I was recently passed over for a promotion to management, and I think it's because I'm a woman. My manager sometimes makes questionable comments about mothers working outside the home, women being more emotional than men, and so on. He has never promoted a woman in the few years that he's been responsible for making these decisions. At the same time, though, there haven't been many total promotions, and none of the men he selected are obviously unqualified. I'm not sure what to do; would I have a good sex discrimination case in these circumstances?
