Volkswagen's union said it was gearing up for strikes across German factories from Dec. 1 after talks over wages and unprecedented factory closures at Europe's largest carmaker failed to achieve a breakthrough on Thursday.

Volkswagen wants to slash wages 10% and eliminate bonuses as they’re struggling with an assortment of headwinds. However, the automaker has previously said the union wants a 7% pay increase as well as the reinstatement of terminated agreements.

Volkswagen AG workers across Germany plan to stage mass walkouts starting early next month after labor leaders and management failed to reach an agreement over how to slash costs at the carmaker’s namesake brand.
