"...Many American women, until they get pregnant, have no idea that they are entitled to no paid leave under current law. Indeed, a study from Harvard University last year found that of 168 nations worldwide, the United States is one of only four whose government doesn't require employers to provide paid maternity leave. The others are Lesotho, Papua New Guinea and Swaziland.
