Didn't you say that the other girls had asked you how you made so many calls and you gave them your system? If they start harrassing you or otherwise being unpleasant, tell them that you gave them your secret. Now it's up to them to make it work.

If it comes to push to shove, tell your supervisor about your system and that the other girls have it to use, too. It would be nice if everybody got along. You're doing your part. Seems they aren't and like Gimmeice said, it's better to be disliked than unemployed. You gotta cover your own back.

My mom used to work in a blue jean factory and she worked harded than the rest of the women; always surpassed her quota so that she could go home early and be home when I got home from school. She was well disliked, too, for making the rest of the women look bad.

It happened to me, too, when I used to work in what they called the typing pool. When I took a leave of abscent for the summer to be home with my three kids, one of my friends who worked in another department had a luncheon for me. All the engineers showed up but none of the women in the typing pool did. I didn't bother coming back in September. LOL My husband wanted me to stay home with the kids, anyway.
