A recent SJC decision illustrates the unfortunate position in which a party may find itself when it fails to file an appeal but finds itself before an appellate court nonetheless as a result of an appeal filed by the opposing party. In Town of Athol v. Professional Firefighters of Athol, Local 1751, 470 Mass. 1001 (2014), the Supreme Judicial Court considered arguments that arose when town of Athol unilaterally raised the co-payments paid by members of a firefighters' union for medical services. After the union filed a grievance, alleging that the town's action had violated its collective bargaining agreement, the matter proceeded to arbitration. An arbitrator determined that changes to health insurance benefits were mandatory subjects of collective bargaining and the town had violated the collective bargaining agreement by making the changes unilaterally. The arbitrator required the town to return the co-payments to their original amounts and to "make union members whole for economic losses" incurred as a result of its improper action. The town appealed the arbitrator's award, filing a complaint in the Superior Court.
