The U.S. is one of only four countries in the world that does not guarantee the right to paid maternity leave. To better understand the disparities that exist in the tech industry when it comes to supporting employees with families, I examined parental-leave policies at 15 different tech companies across sizes, verticals, and locations. Leading tech companies like Facebook, Apple, Google, and Yahoo offer some of the most generous parental leave policies in the U.S. Among this group, Facebook is the only company to offer equal time off for all parents, whether they are the birth mother, father, or adopted parents. All new parents at Facebook receive four months of paid leave, as well as $4,000 in "baby cash." In the past year, Facebook introduced designated breast-feeding rooms at its Menlo Park location. In addition, it offers financial and logistical assistance with adoption and fertility services, including the controversial coverage of egg-freezing costs, which Apple also offers.
