Article 20 - (Labor) NEW YORK STATE LABOR RELATIONS ACT
713 - Limitations.

  713.  Limitations. Nothing in this article shall be construed so as
  to interfere with, impede or diminish in any way the right of  employees
  to  strike  or engage in other lawful, concerted activities, except that
  it shall continue to be unlawful for the employees of a non-profitmaking
  hospital or residential care center, or their  representatives,  or  any
  other  persons  to engage in or to induce or encourage, or to attempt to
  engage in or to induce or encourage any strike, work stoppage,  slowdown
  or  withholding  of goods or services by such employees or other persons
  at such hospital or residential care  center,  provided,  however,  that
  nothing  herein  shall  be  construed  to prohibit publicity, other than
  picketing, for the purpose of truthfully  advising  the  public  that  a
  grievance  or  dispute,  as  defined in section seven hundred sixteen of
  this article, exists at such hospital or  residential  care  center,  as
  long  as such publicity does not have the effect of inducing any persons
  to withhold goods or services  at  such  hospital  or  residential  care
  center.
It  shall  be  unlawful for a non-profitmaking hospital or residential
  care center to institute, declare or cause, or to attempt to  institute,
  declare  or  cause  any  lockout  of  the  employees of such hospital or
  residential care center.
