U.S. Steel has a tentative agreement with leaders of the United Steelworkers. Local unions at U.S. Steel’s MinnTac and Keewatin Taconite plants will have to ratify the three-year deal. Cliffs and ArcelorMittal have yet to settle with the Steelworkers, but the U.S. Steel deal suggests the others will follow with similar deals this week. Details of the contract will emerge once the locals get a look at the deal.
