28.5 End-of-Year Notice Requirement. Teachers resigning or retiring prior to the start of the next school year must give notice by March 30th (90 days prior to the end of the preceding school year). Teachers providing less than the 90-workday notice, but more than 30-days notice, shall receive a prorated severance payment; i.e., a teacher giving 89-days notice shall be eligible for 89/90ths of the severance benefit. Teachers giving less than 30-days notice shall not be entitled to any severance benefit, assuming there are no extenuating circumstances. A written notice should be sent to the Assistant Superintendent, Human Resources.
