MEXICO CITY (AP) — Mexico faced its biggest challenge yet Friday to labor-freedom reforms under the U.S.-Mexico-Canada trade agreement after an old-guard union was caught apparently destroying negative ballots at a General Motors plant in northern Mexico.
Labor Secretary Luisa Maria Alcalde said the vote tampering at the pickup truck and transmission factories in the northern city of Silao were a sign that some union leaders “haven’t gotten the message” that they can no longer operate behind the backs of workers.
