Ohio Rev. Code § 2947.15
Persons committed to jail by a judge or magistrate for nonpayment of fine, or convicts sentenced to hard labor in the county jail, shall perform labor under the direction of the board of county commissioners within or outside the jail, within the county, and the board shall adopt orders and rules in relation to the performance of labor and the sheriff or other officer having the custody of the persons or convicts shall be governed by the orders and rules. The sheriff of the county shall collect the proceeds of the labor of the persons or convicts, pay it into the county treasury, take the county treasurer's duplicate receipts for the amount paid, and forthwith deposit one of them with the county auditor. The sheriff, with the approval of the board, may provide for the vocational training and rehabilitation of prisoners confined in the county jail.
