Okla. Admin. Code § 260:130-27-5
The Civil Service Division shall establish and maintain standards of progressive discipline that shall be followed by all Appointing Authorities unless the Appointing Authority has received an exemption from the Civil Service Division from the standards. In order to request an exemption from the standards, the Appointing Authority must provide the Civil Service Division with a progressive discipline plan the Appointing Authority will follow in lieu of the standards. The Civil Service Division will review the exemption request and notify the requesting Appointing Authority in writing whether the request has been approved or denied. The standards can be found on the website maintained by the Civil Service Division. The progressive discipline standards shall not be required for employee separations that occur as a result of voluntary buy outs or reductions-in-force as set forth in the applicable Oklahoma statutes.
