Arbitrator's Jurisdiction The arbitrator shall take such evidence as in his judgment is appropriate for resolution of the dispute; however, he shall confine himself to the issues for arbitration and shall have no authority to determine any other issue not so submitted which is not directly essential to reaching a determination on the dispute at hand. The arbitrator shall have no power to recommend any right or relief for any period of time prior to the effective date of the Agreement under which the grievance was initiated. In those issues wherein the grievant’s relief sought involves back pay or lost wages covering a period of an Employee’s payroll separation due to suspension or discharge, the amount of the award shall be less any unemployment compensation or interim earnings, received by the aggrieved Employee. Second jobs or sources of income which the Employee received while under employment will not be considered interim income and will not be deducted when awarding lost wages or back pay. The decision of the arbitrator shall be submitted in writing to the parties within thirty (30) calendar days of the hearing’s conclusion unless the deadline is mutually extended by the parties. The decision and award of the arbitrator shall be final and binding on the Union, its members, the aggrieved Employee(s) and the CITY. With respect to grievances involving misapplication or misinterpretation of this Agreement, the grievance and arbitration procedure contained in this Article shall be the sole and exclusive remedy available to employees, and the parties hereto as this procedure is intended to supersede all conflicting provisions of the Ohio Revised Code regarding any and all matters subject to the grievance procedures of this Contract or otherwise made subject to this Agreement. With respect to grievances involving disciplinary suspensions, demotions or dismissals the election of remedies, as set forth above, shall be mutually exclusive. Choice of binding arbitration shall thereafter preclude appeal to Civil Service or to Court. Appeal to Civil Service shall preclude access to binding arbitration. With respect to cases of suspension, demotion and discharge, the arbitrator shall decide:
