The Supreme Court stepped into a dispute Tuesday over whether white managers can be sued for calling black employees ``boys.'' The court unanimously overturned an appeals court decision that said the term ``boy'' alone was not evidence of workplace discrimination and ordered the court to reconsider the matter. The decision, one of the first actions with new Justice Samuel Alito, is a loss for Tyson Foods Inc. which was sued by two longtime black employees who claimed they were passed over for promotions by a white manager who called them ``boys.''
