Labor Management Relations Act (1947)

An Act To amend the National Labor Relations Act, to provide additional facilities for the mediation of labor disputes affecting commerce, to equalize legal responsibilities of labor organizations and employers, and for other purposes.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,

Short Title and Declaration of Policy

Section 1. (a) This Act may be cited as the "Labor Management Relations Act, 1947".

(b) Industrial strife which interferes with the normal flow of commerce and with the full production of articles and commodities for commerce, can be avoided or substantially minimized if employers, employees, and labor organizations each recognize under law one another's legitimate rights in their relations with each other, and above all recognize under law that neither party has any right in its relations with any other to engage in acts or practices which jeopardize the public health, safety, or interest.

It is the purpose and policy of this Act, in order to promote the full flow of commerce, to prescribe the legitimate rights of both employees and employers in their relations affecting commerce, to provide orderly and peaceful procedures for preventing the interference by either with the legitimate rights of the other, to protect the rights of individual employees in their relations with labor organizations whose activities affect commerce, to define and proscribe practices on the part of labor and management which affect commerce and are inimical to the general welfare, and to protect the rights of the public in connection with labor disputes affecting commerce.

Title I—Amendment of National Labor Relations Act

Sec. 101. The National Labor Relations Act is hereby amended to read as follows:

Findings and Policies

Section 1. The denial by some employers of the right of employees to organize and the refusal by some employers to accept the procedure of collective bargaining lead to strikes and other forms of industrial strife or unrest, which have the intent or the necessary effect of burdening or obstructing commerce by (a) impairing the efficiency, safety, or operation of the instrumentalities of commerce; (b) occurring in the current of commerce; (c) materially affecting, restraining, or controlling the flow of raw materials or manufactured or processed goods from or into the channels of commerce, or the prices of such materials or goods in commerce; or (d) causing diminution of employment and wages in such volume as substantially to impair or disrupt the market for goods flowing from or into the channels of commerce.

The inequality of bargaining power between employees who do not possess full freedom of association or actual liberty of contract, and employers who are organized in the corporate or other forms of ownership association substantially burdens and affects the flow of commerce, and tends to aggravate recurrent business depressions, by depressing wage rates and the purchasing power of wage earners in industry and by preventing the stabilization of competitive wage rates and working conditions within and between industries.

Experience has proved that protection by law of the right of employees to organize and bargain collectively safeguards commerce from injury, impairment, or interruption, and promotes the flow of commerce by removing certain recognized sources of industrial strife and unrest, by encouraging practices fundamental to the friendly adjustment of industrial disputes arising out of differences as to wages, hours, or other working conditions, and by restoring equality of bargaining power between employers and employees.

Experience has further demonstrated that certain practices by some labor organizations, their officers, and members have the intent or the necessary effect of burdening or obstructing commerce by preventing the free flow of goods in such commerce through strikes and other forms of industrial unrest or through concerted activities which impair the interest of the public in the free flow of such commerce. The elimination of such practices is a necessary condition to the assurance of the rights herein guaranteed.

It is hereby declared to be the policy of the United States to eliminate the causes of certain substantial obstructions to the free flow of commerce and to mitigate and eliminate these obstructions when they have occurred by encouraging the practice and procedure of collec- tive bargaining and by protecting the exercise by workers of full freedom of association, self-organization, and designation of representatives of their own choosing, for the purpose of negotiating the terms and conditions of their employment or other mutual aid or protection. . . . 

National Labor Relations Board

Sec. 3. (a) The National Labor Relations Board (hereinafter called the ‘Board’) created by this Act prior to its amendment by the Labor Management Relations Act, 1947, is hereby continued as an agency of the United States, except that the Board shall consist of five instead of three members, appointed by the President by and with the advice and consent of the Senate. Of the two additional members so provided for, one shall be appointed for a term of five years and the other for a term of two years. Their successors, and the successors of the other members, shall be appointed for terms of five years each, excepting that any individual chosen to fill a vacancy shall be appointed only for the unexpired term of the member whom he shall succeed. The President shall designate one member to serve as Chairman of the Board. Any member of the Board may be removed by the President, upon notice and hearing, for neglect of duty or malfeasance in office, but for no other cause.

