Ohio Rev. Code § 3319.086
In all school districts, forty hours shall be the standard work week for all non-teaching school employees. Such employees shall not be required to work on days declared by the employing board of education as school holidays unless failure to work on such holidays would impair the public service. Where such employees are required by their responsible administrative superiors to work in excess of forty hours in any seven day period or to work on days declared by the employing board of education to be school holidays, they shall be compensated for such time worked at not less than their regular rate of pay, or be granted compensatory time off. As used in this section, "non-teaching school employees" does not include any person employed in the public schools of the state in an administrative or supervisory capacity in connection with the services rendered by non-teaching school employees.
Nothing in this section shall prevent the school district from establishing a work week of less than forty hours.
