Back in August, GM workers in Mexico decertified their long-standing contract with the historically corrupt Confederation of Mexican Workers union. This week, over 6,000 of those workers voted to adopt (with 78% approval) an independent union under the watchful gaze of U.S. officials. The case could bring big developments regarding the Trump-negotiated 2020 United States-Mexico-Canada Agreement (essentially a NAFTA-replacement trade deal, which was forged with the intent of ending Mexican labor-system corruption). As for how this “test” case will ultimately reflect upon the new trade deal, only time will tell.
