A three-year contract agreement has been reached between the Niagara Falls Memorial Medical Center and the 650-person 1199 SEIU United Healthcare Workers East union at the hospital. Union members will have a ratification vote later this month.

Details of the agreement were not released.

Negotiations began in September and were joined by a federal mediator in December, the union said in a release.

The previous contract expired in December and was extended during the talks.
