I am female. I have had male and female bosses. Some of each sex were good, some of each sex were only adequate. The worst I had was a male. I do not think his stupidity was a male trait, but was caused by his being a jerk. If there is discrimination against females it may be that the female jerk does not get promoted as frequently as the male one does. Just my opinion.
I was in upper management for many years. I never had any problems with my employees based on gender that I can think of. Some women I think had problems taking orders from another woman but they usually got comfortable with it. All my bosses were men, and some of the other women managers would always give them grief, and the men would just let them get away with it because they were afraid of a discrimination suit. Women aren’t helping themselves any a thing like that, in my opinion.
