Date in History : September 14, 1959
The Labor-Management Reporting and Disclosure Act of 1959, also
known as the Landrum-Griffin Act, made major additions to the
Taft-Hartley Act, including:
(*) definition of additional unfair labor practices;
(*) a ban on organizational or recognition picketing;
(*) provisions allowing State labor relations agencies and courts to
assume jurisdiction over labor disputes the NLRB declined to
consider at the same time prohibiting the NLRB from broadening the
categories of cases it would not handle.
