I’m faculty at a university. A significant number of my male colleagues have been accused of sexual harassment by students, and based on my own observations of my colleagues’ behavior, I find many of these accusations likely. My university is addressing this problem (sort of, and slowly). In the meantime, my responsibilities include advising students on which classes to take. I don’t want to spread gossip or get myself fired, but I also don’t want to send my advisees into situations that I know—but they don’t know—are not conducive to their learning, to put it mildly. What can I do here, as we wait for the wheels of history to turn slowly?