(b) The Board is authorized to delegate to any group of three or more members any or all of the powers which it may itself exercise. A vacancy in the Board shall not impair the right of the remaining members to exercise all of the powers of the Board, and three members of the Board shall, at all times, constitute a quorum of the Board, except that two members shall constitute a quorum of any group designated pursuant to the first sentence hereof. The Board shall have an official seal which shall be judicially noticed.

(c) The Board shall at the close of each fiscal year make a report in writing to Congress and to the President stating in detail the cases it has heard, the decisions it has rendered, the names, salaries, and duties of all employees and officers in the employ or under the supervision of the Board, and an account of all moneys it has disbursed.

(d) There shall be a General Counsel of the Board who shall be appointed by the President, by and with the advice and consent of the Senate, for a term of four years. The General Counsel of the Board shall exercise general supervision over all attorneys employed by the Board (other than trial examiners and legal assistants to Board members) and over the officers and employees in the regional offices. He shall have final authority, on behalf of the Board, in respect of the investigation of charges and issuance of complaints under section 10, and in respect of the prosecution of such complaints before the Board, and shall have such other duties as the Board may prescribe or as may be provided by law.

Sec. 4. (a) Each member of the Board and the General Counsel of the Board shall receive a salary of $12,000 a year, shall be eligible for reappointment, and shall not engage in any other business, vocation, or employment. The Board shall appoint an executive secretary, and such attorneys, examiners, and regional directors, and such other employees as it may from time to time find necessary for the proper performance of its duties. The Board may not employ any attorneys for the purpose of reviewing transcripts of hearings or preparing drafts of opinions except that any attorney employed for assignment as a legal assistant to any Board member may for such Board member review such transcripts and prepare such drafts. No trial examiner’s report shall be reviewed, either before or after its publication, by any person other than a member of the Board or his legal assistant, and no trial examiner shall advise or consult with the Board with respect to exceptions taken to his findings, rulings, or recommendations. The Board may establish or utilize such regional, local, or other agencies, and utilize such voluntary and uncompensated services, as may from time to time be needed. Attorneys appointed under this section may, at the direction of the Board, appear for and represent the Board in any case in court. Nothing in this Act shall be construed to authorize the Board to appoint individuals for the purpose of conciliation or mediation, or for economic analysis.

(b) All of the expenses of the Board, including all necessary traveling and subsistence expenses outside the District of Columbia incurred by the members or employees of the Board under its orders, shall be allowed and paid on the presentation of itemized vouchers therefor approved by the Board or by any individual it designates for that purpose.

Sec. 5. The principal office of the Board shall be in the District of Columbia, but it may meet and exercise any or all of its powers at any other place. The Board may, by one or more of its members or by such agents or agencies as it may designate, prosecute any inquiry necessary to its functions in any part of the United States. A member who participates in such an inquiry shall not be disqualified from subsequently participating in a decision of the Board in the same case.

Sec. 6. The Board shall have authority from time to time to make, amend, and rescind, in the manner prescribed by the Administrative Procedure Act, such rules and regulations as may be necessary to carry out the provisions of this Act.

Rights of Employees

Sec. 7. Employees shall have the right to self-organization, to form, join, or assist labor organizations, to bargain collectively through representatives of their own choosing, and to engage in other concerted activities for the purpose of collective bargaining or other mutual aid or protection, and shall also have the right to refrain from any or all of such activities except to the extent that such right may; be affected by an agreement requiring membership in a labor organization as a condition of employment as authorized in section 8 (a) (3).

Unfair Labor Practices

Sec. 8. (a) It shall be an unfair labor practice for an employer—

     (1) to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in section 7;

     (2) to dominate or interfere with the formation or administration of any labor organization or contribute financial or other support to it: Provided, That subject to rules and regulations made and published by the Board pursuant to section 6, an employer shall not be prohibited from permitting employees to confer with him during working hours without loss of time or pay;

