N.Y.C. Admin. Code § 13-639: § 13-639 Board of estimate; authority to recommend retirement.

Any officer, whether appointed or elected, clerk or employee of any agency in the employ of the city or of any of the municipalities, counties or parts thereof which have been incorporated into the city and any officer, clerk or employee whose salary or compensation is a county charge who shall have been employed for a period of thirty years and upwards and who shall have become physically or mentally incapacitated for the further performance of the duties of his or her position, may be recommended for retirement from active service to the board of estimate by any member thereof whenever, in his or her judgment, it shall be to the interest of the public service. The term of service, however, shall not be affected by any change in title, duty or salary or by any promotion or by a vacation or leave of absence or by any temporary disability by reason of sickness or accident or by any transfer from one agency to another during the period of service, or by any change of any of the agencies in which service shall have been performed from an office paid by fees to a salaried office.
