(a) Transfer. A person holding a position in the classified service may be transferred to a similar position in another department or division having the same pay and similar duties, but no transfer shall be made to a position requiring qualifications substantially different from those required in the position presently held, without the written consent of the person so transferred.
(b) Resignation. Any employee who has resigned in writing may, within thirty days thereafter, withdraw such resignation and be restored to the position vacated, if such position remains vacant or is filled by temporary appointment. If such position is not vacant, such person shall be placed on a reinstatement list for re-appointment to the class or position from which the resignation was made.
(c) Leave of Absence. The Mayor may grant a leave of absence to any person in the classified service for such period of time as the Mayor may determine, but in no event shall such period exceed one year, except that it enables such person to enter the service of the Armed Forces of the United States of America or other employment directly associated with the national defense, or is caused by reason of disability or injury received in the service of the City, or when such leave of absence is predicated upon the provisions of any disability benefit program or pension fund established for such person.
(d) Holding Position Open. Upon the expiration of a leave of absence, all persons in the classified service shall report to the Mayor and be reinstated in the position previously held.
(e) Absence Without Leave. Absence from duty of a person in the classified service without a leave being granted by authority of Section 135.19
(c), above, is neglect of duty, and good and sufficient cause for dismissal. Absence without leave, or permission, for three or more consecutive days shall be deemed a resignation from the service. Failure to report for duty after a leave of absence has expired is neglect of duty and good and sufficient cause for dismissal.
