But this level of adoption isn't always the case when it comes to generous leave policies.
Stewart Friedman, a professor at the University of Pennsylvania's Wharton School, previously told Business Insider that when he studied unlimited-vacation policies, the main issue he saw was employees' fear of using vacation days and looking less committed than their colleagues.
Andrew "Boz" Bosworth, vice president of the 600-person ads and pages team, previously told Business Insider that people at Facebook are passionate about what they do, so it's natural for parents to feel like they'll miss out on their work.
He strongly encourages all his dads and moms to take their full leave - it's all about making the right guarantee.
"It's really irresponsible for any member of the company, parent or otherwise, to have information or an ability that [nobody else has], because that means it's a liability to the company," he said. "If you're a single point of failure, especially in an engineering organization like Facebook, that's strictly a bad thing."
Zuck's announcement demonstrates that this idea is just as much at play for the CEO as anyone else in the company.
