A Mexican subsidiary of Panasonic’s automotive division is violating its workers’ labor rights by denying them a choice in union representation and by forcing an unapproved collective bargaining agreement upon them, according to a new petition to trigger the U.S.-Mexico-Canada Agreement’s rapid-response mechanism.

The petition was filed by Rethink Trade, a program of the U.S.-based advocacy group American Economic Liberties Project, and Sindicato Nacional Independiente de Trabajadores de Industrias y Servicios, a Mexican labor union, the two organizations announced on Monday. They allege that Panasonic Mexico is not only violating labor rules but also retaliating against workers that have aligned themselves with SNITIS, according to a copy of the petition obtained by Inside U.S. Trade.

The U.S. has previously invoked the UMSCA rapid-response mechanism in two separate instances, successfully resolving concerns – both at Mexican facilities – with pledges for fair labor elections and other redress efforts.

“Bold action from the U.S. government using the Rapid Response Mechanism led to two independent unions winning elections at GM Silao and Tridonex. We are confident that the Biden administration will act accordingly in this case and work with the Mexican government to address this troubling state of affairs at Panasonic,” Daniel Rangel, of Rethink Trade, said in a statement.
