Section 860-D. Extension of mass layoff period

A mass layoff of more than
  six months which, at its outset, was announced to be a  mass  layoff  of
  six  months  or  less  shall be treated as an employment loss under this
  article unless:
    1. the extension beyond six months is caused by business circumstances
  (including unforeseeable  changes  in  price  or  cost)  not  reasonably
  foreseeable at the time of the initial mass layoff; and
    2.  notice is given at the time it becomes reasonably foreseeable that
  the extension beyond six months will be required.
