704-B - Unfair Labor Practices.

* §  704-b.  Unfair  labor  practices.  1. It shall be an unfair labor
  practice for a farm laborer or  an  employee  organization  representing
  farm  laborers  to  strike  any agricultural employer. The term "strike"
  shall mean, for the purposes  of  this  section,  any  strike  or  other
  concerted stoppage of work or slowdown by farm laborers.
2.  It  shall be an unfair labor practice for an agricultural employer
  to:
a. lockout its laborers.  The  term  "lockout"  shall  mean,  for  the
  purposes  of  this  section,  a  refusal  by an agricultural employer to
  permit farm laborers to work as a result of a  dispute  with  such  farm
  laborers  or  employee organization representing such farm laborers that
  affects wages, hours and other terms and  conditions  of  employment  of
  such  farm laborers, provided, however, that a lockout shall not include
  a termination of employment for good cause that does  not  involve  such
  laborers exercising any rights guaranteed by this article;
b.  refuse  to  continue all the terms of an expired agreement until a
  new agreement is negotiated;
c. discourage union organization or to  discourage  an  employee  from
  participating  in  a  union  organizing  drive,  engaging  in  protected
  concerted activity, or otherwise exercising the rights guaranteed  under
  this article.
3. Nothing in this section shall be construed as to bar any proceeding
  brought  pursuant to section seven hundred four or seven hundred five of
  this article.
