SECTION 1. Chapter 149 of the General Laws is hereby amended by adding the following section:-

Section 189. A provision in any contract waiving any substantive or procedural right or remedy relating to a claim of discrimination, non-payment of wages or benefits, retaliation, harassment or violation of public policy in employment shall be deemed unconscionable, void and unenforceable, with respect to any such claim arising after the waiver is made. No right or remedy arising under this section, this chapter, Chapter 151B, common law, any other provision of law or rule of procedure or the constitution shall be prospectively waived.  This section shall not render void or unenforceable the remainder of the contract or agreement. 

Whoever enforces or attempts to enforce a waiver deemed unconscionable, void or unenforceable under this section shall be liable for reasonable attorneys fees and costs.

No person or employer shall take any retaliatory action, including, but not limited to, failure to hire, discharge, suspension, demotion, discrimination in the terms, conditions or privileges of employment, or other adverse action, against a person, because the person does not enter into an agreement or contract that contains a waiver deemed unconscionable, void or unenforceable under this section. A person aggrieved of a violation of this section may, within 3 years after the violation, institute and prosecute in such person’s own name and on such person’s own behalf a civil action for “torts remedies,” for injunctive relief, and for the costs of litigation and reasonable attorneys' fees. The rights and remedies contained in this section shall not be exclusive and shall not preempt other available procedures and remedies for retaliatory actions, including, without limitation, those contained in section 4 of chapter 151B and section 150 of chapter 149.

The Massachusetts attorney general may enforce this section when the substantive or procedural right or remedy at issue arises under section 150 of chapter 149. 

The Massachusetts Commission Against Discrimination may enforce this section when the substantive or procedural right or remedy at issue arises under Chapter 151B.

A person aggrieved of a violation under chapter 151B who seeks a remedy that is not (i) non-enforcement of a provision prohibited by this section or (ii) reasonable attorneys' fees and costs for enforcement of a provision prohibited by this section, shall seek such remedy under chapter 151B Nothing in this section shall expand or limit the use of collective bargaining agreements.

SECTION 2. This act shall apply to all agreements entered into on or after the effective date of this act.
