    This Act may be cited as the ``Preventing Labor Union Slowdowns Act 
of 2015'' or the ``PLUS Act''.

SEC. 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.'';
            (2) in section 2 (29 U.S.C. 152), by adding at the end the 
        following:
            ``(15) The term `employee engaged in maritime employment' 
        has the meaning given the term `employee' in section 2(3) of 
        the Longshore and Harbor Workers' Compensation Act (33 U.S.C. 
        902(3)).
            ``(16) The term `labor slowdown'--
                    ``(A) includes any intentional effort by employees 
                to reduce productivity or efficiency in the performance 
                of any duty of such employees; and
                    ``(B) does not include any such effort required by 
                the good faith belief of such employees that an 
                abnormally dangerous condition exists at the place of 
                employment of such employees.'';
            (3) in section 8(b) (29 U.S.C. 158(b)), by adding at the 
        end the following:
            ``(8) in representing, or seeking to represent, employees 
        engaged in maritime employment, to engage in a labor slowdown 
        at any time, including when a collective-bargaining agreement 
        is in effect.'';
            (4) in section 9 (29 U.S.C. 159), by adding at the end the 
        following:
    ``(f) Effect of Labor Slowdowns.--If a labor organization has been 
found, pursuant to a final order of the Board, to have violated section 
8(b)(8), the Board shall--
            ``(1) revoke the exclusive recognition or certification of 
        the labor organization, which shall immediately cease to be 
        entitled to represent the employees in the bargaining unit of 
        such labor organization; or
            ``(2) take other appropriate disciplinary action.''; and
            (5) in section 10(l) (29 U.S.C. 160(l)), in the first 
        sentence, by striking ``or section 8(b)(7)'' and inserting ``or 
        paragraph (7) or (8) of section 8(b)''.
    (b) Amendment to the Labor Management Relations Act, 1947.--Section 
303 of the Labor Management Relations Act, 1947 (29 U.S.C. 187) is 
amended--
            (1) in subsection (a), by striking ``in section 8(b)(4)'' 
        and inserting ``under paragraph (4) or (8) of section 8(b)'';
            (2) in subsection (b), by inserting ``, including 
        reasonable attorney fees for a violation under section 8(b)(8) 
        of the National Labor Relations Act (29 U.S.C. 158(b)(8))'' 
        before the period; and
            (3) by adding at the end the following:
    ``(c) In an action for damages resulting from a violation of 
section 8(b)(8) of the National Labor Relations Act (29 U.S.C. 
158(b)(8)), it shall not be a defense that the injured party has, in 
any manner, waived, or purported to waive, the right of such party to 
pursue monetary damages relating to the labor slowdown at issue--
            ``(1) in connection with a contractual grievance alleging a 
        violation of a clause prohibiting a strike, or a similar 
        clause, in a collective-bargaining agreement; or
            ``(2) in connection with an action for a breach of such a 
        clause under section 301.''.
Output: Preventing Labor Union Slowdowns Act of 2015 or the PLUS Act This bill amends the National Labor Relations Act and the Labor Management Relations Act, 1947 to make it an unlawful labor practice for a labor organization or its agents while representing, or seeking to represent, employees engaged in maritime employment to engage in a labor slowdown at any time, including when a collective-bargaining agreement is in effect. In cases where a labor organization has committed a violation, the National Labor Relations Board shall:  revoke the organization's exclusive recognition or certification to represent the employees in the bargaining unit, or take other appropriate disciplinary action.
