N.C. Gen. Stat. § 95-36.7
Upon the selection or appointment of an arbitrator or arbitration panel in any labor dispute, a statement of the issues or questions in dispute shall be submitted to said arbitrator or panel in writing, signed by one or more of the parties or their authorized agents. The arbitrator or panel shall appoint a time and place for the hearing, and notify the parties thereof, and may postpone or adjourn the hearing from time to time as may be necessary, subject to any time limits which are agreed upon by the parties. If any party neglects to appear before the arbitrator or panel after reasonable notice, the arbitrator or panel may nevertheless proceed to hear and determine the controversy. Unless the parties have otherwise agreed, the findings and decision of a majority of an arbitration panel shall constitute the award of the panel and, if a majority vote of the panel cannot be obtained, then the findings and decision of the impartial chairman of the panel shall constitute such award. To be enforceable, the award shall be handed down within 60 days after the written statement of the issues or questions in dispute has been received by the arbitrator or panel, or within such further time as may be agreed to by the parties.
