Ever since I was hired apparently I'm the kid who knows how to do shit. He wants to do a bunch of crap that has no idea how to do it properly. They are simple tasks so I wouldn't care if, at least, I was recognized for doing his bullshit little requests.
Not only am I not recognized, but the asshole also takes credit for my work. I'm working in a multinational corporation, and he avoids leaving any traces of me doing the work (no emails, no meetings, nothing.) If I want to join the meetings he gives some bullshit excuse that I'm not needed there.
I'm tired of this crap and his slimy nature by now. How do I fuck him over? Or at the very least, say no in such a way that he won't bother me again?
