N.H. Rev. Stat. Ann. § 98-E:1

Notwithstanding any other rule or order to the contrary, a person employed as a public employee in any capacity shall have a full right to publicly discuss and give opinions as an individual on all matters concerning any government entity and its policies. It is the intention of this chapter to balance the rights of expression of the employee with the need of the employer to protect legitimate confidential records, communications, and proceedings.
