United Steelworkers members, including those represented at a mine on the Iron Range, unanimously gave leaders authority to call a strike against ArcelorMittal should contract negotiators fail to produce results for about 15,000 workers across the nation.
ArcelorMittal is the largest iron mining and steel producer in the world. It has 18 facilities in the United States and employs about 300 union workers at the ArcelorMittal Minorca Mine in Virginia, Minn.
Company and United Steelworkers (USW) officials confirmed Tuesday that contract talks are ongoing in Pittsburgh after the Monday strike vote.
If a strike is called, union members would receive 48 hours notice, said Harold Anderson, president of the USW Local 6115 in Virginia.
Steelworkers labor contracts expired Sept. 1 for both ArcelorMittal and for U.S. Steel, which operates the Keetac mine and taconite plant in Keewatin and the Minntac mine and plant in Mountain Iron. The bulk of 16,000 union workers at U.S. Steel nationwide authorized a possible strike on Sept. 10.
Workers at both companies agreed to continue negotiating beyond the Sept. 1 contract expiration in the hopes of reaching an agreement. But tensions have remained high as the days drag on with no contract resolution.
ArcelorMittal officials said Tuesday its plants continue to operate in a "safe and orderly fashion."
"It is important to note that this is not a declaration of a strike, talks continue this week and we continue to work diligently to reach a mutually agreeable conclusion," the company said.
