I too work in a call center, and I believe it has got to be the sickest form of work environment there is~! Dealing with the calls, day in and day out is bad enough..... but when you've got coworkers that behave in such a hateful manner....it totally makes everything 100 times worse.
I feel for you, and am happy to see you posted about this. I'd love to compare notes and offer/get advice on what has or hasn't worked for you

Let's share some stories

In my office, they play this stupid game where they mimick certain persons and specific times of the day. I was the lucky person today. They walk by at 10, 12, 2 and 3:30-- and do a walkby mimick (I work in walled cubicles). They mimick a persons voice/mannerisms. It's totally juvenile, and everytime they do it I feel like I'm 5 years old again and start feeling all insecure like a child feels when they're made fun of how they talk or something, etc.....
Logically I know it's childish, pointless, lame, and that they are just trying to get on my nerves....so why I get emotionally upset every time they do it,.... I dont know.

Any coping advice?
