Taft-Hartley Definition: The name of an American federal labor law which was passed in 1947, and which sought to equalize legal responsibilities of labor organizations and employers; ie. balance the Wagner Act, which, it was felt, may have gone to far in protecting union rights. Where the Wagner Act had was aimed primarily at employer behavior, the Taft-Hartley was aimed at unions and sought to restrain their activities under certain circumstances, by detailing union rights and duties. For example, the Taft-Hartley Act exempted supervisors from it’s provisions, allowed employees to decline participation in union activities and permitted union decertification petitions.
