The mayor shall recommend revisions of these rules based on the needs of the city, applicable state and federal laws, and increased effectiveness. Recommendations to the council for action shall become effective upon approval of the council by ordinance. All revisions and amendments of this title apply to employees of the city as of the effective date of the amendments or revisions, unless specified otherwise in the ordinance implementing them. Employees hired prior to the effective date of amendments and revisions do not retain ongoing rights, privileges, or benefits that are rendered void or otherwise made unavailable by the amendment or revision. These provisions are intended to expressly preclude any implication or suggestion that “grandfather rights” are retained by employees hired prior to a revision or amendment of these personnel rules.
