GM faces a one-day strike at its European plants next week in protest at production cuts, the Financial Times newspaper reports.
Employees at the Antwerp plant are already on a week-long strike over the decision.
The company’s European labour representatives called for a day of action next Thursday as part of efforts to press for a deal on GM’s factory in Antwerp.
GM last week announced plans to shed 1,400 jobs – a third of the workforce – at its Belgian site as it reduces manufacturing of the current Astra model prior to its replacement in 2010 with a new Astra that will be made elsewhere in Europe.
The newspaper said that GM would not say which model it might build in Antwerp. However, the report said that industry sources believe that the likeliest candidate would be a model produced by Chevrolet, its value brand, for which GM is developing a new low-cost car.
