Although much can be said about the efficiency of arbitration as a method of private dispute resolution, arbitration is not always private. Sometimes, awards have the capacity to touch the lives of countless individuals whose identities are unknowable and whose interests are not represented at the time of the arbitral trial. This is nowhere more true than in labor arbitrations regarding the discharge of a union member.
