2006 New York Code - Membership Classification.

 
    §  13-106  Membership  classification.  a. It shall be the duty of the
  head of each agency to submit to such  board  a  statement  showing  the
  name,   title,  compensation,  duties,  date  of  birth  and  length  of
  city-service of each member and such other information as such board may
  require. If such member be principally  engaged  upon  duties  differing
  from  those specified by the appropriate civil service commission, state
  or municipal, for the title held by such member,  such  head  of  agency
  shall  certify  the reasons therefor and the probable duration of duties
  by such member differing from those  specified  by  such  civil  service
  commission  for  the  title  held  by such member. Such board shall then
  classify the member in one of the following groups:
    1. Group one: Laborers  and  unskilled  workers  engaged  upon  duties
  requiring principally physical exertion;
    2.  Group  two:  Mechanics  and  skilled  workers  engaged upon duties
  requiring principally physical exertion;
    3. Group three: Clerical, administrative, professional  and  technical
  workers  engaged  upon  duties  requiring  principally  mental exertion,
  including heads of departments;
    4. Group four: In any other group of not less than twenty-five hundred
  members which, on the basis of mortality or service experience,  may  be
  recommended by the actuary and established by such board.
    b.  Such  board  shall certify to such member the group in which he or
  she has been placed and the date of his or her admission  to  membership
  therein. When the duties of a member so require, such board may classify
  him  or  her in another group and transfer such member thereto and shall
  thereupon certify to him or her the group to which he or  she  has  been
  transferred and the date of his or her transfer thereto.
    c.  Each  member  shall  be  subject,  until  retirement,  to  all the
  provisions of this chapter and to all the rules and regulations  adopted
  by such board applying to his or her group.
