A Delco strike may halt GM’s assembly lines.

General Motors laid off 33,350 workers until further notice in Michigan, Kentucky, Missouri, Ohio, Kansas, Delaware and New Jersey due to parts shortages caused by the 7,700-worker strike at a Delco Electronics plant in Kokomo, Ind., GM spokesman John Mueller said. “If the strike goes--well, not even too much longer--we will be completely shut down,” GM Chairman Roger Smith said. The manager of GM’s Van Nuys plant, Ernest D. Schaefer, said his facility has enough parts to keep operating at least through Tuesday morning.
