In event of the extended illness of an employee and after having exhausted all accumulated sick days, bonus days and vacation days, then a request may be made to the Director of Human Resources for extended sick pay benefits. The employee's prior work record with regard to his/her usage of sick days and his/her seniority will be taken into account in determining the eligibility of the employee for such extension. In the event a sick and accident insurance benefit mutually agreeable is secured, then this benefit shall be discontinued.
