Section 130-A. Declaration of policy

The legislature hereby determines
  that (1) employees of the state and its  political  subdivisions,  their
  survivors  and dependents, are entitled to the basic protection provided
  by  the  federal  old-age  and  survivors  insurance  system,  (2)  such
  protection  should be provided to as many of such employees as possible,
  regardless of whether they are or are not members of public  pension  or
  retirement   systems   maintained   by   the   state  or  its  political
  subdivisions, with the option to those who are presently  members  of  a
  retirement  system  to have or not to have such additional protection as
  they so desire, (3) such extension of old-age  and  survivors  insurance
  coverage to public employees in this state is consistent with principles
  of  sound  employer-employee  relations,  (4) provision of such coverage
  will provide not only basic security  to  present  employees  and  their
  dependents,  but  also  will  serve  to attract competent persons to the
  employ of the state and  its  political  subdivisions  who  now  may  be
  discouraged  from  accepting  such employment by reason of the fact that
  their old-age and survivors insurance coverage obtained through  private
  or  self  employment  would  not  be  continued,  and (5) the protection
  afforded to employees in positions covered by any retirement  system  in
  the  state  on  the  date  old-age  and  survivors insurance coverage is
  extended to their positions will not be impaired as the result  of  such
  extension  of  coverage  or  as  the  result of legislative enactment in
  anticipation thereof.
