For Women To 'Lean In', Who Needs To 'Lean Out'?

Sheryl Sandberg's 2013 book, "Lean In," considered what roles women take on in the workplace. The phrase refers to Sandberg's mantra that women should "lean in" professionally, and go head-first after their career goals. But now, three years on, after focusing on how to lean in, have we overlooked the other side of the coin? In this case, the other person or partner, who needs to lean out?
