Many states and local governments are considering right-to-work laws. These laws make union dues voluntary. Without them, union contracts make paying dues a condition of employment.

While most Americans support the concept of right-to-work, unions argue strenuously against them. However, most of the arguments against right-to-work have little basis in fact.

Myth: Right-to-work laws prohibit unions.

Fact: Right-to-work laws make union dues voluntary. Without right-to-work laws, unions negotiate contracts that force workers to pay dues or get fired. Right-to-work laws protect workers' freedom. The National Labor Relations Act also protects the right of workers in right-to-work states to unionize. Unions currently represent 4.4 million workers in 24 right-to-work states.

Myth: Right-to-work laws undermine unions.

Fact: Right-to-work laws make unions work to earn workers' support. In the long run, this can strengthen union locals. Without right-to-work laws, unions can take their members' dues for granted and provide lower quality representation.

Myth: Right-to-work laws allow nonunion members to "free ride" on the benefits of union representation without paying its cost.

Fact: The Supreme Court repeatedly has ruled that the National Labor Relations Act allows unions to negotiate contracts covering only dues-paying members. Unions represent non-members only when they act as "exclusive bargaining representatives," which requires non-members to accept the union's representation.

In that case, the law requires unions to represent non-members fairly. They cannot negotiate high wages for their supporters and the minimum wage for non-members. Unions can avoid representing non-members by disclaiming exclusive representative status.

Myth: Representing non-members costs exclusive representative unions a lot of money.

Fact: Unions often spend little on representational activities. When unions choose to act as exclusive bargaining representatives, they often spend relatively little on processing grievances and negotiating contracts. Often union contracts have employers cover these costs by allowing union stewards to do union business while on company time. As a result, many union locals spend very little representing workers — either members or non-members.

Myth: Right-to-work laws provide no economic benefits.

Fact: Companies consider right-to-work laws a major factor when deciding where to locate

. Economic development consultants report that roughly half of all major businesses refuse to consider locating in jurisdictions with compulsory dues. Bureau of Labor Statistics data show that between 1990 and 2014 total employment grew more than twice as fast in right-to-work states as in states with compulsory dues.

Myth: Right-to-work laws lower wages.

Fact: Average wages in right-to-work states are indeed slightly lower than in non-right-to-work states. This occurs because almost every Southern state has a right-to-work law, and the South has a lower cost of living. Studies that control for differences in costs of living find workers in states with voluntary dues have no lower — and possibly slightly higher — real wages than workers in states with compulsory dues.