     (3) by discrimination in regard to hire or tenure of employment or any term or condition of employment to encourage or discourage membership in any labor organization: Provided, That nothing in this Act, or in any other statute of the United States, shall preclude an employer from making an agreement with a labor organization (not established, maintained, or assisted by any action defined in section 8 (a) of this Act as an unfair labor practice) to require as a condition of employment membership therein on or after the thirtieth day following the beginning of such employment or the effective date of such agreement, whichever is the later, (i) if such labor organization is the representative of the employees as provided in section 9 (a), in the appropriate collective-bargaining unit covered by such agreement when made; and (ii) if, following the most recent election held as provided in section 9(e) the Board shall have certified that at least a majority of the employees eligible to vote in such election have voted to authorize such labor organization to make such an agreement: Provided further, That no employer shall justify any discrimination against an employee for nonmembership in a labor organization (A) if he has reasonable grounds for believing that such membership was not available to the employee on the same terms and conditions generally applicable to other members, or (B) if he has reasonable grounds for believing that membership was denied or terminated for reasons other than the failure of the employee to tender the periodic dues and the initiation fees uniformly required as a condition of acquiring or retaining membership;

     (4) to discharge or otherwise discriminate against an employee because he has filed charges or given testimony under this Act;

     (5) to refuse to bargain collectively with the representatives of his employees, subject to the provisions of section 9(a).

(b) It shall be an unfair labor practice for a labor organization or its agents—

     (1) to restrain or coerce (A) employees in the exercise of the rights guaranteed in section 7: Provided, That this paragraph shall not impair the right of a labor organization to prescribe its own rules with respect to the acquisition or retention of membership therein; or (B) an employer in the selection of his representatives for the purposes of collective bargaining or the adjustment of grievances;

     (2) to cause or attempt to cause an employer to discriminate against an employee in violation of subsection (a) (3) or to discriminate against an employee with respect to whom membership in such organization has been denied or terminated on some ground other than his failure to tender the periodic dues and the initiation fees uniformly required as a condition of acquiring or retaining membership;

     (3) to refuse to bargain collectively with an employer, provided it is the representative of his employees subject to the provisions of section 9 (a);

     (4) to engage in, or to induce or encourage the employees of any employer to engage in, a strike or a concerted refusal in the course of their employment to use, manufacture, process, transport, or otherwise handle or work on any goods, articles, materials, or commodities or to perform any services, where an object thereof is: (A) forcing or requiring any employer or self-employed person to join any labor or employer organization or any employer or other person to cease using, selling, handling, transporting, or otherwise dealing in the products of any other producer, processor, or manufacturer, or to cease doing business with any other person; (B) forcing or requiring any other employer to recognize or bargain with a labor organization as the representative of his employees unless such labor organization has been certified as the representative of such employees under the provisions of section 9; (C) forcing or requiring any employer to recognize or bargain with a particular labor organization as the representative of his employees if another labor organization has been certified as the representative of such employees under the provisions of section 9; (D) forcing or requiring any employer to assign particular work to employees in a particular labor organization or in a particular trade, craft, or class rather than to employees in another labor organization or in another trade, craft, or class, unless such employer is failing to conform to an order or certification of the Board determining the bargaining representative for employees performing such work: Provided, That nothing contained in this subsection (b) shall be construed to make unlawful a refusal by any person to enter upon the premises of any employer (other than his own employer), if the employees of such employer are engaged in a strike ratified or approved by a representative of such employees whom such employer is required to recognize under this Act;

     (5) to require of employees covered by an agreement authorized under subsection (a) (3) the payment, as a condition precedent to becoming a member of such organization, of a fee in an amount which the Board finds excessive or discriminatory under all the circumstances. In making such a finding, the Board shall consider, among other relevant factors, the practices and customs of labor organizations in the particular industry, and the wages currently paid to the employees affected; and

     (6) to cause or attempt to cause an employer to pay or deliver or agree to pay or deliver any money or other thing of value, in the nature of an exaction, for services which are not performed or not to be performed.

(c) The expressing of any views, argument, or opinion, or the dissemination thereof, whether in written, printed, graphic, or visual form, shall not constitute or be evidence of an unfair labor practice under any of the provisions of this Act, if such expression contains no threat of reprisal or force or promise of benefit.

