PITTSBURGH — The United Steelworkers have announced a tentative agreement on a new three-year contract with ArcelorMittal USA covering nearly 14,000 workers.

The union told members Saturday they would be getting details soon as well as dates and locations of informational meetings before a ratification vote. Officials said the current contract, which expired Sept. 1, would be extended until then.

The statement said retiree health care was one of the most important issues, and union officials believe they have negotiated a framework that will protect both current and future retirees.

ArcelorMittal representatives did not immediately return messages seeking comment.
