All employees are subject to being summoned for off-duty work in case of emergency and shall respond accordingly. Lack of action thereof by any employee shall be a violation of the personnel policy. A personal emergency that would require his attendance would be a justifiable reason for not responding but the employee shall notify his immediate supervisor that he cannot respond to the emergency. It shall be the responsibility of the supervisor to respond to the emergency or to designate another person to respond to the emergency.
