A judge rejected a bid by bus drivers for the Pulaski County school district who sought to force the district to comply with a disputed contract. Circuit Judge Barry Sims ruled yesterday that the Pulaski Association of Support Staff had not reached a final contract with the district when bus drivers went on strike in January. The union had sought an injunction to force the district to comply with a contract the school board tentatively ratified in August. Several issues were pending further negotiation. But Sims refused to grant the injunction, saying that the agreement was never final. The drivers stopped work January 26th over wage issues. The school board granted the pay concessions but, on a four-to-three vote, ended recognition of the union.
