§ 151. Findings and declaration of policy

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 collective 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.

§ 158. Unfair labor practices
(a) Unfair labor practices by employerIt 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 157 of this title;
(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 156 of this title, 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 subchapter, 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 this subsection 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 159(a) of this title, in the appropriate collective-bargaining unit covered by such agreement when made, and (ii) unless following an election held as provided in section 159(e) of this title within one year preceding the effective date of such agreement, the Board shall have certified that at least a majority of the employees eligible to vote in such election have voted to rescind the authority of 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 subchapter;
(5) to refuse to bargain collectively with the representatives of his employees, subject to the provisions of section 159(a) of this title.
(b) Unfair labor practices by labor organizationIt 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 157 of this title: 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 159(a) of this title;
(4)
(i) to engage in, or to induce or encourage any individual employed by any person engaged in commerce or in an industry affecting commerce to engage in, a strike or a refusal in the course of his employment to use, manufacture, process, transport, or otherwise handle or work on any goods, articles, materials, or commodities or to perform any services; or (ii) to threaten, coerce, or restrain any person engaged in commerce or in an industry affecting commerce, where in either case an object thereof is—
(A) forcing or requiring any employer or self-employed person to join any labor or employer organization or to enter into any agreement which is prohibited by subsection (e);
(B) forcing or requiring any 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, or 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 159 of this title: Provided, That nothing contained in this clause (B) shall be construed to make unlawful, where not otherwise unlawful, any primary strike or primary picketing;
(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 159 of this title;
(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:
(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;
(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; and
(7) to picket or cause to be picketed, or threaten to picket or cause to be picketed, any employer where an object thereof is forcing or requiring an employer to recognize or bargain with a labor organization as the representative of his employees, or forcing or requiring the employees of an employer to accept or select such labor organization as their collective bargaining representative, unless such labor organization is currently certified as the representative of such employees:
(A) where the employer has lawfully recognized in accordance with this subchapter any other labor organization and a question concerning representation may not appropriately be raised under section 159(c) of this title,
(B) where within the preceding twelve months a valid election under section 159(c) of this title has been conducted, or
(C) where such picketing has been conducted without a petition under section 159(c) of this title being filed within a reasonable period of time not to exceed thirty days from the commencement of such picketing: Provided, That when such a petition has been filed the Board shall forthwith, without regard to the provisions of section 159(c)(1) of this title or the absence of a showing of a substantial interest on the part of the labor organization, direct an election in such unit as the Board finds to be appropriate and shall certify the results thereof: Provided further, That nothing in this subparagraph (C) shall be construed to prohibit any picketing or other publicity for the purpose of truthfully advising the public (including consumers) that an employer does not employ members of, or have a contract with, a labor organization, unless an effect of such picketing is to induce any individual employed by any other person in the course of his employment, not to pick up, deliver or transport any goods or not to perform any services.
Nothing in this paragraph (7) shall be construed to permit any act which would otherwise be an unfair labor practice under this subsection.
(c) Expression of views without threat of reprisal or force or promise of benefit
(d) Obligation to bargain collectivelyFor 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 within 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) to (4) of this subsection 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 159(a) of this title, 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 any notice period specified in this subsection, or who engages in any strike within the appropriate period specified in subsection (g) of this section, shall lose his status as an employee of the employer engaged in the particular labor dispute, for the purposes of sections 158, 159, and 160 of this title, but such loss of status for such employee shall terminate if and when he is reemployed by such employer. Whenever the collective bargaining involves employees of a health care institution, the provisions of this subsection shall be modified as follows:
(A) The notice of paragraph (1) of this subsection shall be ninety days; the notice of paragraph (3) of this subsection shall be sixty days; and the contract period of paragraph (4) of this subsection shall be ninety days.
(B) Where the bargaining is for an initial agreement following certification or recognition, at least thirty days’ notice of the existence of a dispute shall be given by the labor organization to the agencies set forth in paragraph (3) of this subsection.
(C) After notice is given to the Federal Mediation and Conciliation Service under either clause (A) or (B) of this sentence, the Service shall promptly communicate with the parties and use its best efforts, by mediation and conciliation, to bring them to agreement. The parties shall participate fully and promptly in such meetings as may be undertaken by the Service for the purpose of aiding in a settlement of the dispute.
(e) Enforceability of contract or agreement to boycott any other employer; exception
(f) Agreement covering employees in the building and construction industry
(g) Notification of intention to strike or picket at any health care institution

§ 158a. Providing facilities for operations of Federal Credit Unions

(A) by an employee or group of employees or any individual or labor organization acting in their behalf alleging that a substantial number of employees (i) wish to be represented for collective bargaining and that their employer declines to recognize their representative as the representative defined in subsection (a), or (ii) assert that the individual or labor organization, which has been certified or is being currently recognized by their employer as the bargaining representative, is no longer a representative as defined in subsection (a); or
(B) by an employer, alleging that one or more individuals or labor organizations have presented to him a claim to be recognized as the representative defined in subsection (a);
the Board shall investigate such petition and if it has reasonable cause to believe that a question of representation affecting commerce exists shall provide for an appropriate hearing upon due notice. Such hearing may be conducted by an officer or employee of the regional office, who shall not make any recommendations with respect thereto. If the Board finds upon the record of such hearing that such a question of representation exists, it shall direct an election by secret ballot and shall certify the results thereof.
(2) In determining whether or not a question of representation affecting commerce exists, the same regulations and rules of decision shall apply irrespective of the identity of the persons filing the petition or the kind of relief sought and in no case shall the Board deny a labor organization a place on the ballot by reason of an order with respect to such labor organization or its predecessor not issued in conformity with section 160(c) of this title.
(3) No election shall be directed in any bargaining unit or any subdivision within which in the preceding twelve-month period, a valid election shall have been held. Employees engaged in an economic strike who are not entitled to reinstatement shall be eligible to vote under such regulations as the Board shall find are consistent with the purposes and provisions of this subchapter in any election conducted within twelve months after the commencement of the strike. In any election where none of the choices on the ballot receives a majority, a run-off shall be conducted, the ballot providing for a selection between the two choices receiving the largest and second largest number of valid votes cast in the election.
(4) Nothing in this section shall be construed to prohibit the waiving of hearings by stipulation for the purpose of a consent election in conformity with regulations and rules of decision of the Board.
(5) In determining whether a unit is appropriate for the purposes specified in subsection (b) the extent to which the employees have organized shall not be controlling.
(d) Petition for enforcement or review; transcript

(2) No election shall be conducted pursuant to this subsection in any bargaining unit or any subdivision within which, in the preceding twelve-month period, a valid election shall have been held.
