Sweatshops are a violation to the 24th Human Right Law. This law says: "Each work day should not be too long, since everyone has the right to rest and should be able to take regular paid holidays." Sweatshops obviously violate this because employees must work 16 hour days, and can't take any time off.
Sweatshops also violate the 4th Human Right Law. This law says: "Nobody has the right to treat you as his or her slave and you should not make anyone your slave." This law is in violation because the workers have no rights, and are often violated by the owners of the factories. Also, sweatshops have been linked with human trafficking.
