Note: The coverage rate in neighboring RTW states is calculated by averaging the coverage rate in each state. Neighboring RTW states are Idaho, South Dakota, and Wyoming.

"Coverage rates" are the share of workers covered by a collective bargaining contract.

So-called right-to-work (RTW) laws make it illegal for a group of unionized workers to negotiate a collective bargaining contract (a contract governing workplace wages, benefits, and working conditions) that includes “fair share fees.” A contract with fair share fees requires all employees who enjoy the contract’s benefits to pay their share of the costs of negotiating and enforcing it.
