Which Act specifically prohibited Federal courts from enforcing 'yellow dog' contracts or restraining orders against activities by labor unions and individuals?

• A. Wagner Act
• B. Americans with Disabilities Act
• C. Fair Labor Standards Act
• D. Norris-LaGuardia Act

Answer: (D)

The key idea here is the protection of workers’ rights to organize and engage in peaceful union activity by limiting the power of the courts in labor disputes. The Norris-LaGuardia Act specifically barred federal courts from issuing or enforcing injunctions in non-violent labor disputes and outlawed yellow-dog contracts, which forced workers to promise not to join a union as a condition of employment. By removing court power to restrain union activity in these cases, it gave workers greater freedom to organize without immediate Supreme Court-style intervention for employers. The other acts address different issues: the Wagner Act later strengthens collective bargaining rights and creates the National Labor Relations Board; the Americans with Disabilities Act protects disability rights; the Fair Labor Standards Act sets wage and hour rules. So the act that matches the description is the Norris-LaGuardia Act.
