What does a Yellow Dog contract prohibit?

A Yellow Dog contract is a type of employment agreement that prohibits workers from joining a labor union as a condition of their employment. This kind of contract aims to weaken labor unions by ensuring that employees cannot organize or collectively bargain, effectively reducing their bargaining power. By requiring job applicants to agree not to join a union, the employer seeks to maintain control over the workforce and limit union influence within the company.

This form of contract was more common during the early to mid-20th century but has largely been deemed unlawful in many jurisdictions due to legislation that protects the right to organize and engage in collective bargaining. The historical context around Yellow Dog contracts highlights the tensions between labor rights and employer interests, emphasizing the importance of understanding labor law in the field of contracting and employment.
