(Right-to-Work Law), according to Wikipedia:

A "right-to-work" law is a US law that prohibits union security agreements, or agreements between labor unions and employers, that govern the extent to which an established union can require employees' membership, payment of union dues, or fees as a condition of employment, either before or after hiring. Right-to-work laws are a government regulation of contractual agreements between employers and labor unions that prevents employers from excluding non-union workers or requiring employees to pay a fee to the unions that negotiated the labor contract under which all employees work.

Not all unions support "right-to-work" legislation, which is perhaps unsurprising. The AFL-CIO (Right to Work) states, for example:

Through "right to work" laws, extremist groups, right-wing politicians, and their corporate backers hope to weaken the power of workers and unions. Their actions are a partisan political stunt that jeopardizes workers' fundamental rights. These laws reduce wages and living standards for all state employees by weakening unions. Workers in these states earn $5,680 less per year on average than workers in other states. Working families in states without these laws benefit from healthier tax bases, which improve their quality of life, as a result of their higher wages.

Do you think right-to-work legislation is beneficial? Is there any reason to believe that? Are you in agreement with the AFL-assessment CIO's of right-to-work legislation? Is there any reason to believe that? What are your thoughts on unions and union membership (positive, negative, or neutral)?
