theodp writes: TechCrunch reports that Facebook CEO Mark Zuckerberg will take two months off from Facebook for paternity leave. Why? "Studies show that when working parents take time to be with their newborns, outcomes are better for the children and families," Zuckerberg explained in a FB post on Friday. "At Facebook we offer our U.S. employees up to 4 months of paid maternity or paternity leave which they can take throughout the year." No word on why the child will only get 50% of that time — maybe that's what the gains chart suggested as a good tradeoff — or if expectant parents who apply to send their children to Zuckerberg's new Primary School, which aims to "help children from underserved communities reach their full potential," will be expected to make a similar commitment.
