I have always thought the whole glass elevator phenomena is kinda weirdly anti-sexist in a way and I'm not sure how you resolve it. I don't think boards of struggling companies are looking to screw over a female exec when they hire her, I think what they are doing is scrambling to try and change up the dynamic of the company's leadership in a positive way, but more often than not a company that is struggling is already on an inevitable path to failure. I think the bigger question/issue is why aren't these big companies ever looking to make these positive/diverse hirings even during the good times?
