Right-to-work laws are statutes enforced in twenty-two U.S. states, mostly in the southern or western U.S., allowed under provisions of the Taft-Hartley Act, which prohibit agreements between trade unions and employers making membership or payment of union dues or "fees" a condition of employment, either before or after hiring.
Right to work endangers safety and health standards that protect workers on the job by weakening unions that help to ensure worker safety by fighting for tougher safety rules.
According to the federal Bureau of Labor Statistics, the rate of workplace deaths is 51 percent higher in states with right to work, where unions can’t speak up on behalf of workers
