All Depends on which regional supplement you fall under. Guessing that you are covered under the western supplement. Since, "When a driver’s assigned delivery area is permanently changed by fifty percent (50%) or more of its delivery stops, said driver shall have the right to follow the major portion of the original delivery area. When more than one (1) driver’s delivery area is affected, those affected drivers shall be afforded the opportunity amongst themselves to bid the areas affected in accordance with their seniority."
