The U.S. Supreme Court will hear oral arguments on Jan. 19 in a case involving a dispute between construction materials company Graniterock Co. and the International Brotherhood of Teamsters.
The case centers on whether a company may sue a third party—in this case, an international union—that was not a signatory to a collective-bargaining agreement but waged a strike against the company. Graniterock, a Watsonville, Calif., supplier of rock, concrete and other materials, claims the Teamsters’ international union unlawfully interfered with the collective-bargaining agreement Graniterock had established with Teamsters Local 287.
