Which act aimed to restrict the power of unions and was passed in 1947?

The Taft-Hartley Act, passed in 1947, was designed to regulate labor unions and limit their power in various ways. This legislation emerged in response to growing concerns among politicians and business leaders about the increasing influence of unions in the post-World War II economy. The act included provisions that prohibited secondary boycotts, jurisdictional strikes, and closed shops, which were practices commonly employed by unions to strengthen their negotiating power. Additionally, it mandated that union leaders affirm they were not members of the Communist Party and required unions to provide financial transparency.

In contrast, the Wagner Act, also known as the National Labor Relations Act, aimed to protect the rights of workers to organize and engage in collective bargaining. It established the National Labor Relations Board to oversee labor relations and protect workers from unfair practices by employers. The Civil Rights Act does not pertain to labor unions, as it primarily addresses issues of discrimination based on race, color, religion, sex, or national origin in various aspects of public life. The National Labor Relations Act is another name for the Wagner Act and thus also does not pertain to the restrictions imposed by the Taft-Hartley Act.
