The #MentorHer campaign could perhaps be viewed as a form of mentorship itself, for executives who feel wary now about their working relationships with women. Sandberg’s advice? “Men who want to be on the right side of this issue shouldn’t avoid women. They should mentor them.”

As for the men who still don’t feel comfortable dining alone with a female colleague, Sandberg says, “Fine. But make access equal: no dinners alone with anyone. Breakfast or lunches for all. Or group dinners only, nothing one-on-one. Whatever you choose, treat women and men equally.”
