PACT IS REACHED AT 1 OF 13 PLANTS
Negotiators for General Motors and the United Automobile Workers continued bargaining on national issues early today as about 58,000 workers prepared to prevent 11 plants from resuming production today. However, because bargainers were unable to reach an agreement early enough to notify workers, it appeared all but certain that a strike would continue even if an accord was reached before work was scheduled to begin. A settlement on local issues was reached Sunday night at a plant in California, one of 13 struck Friday, the union announced. The Associated Press quoted K. C. Beck, personnel director at the California plant, as saying the settlement had ''nothing to do with the national agreement.''
