Brigham and Women's Hospital has agreed on a contract with more than 3,000 nurses, avoiding a one-day strike.

The nurses' union announced the tentative agreement on Saturday. The union said the strike would have been the first strike by nurses in Boston in three decades.

A union representative calls the settlement a "huge victory," crediting the 3,300 nurses who "stood together."

Brigham and Women's Health Care President Betsy Nabel says hospital officials are "extremely pleased" the strike notice was rescinded.

The nurses must vote on the contract before it can be finalized.

Union representatives previously said the hospital doesn't value its nurses. Hospital representatives had said they could not reach agreement with the union on issues including staffing levels and compensation.

The two sides met with a federal mediator Friday.
