Notwithstanding AS 39.20.200, an officer or employee is entitled to personal leave only after having been employed currently for a continuous period of 30 days under one or more appointments without break in service. When an officer or employee completes a period of continuous employment of 30 days, an amount of personal leave is credited to the officer or employee equal to the amount which, but for this section, would have accrued under AS 39.20.200 during the period.
