Mass. Gen. Laws ch. 150F § 3
TNDs shall have the right of self-organization, to form, join, or assist TND 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 by TNCs, and shall also have the right to refrain from any of these activities. Nothing contained in this chapter shall be interpreted to prohibit TNDs from exercising the right to confer with TNCs at any time, provided that during such conference there is no attempt by such TNC, directly or indirectly, to interfere with, restrain or coerce such workers in the exercise of the rights guaranteed by this section.
