the US ranks at the bottom of all industrialized nations when it comes to parental leave, guaranteeing only twelve weeks off after the birth of a child. If you work for the government or a private company with more than fifty employees, that is. Only a little more than half of all American moms meet those criteria, and nearly a quarter of American moms go back to work just two weeks after giving birth. Forget about pay, unless you work for an unusually generous employer.
