What is a Yellow Dog Contract?

Yellow Dog Contract definition

Yellow dog contracts also called "yellow-dog clauses" or "ironclad oaths", are cases where employees agree, as part of their employment conditions, not to join union relations or become a member of a union.

When were Yellow Dog Contracts used?

Yellow Dog Contracts were used widely until the 1930s as a strategy to prevent organised union protests and offered a way for companies to chase union organisers in a legal way.

However, since 1932, yellow-dog contracts are not implementable backing the passing of the Norris-LaGuardia Act (Section 3) in that same year.

When did the term “Yellow Dog” appear?

The word ‘yellow dog’ began to emerge in the 1920s as a comparison for what any person signing it would lessen themselves too by forgoing significant constitutional rights.
