This one guy I work with is the biggest pain in the ass I ever encountered in my professional career as an I.T. Engineer. This guy is a certified workaholic in his 40s’, is not married, has no kids, and definitely has no social life of any kind. He can work 12-14 hour days straight and has been known to sleep in the office at times. But, that is not what bugs me about him. This guy is nosy and needs to ask me every 5 minutes what I am working on and has a bad habit of putting every single phone conversation on speakerphone, annoying not only me but everyone else in my immediate vicinity. I could tell him to piss off, but since he is in cahoots with the I.T. Director, it will only backfire in my face and make me look like the bad guy. Also, this guy has a habit of tinkering with things and screwing them up, yet is very good at pointing fingers at others and avoiding being blamed. He is good at taking credit for the work of others, but loves to make others, me being one of them, fix the problems he introduces into the system due to his carelessness. I have considered approaching HR about this guy, but as I stated previously, I fear this will backfire against me and result in my termination, not his. This guy is not my manager, yet he feels he has the right to dictate to me what I do and how I do it, and is quite arrogant about it as well. I see that my only option would be to leave this company to get as far away from this guy because bringing up this issue will only hurt me. Has anyone ever encountered such a situation? How would you deal with this guy? He is seriously affecting my ability to do my job and is becoming a major source of stress and frustration for me.
