Which act forbid yellow-dog contracts and restricted courts' rights to issue injunctions?

The Norris-La Guardia Act is the correct answer because it specifically prohibits yellow-dog contracts, which are agreements that employers use to restrict workers from joining unions or engaging in collective bargaining. This act was revolutionary in labor relations as it aimed to protect workers’ rights to organize and participate in union activities without facing penalties from employers.

Moreover, the act restricted the ability of federal courts to issue injunctions in labor disputes, meaning that judges could not interfere in union activities or labor strikes unless there was a clear and present danger of physical harm. This limitation on judicial intervention was critical in supporting labor rights during a time when such protections were necessary for the empowerment of workers.

In contrast, the Fair Labor Standards Act primarily focuses on establishing minimum wage, overtime pay, and child labor standards, without addressing yellow-dog contracts or judicial injunctions. The National Labor Relations Act is crucial for establishing the rights of employees to unionize, but it does not specifically include provisions against yellow-dog contracts. The Labor Management Relations Act, also known as the Taft-Hartley Act, amended the National Labor Relations Act and addressed union practices in a different context, but it is the Norris-La Guardia Act that directly outlaws yellow-dog contracts and limits injunctions regarding labor disputes
