N.Y. Lab. Law § 703
Employees shall have the right of self-organization, to form, join, or assist labor organizations, to bargain collectively through representatives of their own choosing, and to engage in concerted activities, for the purpose of collective bargaining or other mutual aid or protection, free from interference, restraint, or coercion of employers, but nothing contained in this article shall be interpreted to prohibit employees from exercising the right to confer with their employer at any time, provided that during such conference there is no attempt by the employer, directly or indirectly, to interfere with, restrain or coerce employees in the exercise of the rights guaranteed by this section.
Notwithstanding any other provision of law, for farm laborers the term "concerted activities" shall not include a right to strike or other concerted stoppage of work or slowdown.
