How did the Taft-Hartley Act of 1947 affect labor?

The Taft-Hartley Act of 1947 significantly impacted labor by curbing the powers of labor unions and placing restrictions on their activities. It prohibited secondary boycotts, closed shops, and jurisdictional strikes, while also allowing states to pass right-to-work laws that made union membership optional for workers. The Act aimed to balance the interests of labor and management, leading to increased tensions between unions and employers. Overall, it marked a shift toward limiting union influence in the post-World War II labor landscape.
