The U.S. Equal Employment Opportunity Commission will sign a national memorandum of understanding with the Mexican government on Friday, pledging to help protect the rights of Mexican citizens working in the United States.

The pact, which will be signed by EEOC Chairwoman Jacqueline Berrien and Mexican Ambassador Eduardo Medina Mora, follows a series of agreements with by local EEOC offices and Mexican consulates in Dallas, Miami, New York, Detroit and elsewhere.

The memorandum is “designed to further strengthen their collaborative efforts to provide immigrant, migrant and otherwise vulnerable Mexican workers and their employers with guidance and information and access to education relative to their rights and responsibilities under the laws enforced by the EEOC,” the agency announced.

The EEOC for years has declared the “settled principle” that federal employment discrimination statutes cover undocumented workers. Although it is illegal for employers to hire people who are not authorized to work in the United States, it also is illegal to violate their civil rights.

According to the EEOC, “If employers were not held responsible for discriminating against unauthorized workers, it would create an incentive for unscrupulous employers to employ and exploit these workers. This would directly undermine the enforcement of the immigration laws by encouraging the employment of unauthorized workers.”

In its latest strategic enforcement plan, the EEOC included protecting immigrant workers as a top priority.
