The other nasty factor is a constant one. One of our department is a very strange man. He had a running feud with the person next to him for reasons that have never been made entirely clear to me, as she appears to be perfectly nice woman, though perhaps not willing enough to shut up and put up. I am thankful that he has now been moved, as it made me feel physically ill to hear the hatred and anger in his voice as he would wander over to people near me as soon as she left each day and launch into a half-hour tirade about all the irritating things that she had done, limited, as far as I could tell, to spending quite a lot of time emailing or on the phone. I hasten to add that the nature of our work is such that anyone slacking will be found out (as I have discovered), and their lack of work will have no impact on anything anyone else has to do, so the reason why these actions so incensed him was purely personal. He wouldn't even talk to her, or cc her in on departmental emails, and on occasion would put his fingers in his ears while she was talking to others.
He has also taken against another colleague, and delights in a little light intimidation of him while he's around, and further obsessive ranting about him when he's not. I have literally not heard him go for 3 sentences without mentioning one of these two people unless he's discussing Blondie or formula 1, which are apparently his only two interests. He is aggressive to the point of discussing how much he'd like to punch these people. He has Freddie Mercury, racing car or Debbie Harry wallpaper and screen savers. He comes in earlier than me and stays later, even when I'm arsing around on the net and stay an hour later than I have to. He gets on well with our boss. He is 35ish, and doing this crap job in which everyone else but the management is ten years younger (except the aforementioned female colleague, for whom this is a stop-gap job after having a baby). I do not understand him at all. I am glad.
