Ohio Rev. Code § 345.16: Employment of veterans.

The board of trustees, for soldiers' memorials under its control, shall employ only honorably discharged soldiers, sailors, and marines, both men and women, of the armed forces of the United States, if available, as caretakers, janitors, or employees.

Employment of any person who is not such an honorably discharged soldier, sailor, or marine, without a showing on the journal of the board that none of the latter were available, shall be void, and it shall be unlawful to pay any money out of any fund to such person.
