In the U.S., any state law forbidding various union-security measures, particularly the union shop, under which workers are required to join a union within a specified time after they begin employment.
Supporters of such laws maintain that they are more equitable because they allow a person to choose whether or not to join a labour union . Opponents contend that the name right-to-work law is misleading because such laws do not guarantee employment to anyone. On the contrary, they maintain that such laws tend to reduce workers' job security by weakening the bargaining power of unions.
