What does the Clayton Act prohibit with respect to unions?

The Clayton Act, enacted in 1914, primarily addresses antitrust laws and aims to protect the rights of labor unions and the right of individuals to organize. However, it does not prohibit the formation of labor organizations. Instead, the Clayton Act specifically protects the activities of labor unions. It ensures that the courts recognize the legality of strikes, picketing, and other forms of union activity during collective bargaining.

The correct interpretation aligns with the aim of the Clayton Act to bolster union activities and their existence rather than prohibit them. The Act was designed to counteract the effects of antitrust laws that could restrict labor unions by affirming their right to organize and collectively negotiate. Thus, it allows for the formation of labor organizations and is not an avenue for imposing restrictions on them.

On the other hand, the other options relate to different aspects of union activities that the law addresses, such as interference with elections or discrimination against union members, which are regulated under other labor laws such as the National Labor Relations Act, but are not directly prohibited by the Clayton Act itself.
