(a) An officer or employee of the state who is otherwise qualified to take leave of absence may take family leave because of a serious health condition for a total of 18 workweeks during any 24-month period. An otherwise qualified officer or employee may take family leave because of pregnancy and childbirth or adoption for a total of 18 workweeks within a 12-month period; the right to take leave for this reason expires on the date one year after the birth or placement of the child. An officer or employee taking leave under this section shall use accrued paid leave until the officer or employee has only five days of paid leave remaining. The officer or employee may choose whether to retain a balance of five days of paid leave and take the remaining leave as unpaid leave or whether to exhaust the paid leave balance.

If the employee is entitled to a longer period of time under AS 39.20.500, then the longer period applies. An eligible employee is entitled to take family leave
