If an employee uses sick leave for more than three consecutive scheduled workdays, an employer may require the employee to provide reasonable documentation to verify the employee's need for the sick leave if the employer has included the verification requirement in the employer's sick leave policy and has provided the sick leave policy to the employee. An employer may not require the verification to explain the nature of the employee's illness or details related to domestic violence, sexual assault, harassment, or stalking that necessitated the employee's use of sick leave. Days that an employee is not scheduled to work are not included in the calculation of three consecutive scheduled workdays under this section. If an employer has requested verification of an employee's use of sick leave under AS 23. l 0.067(3) or this section, the employer is not required to pay sick leave until the employee has provided the requested verification.
