Answer to Question 1
Sections 206 to 210 of the NLRA, which were added by the Taft-Hartley Act of 1947, provided for injunctions forestalling strikes when they threatened the national health or safety. The president is authorized to appoint a board of inquiry to report on the issues involved in the dispute, when a strike poses such a threat. The U.S. attorney general can secure an injunction to forestall the strike for up to 80 days, while the Federal Mediation and Conciliation Service attempts to resolve the dispute. The emergency provisions of the Taft-Hartley Act have been invoked only rarely in recent years. The emergency provisions allow the president to delay a strike but do not address the causes of the strike.
