Right-to-work laws are making a huge comeback, with five states passing legislation in the last five years. Later this month, New Hampshire could join that number, becoming the first state in the Northeast to prohibit workers from being required to support a union as a condition of employment.

Legislation already has passed the Granite State’s Senate, and its lower house is scheduled to vote on it Wednesday. Republican Gov. Chris Sununu has vowed to sign it if it lands on his desk.
