The glass ceiling. It is still around, although not nearly as obviously as it once was. When I was growing up, women were housewives and mothers. If they HAD to work, they could be teachers, nurses, secretaries, or any of the other 'women's work'. Now, women can choose any career, but in too many institutions, the good ol' boy network is as strong as ever, and actively screening out women and others. There are too many law firms, financial institutions and other corporate structures where promotions are based, not on ability, but on being 'one of the boys'.
