45 U.S.C. § 152 — General duties

First. Duty of carriers and employees to settle disputes

It shall be the duty of all carriers, their officers, agents, and employees to exert every reasonable effort to make and maintain agreements concerning rates of pay, rules, and working conditions, and to settle all disputes, whether arising out of the application of such agreements or otherwise, in order to avoid any interruption to commerce^* or to the operation of any carrier^* growing out of any dispute between the carrier and the employees thereof.

Second. Consideration of disputes by representatives

All disputes between a carrier or carriers and its or their employees shall be considered, and, if possible, decided, with all expedition, in conference between representatives designated and authorized so to confer, respectively, by the carrier or carriers and by the employees thereof interested in the dispute.

Third. Designation of representatives

Representatives, for the purposes of this chapter, shall be designated by the respective parties without interference, influence, or coercion by either party over the designation of representatives by the other; and neither party shall in any way interfere with, influence, or coerce the other in its choice of representatives. Representatives of employees for the purposes of this chapter need not be persons in the employ of the carrier, and no carrier shall, by interference, influence, or coercion seek in any manner to prevent the designation by its employees as their representatives of those who or which are not employees of the carrier.

Fourth. Organization and collective bargaining; freedom from interference by carrier; assistance in organizing or maintaining organization by carrier forbidden; deduction of dues from wages forbidden

Employees shall have the right to organize and bargain collectively through representatives of their own choosing. The majority of any craft or class of employees shall have the right to determine who shall be the representative^* of the craft or class for the purposes of this chapter. No carrier, its officers, or agents shall deny or in any way question the right of its employees to join, organize, or assist in organizing the labor organization of their choice, and it shall be unlawful for any carrier to interfere in any way with the organization of its employees, or to use the funds of the carrier in maintaining or assisting or contributing to any labor organization, labor representative, or other agency of collective bargaining, or in performing any work therefor, or to influence or coerce employees in an effort to induce them to join or remain or not to join or remain members of any labor organization, or to deduct from the wages of employees any dues, fees, assessments, or other contributions payable to labor organizations, or to collect or to assist in the collection of any such dues, fees, assessments, or other contributions: Provided, That nothing in this chapter shall be construed to prohibit a carrier from permitting an employee, individually, or local representatives of employees from conferring with management during working hours without loss of time, or to prohibit a carrier from furnishing free transportation to its employees while engaged in the business of a labor organization.

Fifth. Agreements to join or not to join labor organizations forbidden

No carrier, its officers, or agents shall require any person seeking employment to sign any contract or agreement promising to join or not to join a labor organization; and if any such contract has been enforced prior to the effective date of this chapter, then such carrier shall notify the employees by an appropriate order that such contract has been discarded and is no longer binding on them in any way.

Sixth. Conference of representatives; time; place; private agreements

In case of a dispute between a carrier or carriers and its or their employees, arising out of grievances or out of the interpretation or application of agreements concerning rates of pay, rules, or working conditions, it shall be the duty of the designated representative or representatives of such carrier or carriers and of such employees, within ten days after the receipt of notice of a desire on the part of either party to confer in respect to such dispute, to specify a time and place at which such conference shall be held: Provided, (1) That the place so specified shall be situated upon the line of the carrier involved or as otherwise mutually agreed upon; and (2) that the time so specified shall allow the designated conferees reasonable opportunity to reach such place of conference, but shall not exceed twenty days from the receipt of such notice: And provided further, That nothing in this chapter shall be construed to supersede the provisions of any agreement (as to conferences) then in effect between the parties.

Seventh. Change in pay, rules, or working conditions contrary to agreement or to section 156 forbidden

No carrier, its officers, or agents shall change the rates of pay, rules, or working conditions of its employees, as a class, as embodied in agreements except in the manner prescribed in such agreements or in section 156 of this title.

Eighth. Notices of manner of settlement of disputes; posting

Every carrier shall notify its employees by printed notices in such form and posted at such times and places as shall be specified by the Mediation Board^* that all disputes between the carrier and its employees will be handled in accordance with the requirements of this chapter, and in such notices there shall be printed verbatim, in large type, the third, fourth, and fifth paragraphs of this section. The provisions of said paragraphs are made a part of the contract of employment between the carrier and each employee, and shall be held binding upon the parties, regardless of any other express or implied agreements between them.