(d) For the purposes of this section, to bargain collectively is the performance of the mutual obligation of the employer and the representative of the employees to meet at reasonable times and confer in good faith with respect to wages, hours, and other terms and conditions of employment, or the negotiation of an agreement, or any question arising thereunder, and the execution of a written contract incorporating any agreement reached if requested by either party, but such obligation does not compel either party to agree to a proposal or require the making of a concession: Provided, That where there is in effect a collective-bargaining contract covering employees in an industry affecting commerce, the duty to bargain collectively shall also mean that no party to such contract shall terminate or modify such contract, unless the party desiring such termination or modification—

     (1) serves a written notice upon the other party to the contract of the proposed termination or modification sixty days prior to the expiration date thereof, or in the event such contract contains no expiration date, sixty days prior to the time it is proposed to make such termination or modification;

     (2) offers to meet and confer with the other party for the purpose of negotiating a new contract or a contract containing the proposed modifications;

     (3) notifies the Federal Mediation and Conciliation Service witbin thirty days after such notice of the existence of a dispute, and simultaneously therewith notifies any State or Territorial agency established to mediate and conciliate disputes within the State or Territory where the dispute occurred, provided no agreement has been reached by that time; and

     (4) continues in full force and effect, without resorting to strike or lock-out, all the terms and conditions of the existing contract for a period of sixty days after such notice is given or until the expiration date of such contract, whichever occurs later:

The duties imposed upon employers, employees, and labor organizations by paragraphs (2), (3), and (4) shall become inapplicable upon an intervening certification of the Board, under which the labor organization or individual, which is a party to the contract, has been superseded as or ceased to be the representative of the employees subject to the provisions of section 9 (a), and the duties so imposed shall not be construed as requiring either party to discuss or agree to any modification of the terms and conditions contained in a contract for a fixed period, if such modification is to become effective before such terms and conditions can be reopened under the provisions of the contract. Any employee who engages in a strike within the sixty-day period specified in this subsection shall lose his status as an employee of the employer engaged in the particular labor dispute, for the purposes of sections 8, 9, and 10 of this Act, as amended, but such loss of status for such employee shall terminate if and when he is reemployed by such employer. . . .

Prevention of Unfair Labor Practices

Sec. 10. (a) The Board is empowered, as hereinafter provided, to prevent any person from engaging in any unfair labor practice (listed in section 8) affecting commerce. This power shall not be affected by any other means of adjustment or prevention that has been or may be established by agreement, law, or otherwise: Provided, That the Board is empowered by agreement with any agency of any State or Territory to cede to such agency jurisdiction over any cases in any industry (other than mining, manufacturing, communications, and transportation except where predominantly local in character) even though such cases may involve labor disputes affecting commerce, unless the provision of the State or Territorial statute applicable to the determination of such cases by such agency is inconsistent with the corresponding provision of this Act or has received a construction inconsistent therewith.

(b) Whenever it is charged that any person has engaged in or is engaging in any such unfair labor practice, the Board, or any agent or agency designated by the Board for such purposes, shall have power to issue and cause to be served upon such person a complaint stating the charges in that respect, and containing a notice of hearing before the Board or a member thereof, or before a designated agent or agency, at a place therein fixed, not less than five days after the serving of said complaint: Provided, That no complaint shall issue based upon any unfair labor practice occurring more than six months prior to the filing of the charge with the Board and the service of a copy thereof upon the person against whom such charge is made, unless the person aggrieved thereby was prevented from filing such charge by reason of service in the armed forces, in which event the six-month period shall be computed from the day of his discharge. Any such complaint may be amended by the member, agent, or agency conducting the hearing or the Board in its discretion at any time prior to the issuance of an order based thereon. The person so complained of shall have the right to file an answer to the original or amended complaint and to appear in person or otherwise and give testimony at the place and time fixed in the complaint. In the discretion of the member, agent, or agency conducting the hearing or the Board, any other person may be allowed to intervene in the said proceeding and to present testimony. Any such proceeding shall, so far as practicable, be conducted in accordance with the rules of evidence applicable in the district courts of the United States under the rules of civil procedure for the district courts of the United States, adopted by the Supreme Court of the United States pursuant to the Act of June 19, 1934 (U. S. C., title 28, secs. 723-B, 723-C).

