Ohio Rev. Code § 3319.031
Notwithstanding any provision of the Revised Code to the contrary, if the board of education of a city, local, or exempted village school district does not appoint a business manager under section 3319.03 of the Revised Code, the board may assign powers and duties specified in section 3319.04 of the Revised Code to one or more employees or officers of the board, including the treasurer, and may give the employees or officers any title recognizing the assignment of the powers and duties. The prohibition, in section 3319.04 of the Revised Code, against a business manager having possession of moneys does not prevent a board from assigning powers and duties specified in that section to the treasurer and does not prevent a treasurer who is assigned those powers and duties from exercising the powers and duties of treasurer. If the board assigns the duties of a business manager under section 3319.04 of the Revised Code to the treasurer, the treasurer shall not have the authority to make recommendations to appoint or discharge noneducational employees, except as provided under section 3313.31 of the Revised Code. Instead, the district superintendent shall be responsible for making recommendations, subject to confirmation by the board, for the appointment or discharge of noneducational employees.
