Report the sexual harassment in accordance with your sexual harassment policy (in your employee handbook). You have a legal right to a harassment free workplace from everyone including individuals not employed by your employer. Make your report in writing. If nothing is done, or you are retaliated against, you may have a legal claim against your employer.   Ohio employment attorney www.mcoffmanlegal.com