Ninth. Disputes as to identity of representatives; designation by Mediation Board; secret elections

If any dispute shall arise among a carrier’s employees as to who are the representatives of such employees designated and authorized in accordance with the requirements of this chapter, it shall be the duty of the Mediation Board, upon request of either party to the dispute, to investigate such dispute and to certify to both parties, in writing, within thirty days after the receipt of the invocation of its services, the name or names of the individuals or organizations that have been designated and authorized to represent the employees involved in the dispute, and certify the same to the carrier. Upon receipt of such certification the carrier shall treat with the representative so certified as the representative of the craft or class for the purposes of this chapter. In such an investigation, the Mediation Board shall be authorized to take a secret ballot of the employees involved, or to utilize any other appropriate method of ascertaining the names of their duly designated and authorized representatives in such manner as shall insure the choice of representatives by the employees without interference, influence, or coercion exercised by the carrier. In the conduct of any election for the purposes herein indicated the Board shall designate who may participate in the election and establish the rules to govern the election, or may appoint a committee of three neutral persons who after hearing shall within ten days designate the employees who may participate in the election. In any such election for which there are 3 or more options (including the option of not being represented by any labor organization) on the ballot and no such option receives a majority of the valid votes cast, the Mediation Board shall arrange for a second election between the options receiving the largest and the second largest number of votes. The Board shall have access to and have power to make copies of the books and records of the carriers to obtain and utilize such information as may be deemed necessary by it to carry out the purposes and provisions of this paragraph.

Tenth. Violations; prosecution and penalties

The willful failure or refusal of any carrier, its officers or agents, to comply with the terms of the third, fourth, fifth, seventh, or eighth paragraph of this section shall be a misdemeanor, and upon conviction thereof the carrier, officer, or agent offending shall be subject to a fine of not less than $1,000, nor more than $20,000, or imprisonment for not more than six months, or both fine and imprisonment, for each offense, and each day during which such carrier, officer, or agent shall willfully fail or refuse to comply with the terms of the said paragraphs of this section shall constitute a separate offense. It shall be the duty of any United States attorney to whom any duly designated representative of a carrier’s employees may apply to institute in the proper court and to prosecute under the direction of the Attorney General of the United States, all necessary proceedings for the enforcement of the provisions of this section, and for the punishment of all violations thereof and the costs and expenses of such prosecution shall be paid out of the appropriation for the expenses of the courts of the United States: Provided, That nothing in this chapter shall be construed to require an individual employee to render labor or service without his consent, nor shall anything in this chapter be construed to make the quitting of his labor by an individual employee an illegal act; nor shall any court issue any process to compel the performance by an individual employee of such labor or service, without his consent.

Eleventh. Union security agreements; check-off

Notwithstanding any other provisions of this chapter, or of any other statute or law of the United States, or Territory thereof, or of any State, any carrier or carriers as defined in this chapter and a labor organization or labor organizations duly designated and authorized to represent employees in accordance with the requirements of this chapter shall be permitted—

(a) to make agreements, requiring, as a condition of continued employment, that within sixty days following the beginning of such employment, or the effective date of such agreements, whichever is the later, all employees shall become members of the labor organization representing their craft or class: Provided, That no such agreement shall require such condition of employment with respect to employees to whom membership is not available upon the same terms and conditions as are generally applicable to any other member or with respect to employees to whom membership was denied or terminated for any reason other than the failure of the employee to tender the periodic dues, initiation fees, and assessments (not including fines and penalties) uniformly required as a condition of acquiring or retaining membership.

(b) to make agreements providing for the deduction by such carrier or carriers from the wages of its or their employees in a craft or class and payment to the labor organization representing the craft or class of such employees, of any periodic dues, initiation fees, and assessments (not including fines and penalties) uniformly required as a condition of acquiring or retaining membership: Provided, That no such agreement shall be effective with respect to any individual employee until he shall have furnished the employer with a written assignment to the labor organization of such membership dues, initiation fees, and assessments, which shall be revocable in writing after the expiration of one year or upon the termination date of the applicable collective agreement, whichever occurs sooner.

(c) The requirement of membership in a labor organization in an agreement made pursuant to subparagraph (a) of this paragraph shall be satisfied, as to both a present or future employee in engine, train, yard, or hostling service, that is, an employee engaged in any of the services or capacities covered in the First division of paragraph (h) of section 153 of this title defining the jurisdictional scope of the First Division of the National Railroad Adjustment Board^*, if said employee shall hold or acquire membership in any one of the labor organizations, national in scope, organized in accordance with this chapter and admitting to membership employees of a craft or class in any of said services; and no agreement made pursuant to subparagraph (b) of this paragraph shall provide for deductions from his wages for periodic dues, initiation fees, or assessments payable to any labor organization other than that in which he holds membership: Provided, however, That as to an employee in any of said services on a particular carrier at the effective date of any such agreement on a carrier, who is not a member of any one of the labor organizations, national in scope, organized in accordance with this chapter and admitting to membership employees of a craft or class in any of said services, such employee, as a condition of continuing his employment, may be required to become a member of the organization representing the craft in which he is employed on the effective date of the first agreement applicable to him: Provided, further, That nothing herein or in any such agreement or agreements shall prevent an employee from changing membership from one organization to another organization admitting to membership employees of a craft or class in any of said services.

(d) Any provisions in paragraphs Fourth and Fifth of this section in conflict herewith are to the extent of such conflict amended.

Twelfth. Showing of interest for representation elections

The Mediation Board, upon receipt of an application requesting that an organization or individual be certified as the representative of any craft or class of employees, shall not direct an election or use any other method to determine who shall be the representative of such craft or class unless the Mediation Board determines that the application is supported by a showing of interest from not less than 50 percent of the employees in the craft or class.
