A yellow-dog contract (a yellow-dog clause of a contract, also known as an ironclad oath)[1] is an agreement between an employer and an employee in which the employee agrees, as a condition of employment, not to be a member of a labor union.[2] In the United States, such contracts were used by employers to prevent the formation of unions, most often by permitting employers to take legal action against union organizers.[3] In 1932, yellow-dog contracts were outlawed in the United States under the Norris-LaGuardia Act.[4][5]
