Exchange of Base/Location. Two or more employees who have completed their probationary period may file a request with the Human Resources Department to exchange bases or locations. Such requests will be reviewed at each Union-Management Headquarters Meeting and will be actioned following approval by the Company and the Union, subject to final written acceptance by the employees involved. Such exchange will not create a vacancy and approval of the exchange will not be unreasonably withheld. All costs to the employees associated with the exchange will be the responsibility of the employees involved and the provisions of Article 19.09 will not apply.
