Any party may seek bifurcation of a grievance to assert a claim of untimeliness. Bifurcation motions shall be presented in writing to the other party and the arbitrator in the moving party’s answer or at any time no later than seven (7) days prior to the scheduled hearing on the merits of the grievance. If an arbitrator has not yet been assigned to hear the grievance then the moving party shall file the motion with the Notice Arbitrator, who will decide the motion or assign it to a member of the Non-Injury Grievance Arbitration panel. A party’s decision to pursue a bifurcated hearing may not delay the processing of a hearing scheduled on the merits of the grievance. For any motions made at least thirty (30) days before a hearing on the merits of the grievance, the parties will use their best efforts to bifurcated hearing at least ten (10) days before the scheduled hearing on the merits of the grievance. In any case where a timely motion for bifurcation is made, but a bifurcated hearing is not held, the arbitrator shall decide the issue of timeliness during the hearing on the merits.
