The broken rung: a phenomenon even more pervasive than the glass ceiling in holding women back from career success. Women around the world do extremely well when it comes to their education. They graduate at higher rates than men do and have higher average GPAs. But then a strange thing happens: Upon entering the workforce, they immediately lose their advantage. When the first promotions come around, the slide continues—for every 100 men who are promoted to manager, only 81 women get promoted. This is what McKinsey senior partners Kweilin Ellingrud, Lareina Yee, and María del Mar Martínez call “the broken rung,” and its effects compound throughout women’s careers, causing women to fall behind at the start and keeping them from catching up.
