Mexico extends deadline to repeat disputed GM contract vote

Authorities warned the plant’s collective contract would be terminated if the extended deadline is missed.

Mexican authorities on Monday extended the deadline for the union at a General Motors Co plant in Silao, Mexico, to redo a disputed contract vote that has drawn US scrutiny, warning the plant’s collective contract would be terminated if the date is missed. The union at the plant in the central city of Silao must hold the vote before August 20, the labour ministry said in a statement. The plant employs about 6,000 people. The original union-led vote in April, in which workers voted on whether to keep their current contract, was scrapped halfway through after Mexican officials detected “serious irregularities”, including destroyed ballots.
