Ind. Code § 4-37-5-3

Sec. 3. The board may develop a separate personnel system for employees of the corporation. The system may establish the rights, privileges, powers, and duties of the corporation employees, including pay scale and benefit package. If the board does not develop and adopt a personnel system, the employees of the corporation are subject to the state personnel system under IC 4-15-2.2. If the board does adopt a separate personnel system, the rules should mirror the state personnel rules as closely as possible.
