General Motors increased vehicle production in October even as sales fell, an indication it might be preparing for a strike at auto supplier Delphi.
GM spokesman Stefan Weinmann says there have been no disruptions in supplies from Delphi and GM has been assured shipments will continue as Delphi restructures in bankruptcy court.
Weinmann wouldn't say whether increased production is part of the company's plan to deal with a possible strike.
GM's sales were down 23 percent in October from a year ago, but the world's largest automaker increased North American production by eight percent.
A schedule released yesterday shows GM plans to run at least ten of its plants on overtime next week. GM also said it's adding extra shifts to plants in Delaware and Louisiana.
