I'm glad to see someone finally discussing second-generation gender bias in the context of all the recent equal pay discussions. Why in so many different professions do women start out in equal numbers to men at entry level, but when you get to the top you see they have almost all dropped off the path to advancement? According to this article, it's because the path to advancement "is often interrupted for a simple reason: when women display leadership behaviors we consider normative in men, we see them as unfeminine. When women act more feminine, we don’t see them as leaders." This is the classic double bind that is the heart of second generation sexism. Either way, we lose. It is sexism reinforcing itself. Circular reasoning.
Studies also show women do not receive the same desirable or lucrative projects or assignments that would allow for advancement within a company. And women don't have the same opportunities for mentorship by leaders at the top. These vicious cycles are simply the reality of sexism reinforcing itself, again and again.
