The Division of Personnel after consultation with other state agencies shall establish a program under which annual leave accrued or accumulated by an employee of an agency may, if voluntarily agreed to by the employee, be transferred to the annual leave account of another designated employee if the other employee requires additional leave because of a medical emergency. The annual leave program shall be established by legislative rule pursuant to the provisions of chapter twenty-nine-a of this code. The Division of Personnel shall file such legislative rule no later than July 15, 1995. The division shall prepare an annual status report to be presented to the Joint Committee on Government and Finance no later than January 5, each year. A "medical emergency" means a medical condition of an employee or a family member of the employee that is likely to require the prolonged absence of the employee from duty and which will result in a substantial loss of income to the employee because of the unavailability of paid leave. As used in this section, "employee" includes employees in the classified and classified-exempt service and employees exempt from coverage who are under this article entitled to annual leave as a benefit of employment: Provided, That none of the leave so transferred may be used to qualify for or add to service for any retirement system administered by the State of West Virginia.
