VANDALIA, OH - APRIL 3: The Delphi Automotive Systems Safety & Interior Systems Sign is seen April 3, 2006 in Vandalia, Ohio. Delphi asked a federal bankruptcy court to void its labor contracts as part of a restructuring plan that includes selling or closing 21 of its 29 U.S. plants. Six of the ten plants set for closure or sale are in Ohio, four within the Dayton area, and employ 7,500 plant workers. The Dayton area plants have an annual payroll of $260 million and in 2005 paid about $12 million in income and property taxes to local governments. (Photo by J.D. Pooley/Getty Images)
