Thirty people have been arrested during a United Mine Workers of America protest against Patriot Coal in West Virginia.
UMWA President Cecil Roberts and AFL-CIO Vice President Arlene Holt-Baker are among those arrested.
The UMWA says 5,000 people attended Tuesday's protest in Fairmont.
They came from Alabama, Illinois, Kentucky, Missouri, Ohio, Pennsylvania, Virginia and West Virginia.
United Steelworkers President Leo Gerard told the crowd that every union is threatened if Patriot gets away with shedding legacy costs and breaking promises.
