Teacher on Authorized Unpaid Leave. If a teacher is on an authorized unpaid leave for an entire school year and receives no portion of his/her annual salary, he/she does not have the right to participate. While his year is not counted toward the continuous service of this employee, this authorized unpaid leave shall not interrupt the status of “continuous service” for determining eligibility of an employee. A teacher on a short-term unpaid leave of absence shall have their contribution pro-rated.
