In 2012 Sheryl Sandberg, then the chief operating officer of Facebook, said in a video interview: “I walk out of this office every day at 5:30 so I’m home for dinner with my kids at 6:00.” She said that only in the last year or two had she been brave enough to talk about it publicly.
According to reports of the interview, she sent emails early in the morning and late at night to show she was still working.
