(1) Subject to subsection (2), an employee is entitled to be paid sick leave for actual illness or actual physical incapacitation without requirement of medical certification where—
(a) each such period of sick leave does not exceed 2 days; and
(b) the aggregate of such periods of sick leave does not exceed 12 days per annum.
(2) Where an employer reasonably believes that any purported sick leave, no matter how short, forms part of a course or pattern of absenteeism and is an abuse of sick leave provisions under this Act, he or she may require an employee to furnish him or her with a medical certificate.
