People can engage in reverse discrimination in the U.S., and specifically in the employment sector, by appealing to the framework of laws which have been implemented by legislators to prevent discrimination from being practiced in the country, either when people are being considered for potential employment or after they have been hired.
The ability to reverse discrimination is enumerated as a Government function in U.S. Constitutional law, though specifically toward discrimination that is specifically carried out in the employment context of the Government.
In order to prevent discrimination from also occurring in the context of private industry and commerce, laws for reverse discrimination have been gradually passed and put into effect, both at the state or Federal levels. In the latter category, for laws of reverse discrimination, discrimination can be prevented in a number of forms, such as discrimination for reasons of race, sex, nationality, mental or physical disability, or pregnancy.
