Supplier Strike Interrupts Output at GM

General Motors Corp. halted production for several hours at two assembly plants, in Oklahoma and Texas, because of a strike at a parts supplier, the company said. A walkout at Mackie Automotive Systems facilities stopped work at GM’s Oklahoma City plant, which makes Chevrolet Malibu and Oldsmobile Cutlass cars, and at a plant in Arlington, Texas, where Detroit-based GM builds full-size extended-cab pickup trucks and full-size Tahoe, Denali and Yukon sport-utility vehicles. The Arlington factory’s first shift was sent home about four hours early after running out of parts. Work resumed later in the day and is scheduled to continue tomorrow, a GM spokesman said. “We will continue to work as long as we get parts, and we are still getting shipments from Mackie,” said Tom Beaman, a GM spokesman. Mackie workers are represented by the United Auto Workers union. Neither Mackie nor union officials could be reached.
