From a post about why males AND females prefer to work for male bosses:

Women naturally prefer being under a man’s authority.

It’s unnatural to be under a woman’s authority if she isn’t related to you. Being under a woman’s authority feels sort of unstable. Traditional human tribal cultures were almost always led by male chiefs, and women naturally prefer that. When I worked in the public schools, I always preferred working under a male principal to working under a female one, even when the female principals were super nice. It just creates this feeling of security in a woman to take orders from a man; she’ll feel more desire to please a male boss and work harder to do so. If she does well and he praises her, she will feel more satisfaction than if her boss were a woman. As adult women, we were designed to submit to men, not to other women, and it feels unnatural to us to be bossed around by a woman.
