For employees of higher education institutions or related higher education boards, anniversary date is the most recent date of hire into state service. The anniversary date is used to determine when vacation leave over two hundred forty (240) hours is lost. Higher education employers may make the anniversary date the first calendar day of the month in which the date of hire occurred. A higher education employee receives a new anniversary date when that employee is rehired following a break in state service, but not when the employee promotes, demotes, or transfers to another higher education employer.
