The grievance procedure is not arbitration. After deadlocks at the local level, the regional level, the conference level and finally the international level, the union has a strike option. Some contracts may have an arbitration option but only after the grievance procedure is exhausted. Each grievance procedure level has a cost. Arbitration is a legally binding, non appealable, decision by a single independent arbiter of fact. An alleged contract violation will never be heard by a court if there is a contractual grievance procedure in place. Any decision, at any level, ends the process with no option to appeal.
