If an employer has 50 or more employees and sponsors family and medical leave insurance pursuant to N.H. Rev. Stat. § 21-I:99, then any employee of that employer who takes family or medical leave and accesses wage replacement benefits under such family and medical leave insurance coverage shall be restored to the position she or he held prior to such leave or to an equivalent position by her or his employer consistent with the job restoration provisions of the federal Family and Medical Leave Act of 1993, Public Law 103-3, 29 U.S.C. § 2601 et seq. Such employers shall continue to provide health insurance to employees during the leave. However, employees shall remain responsible for any employee-shared costs associated with the health insurance benefits. Such employers shall not discriminate or retaliate against any employee for accessing family or medical leave wage replacement benefits. Employers of employees participating in the granite state paid family leave plan may require that paid leave taken under this program be taken concurrently or otherwise coordinated with leave allowed under the terms of a collective bargaining agreement or other established employer policy or the Family and Medical Leave Act, as applicable. In addition, the commissioner may adopt rules under N.H. Rev. Stat. Chapter 541-A to facilitate administration and enforcement of this section.
