This Law Firm Publication by Jackson Lewis, P.C. discusses a recent decision by the Ohio Supreme Court holding that a worker is not required to prove he suffered a workplace injury to state a prima facie case of retaliation under Ohio's workers' compensation statute. The court's decision in Onderko v. Sierra Lobo, Inc. held that the statute's plain language only requires that the employee file or initiate a workers' compensation claim or testify in a workers' compensation proceeding in order to later pursue a retaliation claim.
