The Employer shall post, in the school, a notice of each new position and each vacancy to be filled by teachers/administrators who would come under this agreement at least 10 teaching days before the position or vacancy is to be filled. Concurrently, a copy of such notice shall be sent to the Association. For greater clarity, a vacancy shall mean a position where the incumbent has retired, resigned or been assigned to other duties or terminated and where the Employer has determined that the position is to be filled.
