Right-to-work laws prevent workers’ money from being spent on political activity
Unions cannot force members to pay for their political activity
Workers can opt out of full union membership to prevent their money from being spent on political activity. The National Labor Relations Board (NLRB) explains that workers do not have to be full union members, but instead must only pay for the union representation they receive by working at a union shop, regardless of their membership status:
The NLRA allows employers and unions to enter into union-security agreements, which require all employees in a bargaining unit to become union members and begin paying union dues and fees within 30 days of being hired.
Even under a security agreement, employees who object to full union membership may continue as 'core' members and pay only that share of dues used directly for representation, such as collective bargaining and contract administration. Known as objectors, they are no longer full members but are still protected by the union contract. Unions are obligated to tell all covered employees about this option, which was created by a Supreme Court ruling and is known as the Beck right.
