I have spent many hours talking with colleagues in international development about how to tear down the barriers that block women’s progress around the world. Now, we’re confronting the fact that every sector, including our own, has a serious problem with sexual harassment and violence. The norms that allow these abuses are the same ones that disempower the poorest women, and only when they are dismantled across the globe will all women and girls be able to lead the lives they want.
