What effect did the Taft hartley act have on the closed shop?

The Taft-Hartley Act of 1947 significantly restricted the closed shop arrangement, which required employers to hire only union members. The Act prohibited closed shops and allowed states to pass "right-to-work" laws, enabling workers to choose whether or not to join a union without facing mandatory membership. This legislation aimed to balance the power between labor unions and employers, ultimately reducing union influence in the workplace.
