Tentative Phone Pact Reached

Negotiators for 38,000 unionized telephone workers agreed tentatively on a contract with NYNEX Corp. today and called off an eight-day strike against the New York and New England telephone companies, officials said.

The Communication Workers of America instructed its members to return to work as of midnight, union and management bargainers said in a joint statement. NYNEX was the last of the seven regional Bell phone companies to reach a tentative settlement with its major unions. A date for a ratification vote has not been set.
