I would not do this. The boss will think you can't handle yourself. Just communicate on business things. Tell her that's what you are going to do to keep it professional. She can keep up her silent treatment for other things. The other people you work with are jealous, right?




. So I just stayed polite, tryed to work around her arrogance/immaturity. She ended up quitting

. Stay polite and call her bluff. Hopefully the drama won't last for months like mine did.
