A new colleague was hired at my department 3 months ago. He is quite disrespectful towards other employees since the first day, acts weird, has no experience and no actual work results, but is entitled and has a huge ego. He finds (makes up) excuses to everything when someone asks him to stop doing one of his particularly annoying habits (he has several...). I have found out that all of my other colleagues find him annoying and disrespectful as well, but I'm not sure if the management knows about this.
Now normally I would just ignore such a colleague. But we have to work on an important project together, talk every day, and the management expects me to help him if he's stuck on a task. I've told my managers that I'll do it if I must, but I don't like mentoring. I didn't tell them the real reason, since the whole team was present at this meeting.
Should I approach my supervisor face-to-face, and tell him that I wouldn't like to work with the new colleague? The issue doesn't really affect my work performance right now, but it certainly stresses me out, and it greatly affects my mood and the workplace.
