AK Steel officials and union leaders say they won’t put up with racial intolerance at its plant in Butler, Pennsylvania. The comments come after the filing of a federal lawsuit that says black employees have been intimidated by racist language, swastikas, nooses and a Ku Klux Klan video at the plant. The U.S. Equal Employment Opportunity Commission says in the lawsuit that the problems have been so bad that managers had to know about them before black employees complained. A spokesman for the Middletown, Ohio-based steel-maker says the company has no tolerance for harassment and doesn’t believe the lawsuit has merit.
