I. Any employer who fails to give notice under N.H. Rev. Stat. § 275-F:3 before ordering a mass layoff or plant closing is liable to each employee entitled to notice who lost his or her employment for:
(a) Back pay at the average regular rate of compensation received by the employee during the last 3 years of his or her employment, or the employee’s final rate of compensation, whichever is higher.
(b) The value of the cost of any benefits to which the employee would have been entitled had his or her employment not been lost, including the cost of any medical expenses incurred by the employee that would have been covered under an employee benefit plan.
(c) Costs and reasonable attorney’s fees.

Stat. § 545-A:5, as applicable, and shall have the remedies set forth in N.H. Rev. Stat. Chapter 545-A for such claims under N.H. Rev. Stat. Chapter 545-A which are established by the state.
IX. An action to recover the back pay, benefits, costs, and attorneys fees and other moneys for which an employer may be liable under this chapter may be maintained against any employer by any one or more employees for and on behalf of the employee and any other employees similarly situated.
