From the Document: "The U.S.-Mexico-Canada Agreement (USMCA) entered into force on July 1, 2020, replacing the North American Free Trade Agreement (NAFTA). USMCA establishes new and updated provisions on the protection of worker rights and enforcement of labor commitments. Congress approved implementing legislation for USMCA (H.R. 5430) on December 19, 2019. President Trump signed the legislation into law on January 29, 2020 (P.L. 116-113). The protection of worker rights and the enforceability of labor provisions were a major congressional concern throughout the USMCA negotiations and remained an issue after the three countries concluded the agreement in September 2018."
