any participating International Union. Failure to comply with this section is a violation of this Agreement.

4. For short-term (less than 5 working days) or weekend projects, the Employer may contact the appropriate crafts via telephone, FAX and/or other electronic means, regarding work assignments. For projects of longer duration, the Employer shall convene a pre-job conference, upon sufficient notice so that all appropriate crafts have an opportunity to participate.

5. During the existence of the National Maintenance Agreement, there shall be no strikes, lock outs, work stoppages, or picketing arising out of any jurisdictional dispute. Work will continue as originally assigned, pending resolution of the dispute.

Since presently established jurisdictional dispute settlement procedures are not applicable to work covered by the Agreement, all signatory Unions and all signatory Employers stipulate that they will abide by the following procedures for the resolution of jurisdictional disputes. A party challenging an assignment shall notify all affected parties, i.e. Unions and Employer as well as the NMAPC office, by telegram or FAX, within two (2) days of the time that a dispute occurs at the local level. All disputes involving craft work assignments shall be referred to the International Unions with which the local unions are affiliated and they and the Employer shall have the opportunity to resolve the dispute.

7. Should the International Unions and the Employer fail to resolve the dispute within five (5) work days from the date they were notified of the dispute, then the matter shall be referred by telegram or FAX by any International Union or Employer directly involved in the dispute for arbitration to the Permanent Umpire, designated by the NMAPC, to resolve jurisdictional disputes under this procedure.

8. The Umpire will set and hold a hearing within seven (7) days of the referral to him. The Umpire shall notify the Employer and the appropriate International Unions by telegram or FAX of the place and time chosen for the hearing. A failure of any party or parties to attend said hearing without good cause, as determined by the Umpire, shall not delay the hearing of evidence or issuance of a decision by the Umpire. The time period set forth herein can be extended by mutual agreement of the parties in writing.

9. The Umpire shall issue his decision within three (3) days after the case has been closed. The decision of the Umpire shall be final and binding on all parties to the dispute. This action of the Umpire shall be predicated upon the particular facts
