Ohio Rev. Code § 4123.90
The bureau of workers' compensation, industrial commission, or any other body constituted by the statutes of this state, or any court of this state, in awarding compensation to the dependents of employees, or others killed in Ohio, shall not make any discrimination against the widows, children, or other dependents who reside in a foreign country. The bureau, commission, or any other board or court, in determining the amount of compensation to be paid to the dependents of killed employees, shall pay to the alien dependents residing in foreign countries the same benefits as to those dependents residing in this state.
No employer shall discharge, demote, reassign, or take any punitive action against any employee because the employee filed a claim or instituted, pursued or testified in any proceedings under the workers' compensation act for an injury or occupational disease which occurred in the course of and arising out of his employment with that employer. Any such employee may file an action in the common pleas court of the county of such employment in which the relief which may be granted shall be limited to reinstatement with back pay, if the action is based upon discharge, or an award for wages lost if based upon demotion, reassignment, or punitive action taken, offset by earnings subsequent to discharge, demotion, reassignment, or punitive action taken, and payments received pursuant to section 4123.56 and Chapter 4141. of the Revised Code plus reasonable attorney fees. The action shall be forever barred unless filed within one hundred eighty days immediately following the discharge, demotion, reassignment, or punitive action taken, and no action may be instituted or maintained unless the employer has received written notice of a claimed violation of this paragraph within the ninety days immediately following the discharge, demotion, reassignment, or punitive action taken.
