Union and hotel officials met yesterday for the first full day of negotiations in two weeks. But they said they did not come closer to a deal on a contract for 3,800 hotel workers at 14 hotels in the District who have been working without one since Sept. 15.

The two sides are expected to meet again Oct. 14.

"Today there was no progress," said Bruce S. Raynor, president of the union, Unite Here, after seven hours of negotiations in a church basement at 11th and K streets NW ended at 5 p.m. "The hotels didn't change their position one iota."

"We are extremely frustrated because there is another delay [in talks], and for the fourth time, the union has rejected our request to involve a mediator," said Lynn Lawson, a spokeswoman for the Hotel Association of Washington.

Discussion yesterday revolved mainly around health care costs, both sides said.

Among topics still pending is the length of a contract. The union wants two-year contracts for hotel workers in Washington, San Francisco and Los Angeles so that they will expire at the same time as pacts in New York and other major cities. The hotels are fighting that.

The Washington workers have voted to authorize a strike but have not walked out.

About 1,200 hotel workers in San Francisco are on strike, and about 2,800 other workers there were locked out of the hotels they worked in after the strike started Sept. 29.