(c) The testimony taken by such member, agent, or agency or the Board shall be reduced to writing and filed with the Board. Thereafter, in its discretion, the Board upon notice may take further testimony or hear argument. If upon the preponderance of the testimony taken the Board shall be of the opinion that any person named in the complaint has engaged in or is engaging in any such unfair labor practice, then the Board shall state its findings of fact and shall issue and cause to be served on such person an order requiring such person to cease and desist from such unfair labor practice, and to take such affirmative action including reinstatement of employees with or without back pay, as will effectuate the policies of this Act: Provided, That where an order directs reinstatement of an employee, back pay may be required of the employer or labor organization, as the case may be, responsible for the discrimination suffered by him: And provided further, That in determining whether a complaint shall issue alleging a violation of section 8 (a) (1) or section 8 (a) (2), and in deciding such cases, the same regulations and rules of decision shall apply irrespective of whether or not the labor organization affected is affiliated with a labor organization national or international in scope. Such order may further require such person to make reports from time to time showing the extent to which it has complied with the order. If upon the preponderance of the testimony taken the Board shall not be of the opinion that the person named in the complaint has engaged in or is engaging in any such unfair labor practice, then the Board shall state its findings of fact and shall issue an order dismissing the said complaint. No order of the Board shall require the reinstatement of any individual as an employee who has been suspended or discharged, or the payment to him of any back pay, if such individual was. suspended or discharged for cause. In case the evidence is presented before a member of the Board, or before an examiner or examiners thereof, such member, or such examiner or examiners, as the case may be, shall issue and cause to be served on the parties to the proceeding a proposed report, together with a recommended order, which shall be filed with the Board, and if no exceptions are filed within twenty days after service thereof upon such parties, or within such further period as the Board may authorize, such recommended order shall become the order of the Board and become effective as therein prescribed.

(d) Until a transcript of the record in a case shall have been filed in a court, as hereinafter provided, the Board may at any time, upon reasonable notice and in such manner as it shall deem proper, modify or set aside, in whole or in part, any finding or order made or issued by it.

(e) The Board shall have power to petition any circuit court of appeals of the United States (including the United States Court of Appeals for the District of Columbia), or if all the circuit courts of appeals to which application may be made are in vacation, any district court of the United States (including the District Court of the United States for the District of Columbia), within any circuit or district, respectively, wherein the unfair labor practice in question occurred or wherein such person resides or transacts business, for the enforcement of such order and for appropriate temporary relief or restraining order, and shall certify and file in the court a transcript of the entire record in the proceedings, including the pleadings and testimony upon which such order was entered and the findings and order of the Board. Upon such filing, the court shall cause notice thereof to be served upon such person, and thereupon shall have jurisdiction of the proceeding and of the question determined therein, and shall have power to grant such temporary relief or restraining order as it deems just and proper, and to make and enter upon the pleadings, testimony, and proceedings set forth in such transcript a decree enforcing, modifying, and enforcing as so modified, or setting aside in whole or in part the order of the Board. No objection that has not been urged before the Board, its member, agent, or agency, shall be considered by the court, unless the failure or neglect to urge such objection shall be excused because of extraordinary circumstances. The findings of the Board with respect to questions of fact if supported by substantial evidence on the record considered as a whole shall be conclusive. If either party shall apply to the court for leave to adduce additional evidence and shall show to the satisfaction of the court that such additional evidence is material and that there were reasonable grounds for the failure to adduce such evidence in the hearing before the Board, its member, agent, or agency, the court may order such additional evidence to be taken before the Board, its members, agent, or agency, and to be made a part of the transcript. The Board may modify its findings as to the facts, or make new findings, by reason of additional evidence so taken and filed, and it shall file such modified or new findings, which findings with respect to questions of fact if supported by substantial evidence on the record considered as a whole shall be conclusive, and shall file its recommendations, if any, for the modification or setting aside of its original order. The jurisdiction of the court shall be exclusive and its judgment and decree shall be final, except that the same shall be subject to review by the appropriate circuit court of appeals if application was made to the district court as hereinabove provided, and by the Supreme Court of the United States upon writ of certiorari or certification as provided in sections 239 and 240 of the Judicial Code, as amended (U. S. C., title 28, secs. 346 and 347).

(f) Any person aggrieved by a final order of the Board granting or denying in whole or in part the relief sought may obtain a review of such order in any circuit court of appeals of the United States in the circuit wherein the unfair labor practice in question was alleged to have been engaged in or wherein such person resides or transacts business, or in the United States Court of Appeals for the District of Columbia, by filing in such court a written petition praying that the order of the Board be modified or set aside. A copy of such petition shall be forthwith served upon the Board, and thereupon the aggrieved party shall file in the court a transcript of the entire record in the proceeding, certified by the Board, including the pleading and testimony upon which the order complained of was entered, and the findings and order of the Board. Upon such filing, the court shall proceed in the same manner as in the case of an application by the Board under subsection (e), and shall have the same exclusive jurisdiction to grant to the Board such temporary relief or restraining order as it deems just and proper, and in like manner to make and enter a decree enforcing, modifying, and enforcing as so modified, or setting aside in whole or in part the order of the Board; the findings of the Board with respect to questions of fact if supported by substantial evidence on the record considered as a whole shall in like manner be conclusive.

