I believe most successful corporate types are called names behind their backs regardless of genders. A woman is more likely to be called a b--ch while a man is more likely to be called an a-hole.
Some employees, underlings, and competitors either have a jealous streak or they resent the fact that such an individual has power over their career and income opportunities at that company.
Anyone who takes on a leadership role needs to have a tough skin.
Oftentimes the most popular person in a company has a low level position. Everyone likes her/his personality and smiling face.
