Ohio Rev. Code § 2151.211
No employer shall discharge or terminate from employment, threaten to discharge or terminate from employment, or otherwise punish or penalize any employee because of time lost from regular employment as a result of the employee's attendance at any proceeding pursuant to a subpoena under this chapter or Chapter 2152. of the Revised Code. This section generally does not require and shall not be construed to require an employer to pay an employee for time lost as a result of attendance at any proceeding under either chapter. However, if an employee is subpoenaed to appear at a proceeding under either chapter and the proceeding pertains to an offense against the employer or an offense involving the employee during the course of the employee's employment, the employer shall not decrease or withhold the employee's pay for any time lost as a result of compliance with the subpoena. Any employer who knowingly violates this section is in contempt of court.
