Essentially there are three main reasons women are nasty to other women:
• Because they project their unwanted parts onto the other women (especially their fear, envy, jealousy, suspicion, resentment, rage, anxiety or lack of self esteem & confidence)
• Because they can get away with it (as a sport, fun, panacea to boredom, delight in spite, and their lack of curiosity/tolerance of difference suggests they probably don’t like people anyway)
• Because they don’t have the interpersonal and intrapersonal communication skills to recognize or alter their behavior.
With nasty women, it is usually their unconscious FEAR or need for control being triggered by the new staff member, or the different woman at work who threatens them.
