Missouri
Missouri became a right-to-work state in 2017 but voters repealed the law via referendum in 2018 — Missouri is not right-to-work. Electrical contractors are licensed at the state level through the Office of Statewide Electrical Contractors (Division of Professional Registration). Plumbing and HVAC licensing is primarily managed at the city and county level.
