Nurses at Brigham and Women's Hospital in Boston and hospital management return to the bargaining table at 10:30 a.m. Saturday, trying to stop a strike set to begin Wednesday.

About 4,000 nurses, represented by the Massachusetts Nurses Association, plan to walk off the job at 7 a.m. on October 14. Unlike a strike this summer, this one has no end date. Talks on Thursday lasted 11 hours and ended without a deal, The Boston Globe reported.

The fight is mostly about pay. Nurses also want affordable health insurance and limits on the use of temporary travel nurses. The union says it offered "substantial compromises" Thursday, including a longer contract and a looser cap on temporary nurses.

The hospital says it is ready. Mass General Brigham, the parent system, plans to bring in 1,600 to 2,000 temporary nurses, many of whom filled in during a five-day stoppage in July. The Brigham will briefly pause new admissions at 5 a.m. Wednesday as teams switch. State health inspectors will be on site every day, State House News Service reported.

The two sides even disagree about Saturday's meeting. The union said the hospital will not send its "full negotiating team." A hospital spokesperson called that "not true."

Pay at the Brigham is already high by state standards. Nurses start at $86,700 a year, and nearly a third earn at least $220,000 after two decades, the hospital says. Nurses say an across-the-board raise is needed because of Boston's high cost of living.

Political pressure is building. Gov. Maura Healey and Boston Mayor Michelle Wu have urged a deal, and 66 state lawmakers signed a letter criticizing hospital leaders, Axios reported.

Nearby, nearly 2,000 nurses at Boston Medical Center ratified a new three-year contract this week, avoiding a separate strike.

What we know: The strike is set for Wednesday, and talks resume Saturday.
What we don't: Whether a deal can be reached in time.
