1. Short title This Act may be cited as the Preventing Labor Union Slowdowns Act of 2017 or the PLUS Act . 2. Deterring labor slowdowns (a) Amendments to the National Labor Relations Act The National Labor Relations Act is amended— (1) in section 1 ( 29 U.S.C. 151 ), by adding at the end the following: International trade is one of the most important components of the economy of the United States and will likely continue to grow in the future. In order to remain competitive in an increasingly competitive global economy, it is essential that the United States possess a highly efficient and reliable public and private transportation network. The ports of the United States are an increasingly important part of such transportation network. Experience has demonstrated that frequent and periodic disruptions to commerce in the maritime industry in the form of deliberate and unprotected labor slowdowns at the ports of the United States have led to substantial and frequent economic disruption and loss, interfering with the free flow of domestic and international commerce and threatening the economic health of the United States, as well as its citizens and businesses. Such frequent and periodic disruptions to commerce in the maritime industry hurt the reputation of the United States in the global economy, cause the ports of the United States to lose business, and represent a serious and burgeoning threat to the financial health and economic stability of the United States. It is hereby declared to be the policy of the United States to eliminate the causes and mitigate the effects of such disruptions to commerce in the maritime industry and to provide effective and prompt remedies to individuals injured by such disruptions.
