Damn, US workers are getting screwed! Not just in maternity leave, but in annual leave as well.
US law does not require employers to grant any vacation or holidays, and about 25% of all employees receive no paid vacation time or paid holidays. Many US State and local governments require a minimum number of days off; for employees that do receive vacation in the U.S., ten working days with eight national holidays is fairly standard.
That's disgraceful.
