A strike by cashiers and clerks at Acme supermarkets in southern New Jersey was avoided Saturday, although the supermarket chain and the union representing the workers had still not agreed on a new contract by Friday night, a union spokesman said.

Bob Wolper, speaking on behalf of United Food and Commercial Workers Local 1360, said Saturday that talks may continue as soon as Monday.

About 2,400 members of Local 1360 — working at Acme stores in Cumberland, Burlington, Salem, Camden, Gloucester and Mercer counties in New Jersey, and in lower Bucks County, Pa. — are threatening to strike before Thanksgiving if a contract cannot be worked out with their employer. The union, based in Berlin Township, Camden County, says health care benefits and salaries are major issues. Workers have gone without a new five-year contract since April.

Acme’s parent company, Minneapolis-based Supervalu Inc., says it wants a “mutually beneficial contract” and to avoid a strike.
