I have had an admin job for the last 7 years and I used to like it but not anymore. I don't like the office environment, and I can't stand the attitude of many of my co-workers. I work with both men and women and I have to say that it's the women who appear to be the cause of many of the problems. There is always a hell of a lot of whispering and bitching between the girls which I hate and do my best not to get dragged into.
No-one there seems to get along like we used to, actually now that I think about it, it's not actually my job that I hate, I think I just need to work with different (much nicer) people!
