Section 48-C. Assignment of future earnings by person unemployed; effect of loss of employment

If the assignor is not employed at the time he makes
  an assignment of future earnings, but is thereafter employed, his future
  earnings shall  nevertheless  become  collectible  by  the  assignee  as
  provided  in  this  article  upon the filing of the prescribed documents
  with the employer. No assignment of future earnings shall become invalid
  by reason of the cessation of employment, or  cessation  of  payment  of
  earnings,  but  shall  continue  in  effect,  and  may be applied to the
  payment of any future earnings from the same  or  other  employment,  in
  accordance  with  the  provisions  of  this  article,  so  long  as  the
  indebtedness secured by the assignment shall remain unpaid in  whole  or
  in  part. If the assignor is re-employed by the same employer before the
  expiration of ninety  days  from  the  termination  of  employment,  the
  assignment  shall  continue  to be collectible without further filing of
  papers. If the employee is re-employed on or  after  the  expiration  of
  such ninety days, the assignment shall again become collectible from the
  employer  as  provided in section forty-eight-a only after copies of the
  assignment and the other documents specified in such section  have  been
  filed with the employer following the re-employment.