(g) The commencement of proceedings under subsection (e) or (f) of this section shall not, unless specifically ordered by the court, operate as a stay of the Board’s order.

(h) When granting appropriate temporary relief or a restraining order, or making and entering a decree enforcing, modifying, and enforcing as so modified, or setting aside in whole or in part an order on the Board, as provided in this section, the jurisdiction of courts sitting in equity shall not be limited by the Act entitled 'An Act to amend the Judicial Code and to define and limit the jurisdiction of courts sitting in equity, and for other purposes', approved March 23, 1932 (U. S. C., Supp. VII, title 29, secs. 101-115).

(i) Petitions filed under this Act shall be heard expeditiously, and if possible within ten days after they have been docketed.

(j) The Board shall have power, upon issuance of a complaint as provided in subsection (b) charging that any person has engaged in or is engaging in an unfair labor practice, to petition any district court of the United States (including the District Court of the United States for the District of Columbia), within any district wherein the unfair labor practice in question is alleged to have occurred or wherein such person resides or transacts business, for appropriate temporary relief or restraining order. Upon the filing of any such petition the court shall cause notice thereof to be served upon such person, and thereupon shall have jurisdiction to grant to the Board such temporary relief or restraining order as it deems just and proper.

(k) Whenever it is charged that any person has engaged in an unfair labor practice within the meaning of paragraph (4) (D) of section 8 (b), the Board is empowered and directed to hear and determine the dispute out of which such unfair labor practice shall have arisen, unless, within ten days after notice that such charge has been filed, the parties to such dispute submit to the Board satisfactory evidence that they have adjusted, or agreed upon methods for the voluntary adjustment of, the dispute. Upon compliance by the parties to the dispute with the decision of the Board or upon such voluntary adjustment of the dispute, such charge shall be dismissed.

(l) Whenever it is charged that any person has engaged in an unfair labor practice within the meaning of paragraph (4) (A), (B), or (C) of section 8 (b), the preliminary investigation of such charge shall be made forthwith and given priority over all other cases except cases of like character in the office where it is filed or to which it is referred. If, after such investigation, the officer or regional attorney to whom the matter may be referred has reasonable cause to believe such charge is true and that a complaint should issue, he shall, on behalf of the Board, petition any district court of the United States (including the District Court of the United States for the District of Columbia) within any district where the unfair labor practice in question has occurred, is alleged to have occurred, or wherein such person resides or transacts business, for appropriate injunctive relief pending the final adjudication of the Board with respect to such matter. Upon the filing of any such petition the district court shall have jurisdiction to grant such injunctive relief or temporary restraining order as it deems just and proper, notwithstanding any other provision of law: Provided further, That no temporary restraining order shall be issued without notice unless a petition alleges that substantial and irreparable injury to the charging party will be unavoidable and such temporary restraining order shall be effective for no longer than five days and will become void at the expiration of such period. Upon filing of any such petition the courts shall cause notice thereof to be served upon any person involved in the charge and such person, including the charging party, shall be given an opportunity to appear by counsel and present any relevant testimony: Provided further, That for the purposes of this subsection district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers or agents are engaged in promoting or protecting the interests of employee members. The service of legal process upon such officer or agent shall constitute service upon the labor organization and make such organization a party to the suit. In situations where such relief is appropriate the procedure specified herein shall apply to charges with respect to section 8 (b) (4) (D). . . .

Limitations

Sec. 13. Nothing in this Act, except as specifically provided for herein, shall be construed so as either to interfere with or impede or diminish in any way the right to strike, or to affect the limitations or qualifications on that right.

Sec. 14. (a) Nothing herein shall prohibit any individual employed as a supervisor from becoming or remaining a member of a labor organization, but no employer subject to this Act shall be compelled to deem individuals defined herein as supervisors as employees for the purpose of any law, either national or local, relating to collective bargaining. “(b) Nothing in this Act shall be construed as authorizing the execution or application of agreements requiring membership in a labor organization as a condition of employment in any State or Territory in which such execution or application is prohibited by State or Territorial law. . . .
