I am always the mediator in the office wars between the various females that work here and I can tell you that it is not pretty dealing with the women at my office who are in positions of power. It is constant drama. Seriously. Every day is like a bad movie off of the Lifetime Channel. Who-said-what-about-who, who-is-out-to-get-who, who-does-she-think-she-is, I'm-going-to-get-her-back-for-that, etc., etc., ad nauseum.
I'm sorry the women you work with are llike that. I've been in the workforce for 20+ years, working with men and women, and behavior like that has been the exception. Please don't attribute the negative traits of your co-workers to all women.
