Teachers must receive permission from the Board for all forms of leave which are not defined in statutes or in this Agreement. Deductions will be made at the per diem rate. The Board will engage and pay for the substitute. If under emergency or extenuating circumstances a teacher does absent himself/herself from his/her duties, he/she may request special consideration in writing and, on Board approval, obtain remission of the per diem deduction. The teacher shall submit the written request through the principal who will forward said written request along with his/her written recommendation to the Board.
