when we were working remotely, and he asks "mind me doing me a favor?" I replied "no", he said "well as your boss I am telling you to do this", I replied "You asked me mind doing a favor? I said no means I don't mind ..."
Another occasion was when he brought a friend to meet the team, and he was speaking that he worked on this part, I said "and he did an excellent job", he replied by telling that friend "he is just saying that because I am his boss"
Another occasion was today when there was a happy hour close by, from 4 to 6 (where it is open to all the team to join) and I left and joined. He showed up later and I was the only team member sitting with the crowd, and said "well I am waiting for updates from my workers, and they are here hanging out!?" - where there were 0 updates expected from me.
Do I bring it up with the CEO that I am being annoyed by the fact that Mr X keeps saying that he is my boss for no reason? Do I contact the investor directly? I did not ask Mr X "what the hell are those expected updates you are talking about!?", do I ask him tomorrow and be straight forward with him to get out of my way?
