NORRIS-LAGUARDIA ACT: A Congressional act passed in 1932 that outlawed the use of yellow-dog contracts by employers and made it more difficult for firms to use legal injunctions against labor unions. This act strengthened labor related provisions of the Clayton Act and foreshadowed the more favorable attitude toward labor unions under the ensuing Roosevelt administration.
