For Artemis-
Found this in another forum and maybe you will find it as helpful as I do ---it is a brain training game that helps one ignore social negativity----it mentions call center people specifically in the study
"In another study we asked telemarketing operators to play the game each day for a week, before starting their daily shift. By the end of the week of dealing with people angrily hanging up on them, operators in the control condition felt -as you might imagine- stressed. Among operators who played the game before their shift, by comparison, they felt less stressed and more confident. Plus by the end of the week they had lower levels of the stress hormone cortisol in their system. "
Game can be found here as well as research info on its effectiveness:

I am dealing with a lot of negativity at work and I thought I'd try this. If you try it let me know if you find it effective!
