The appointing authority may dismiss, suspend, reduce in step or demote any employee in the classified service provided the rules and regulations of the Civil Service Commission are followed. An employee may either appeal such dismissal, suspension or demotion to the Civil Service Commission or file a grievance in accordance with subsection 33.2. Appeal to the Civil Service Commission must be filed within the timelines established by the Commission rules. Grievances filed in accordance with subsection 33.2 must be filed within fourteen calendar days after receipt of written charges. No grievance involving demotion, suspension or dismissal of an employee will be entertained unless it is filed in writing with the Human Resources Director within 14 calendar days of the time at which the affected employee was notified of such action. An employee may not both appeal to the Civil Service Commission and file a grievance under subsection 33.2 of this MOU. A permanent classified employee may be dismissed, suspended or demoted for cause only.
