Under which act is the use of Yellow Dog contracts prohibited?

The use of Yellow Dog contracts is prohibited under the Norris-LaGuardia Act. This legislation was enacted in 1932 to limit the power of federal courts in labor disputes, particularly concerning the enforcement of agreements that required employees to abstain from union membership or participation as a condition of employment. The act aimed to protect workers' rights to organize and join labor unions without facing coercion or restriction from employers, making such contracts void and unenforceable.

Yellow Dog contracts were typically used by employers to discourage union organization by requiring employees to agree not to join or remain affiliated with a union. By prohibiting these contracts, the Norris-LaGuardia Act significantly strengthened workers' rights and supported the collective bargaining process.

The other acts mentioned have different focuses: the Davis-Bacon Act pertains to prevailing wage requirements for government contracts, the Taft-Hartley Act addresses union practices and employer-employee relations while also regulating union activities, and the Wagner Act is primarily focused on the rights of employees to organize and bargain collectively but does not specifically address Yellow Dog contracts.
