Every employment relationship is a contractual one, regardless of whether or not a written contract exists. Employment contracts take many forms, including at-will employment, implied contracts created by offer letters or employee handbooks, collective bargaining agreements, and individual written employment agreements.
The default rule in Ohio is employment at will. This means that both the employee and employer are generally free to terminate the employment relationship at any time and for any reason, as long as the reason is not illegal or in violation of public policy. While there is a strong presumption in favor of at-will employment in Ohio, the courts have recognized exceptions in some circumstances.
