Teachers who have been granted a Leave of Absence and are eligible to continue to participate, during their absence, in group payroll deduction benefit plans, may request in writing that the Division make premium payments under such plans. The teacher wishing to commence a Leave of Absence shall prepay to the Division a sum of money equal to the total premium for the period of the Leave of Absence. The Division shall thereupon make payment(s) under the plan(s) on behalf of the teacher during such Leave of Absence. In the event of a rate change in any of the plans during the duration of the Leave, the Division shall inform the teacher of the additional sums of money necessitated by the change. Failure on the part of the teacher to forward such sums necessitated by the change in rate shall be deemed to be notice that said teacher no longer wishes continuation of premium payments, and the Division shall give notice to the teacher of such discontinuation and forward to that teacher any residual monies to which the teacher may be entitled.
