(B) The director of administrative services may establish a program under which an employee paid directly by warrant of the director of budget and management may donate that employee's accrued but unused paid leave to another employee paid directly by warrant of the director of budget and management who has no accrued but unused paid leave and who has a critical need for it because of circumstances such as a serious illness or the serious illness of a member of the employee's immediate family. If the director of administrative services establishes a leave donation program under this division, the director shall adopt rules in accordance with Chapter 119. of the Revised Code to provide for the administration of the program. These rules shall include, but not be limited to, provisions that identify the circumstances under which leave may be donated and that specify the amount, types, and value of leave that may be donated.
