The mediation services of the Board may be invoked by the parties, or either party, to a dispute between an employee or group of employees and a carrier concerning changes in rates of pay, rules, or working conditions not adjusted by the parties in conference; also, concerning a dispute not referable to the National Railroad Adjustment Board or appropriate airline adjustment board, when not adjusted in conference between the parties, or where conferences are refused. The National Mediation Board may proffer its services in case any labor emergency is found by it to exist at any time.

Under section 5, Second, of title I of the Railway Labor Act, in any case in which a controversy arises over the meaning or application of any agreement reached through mediation, either party to said agreement, or both, may apply to the National Mediation Board for an interpretation of the meaning or application of such agreement. Upon receipt of such request, the Board shall, after a hearing of both sides, give its interpretation within 30 days.

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 the Railway Labor Act, it is the duty of the Board, upon request of either party to the dispute, to investigate such dispute and certify to both parties, in writing, the name or names of individuals or organizations that have been designated and authorized to represent the employees involved in the dispute, and to certify the same to the carrier.

In conducting such investigation, the Board is 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. Except in unusual or extraordinary circumstances, in a secret ballot the Board shall determine the choice of representative based on the majority of valid ballots cast.

In the conduct of a representation election, the Board shall designate who may participate in the election, which may include a public hearing on craft or class, and establish the rules to govern the election, or may appoint a committee of three neutral persons who after hearing shall within 10 days designate the employees who may participate in the election.

Under the Railway Labor Act the Board has access to and has power to make copies of the books and records of the carriers to obtain and utilize such information as may be necessary to fulfill its duties with respect to representatives of carrier employees.

As mentioned in § 1202.3, when disputes arise between parties to a representation dispute, the National Mediation Board is authorized by the Act to determine who may participate in the selection of employees representatives.

In the event the contesting parties or organizations are unable to agree on the employees eligible to participate in the selection of representatives, and either party makes application by letter for a formal hearing before the Board to determine the dispute, the Board may in its discretion hold a public hearing, at which all parties interested may present their contentions and argument, and at which the carrier concerned is usually invited to present factual information. At the conclusion of such hearings the Board customarily invites all interested parties to submit briefs supporting their views, and after considering the evidence and briefs, the Board makes a determination or finding, specifying the craft or class of employees eligible to participate in the designation of representatives.

Section 5, Third, (a) of the Railway Labor Act provides in the event mediation of a dispute is unsuccessful, the Board endeavors to induce the parties to submit their controversy to arbitration. If the parties so agree, and the arbitrators named by the parties are unable to agree upon the neutral arbitrator or arbitrators, as provided in section 7 of the Railway Labor Act, it becomes the duty of the Board to name such neutral arbitrators and fix the compensation for such service. In performing this duty, the Board is required to appoint only those whom it deems wholly disinterested in the controversy, and to be impartial and without bias as between the parties thereto.

Section 3, Third, (e) title I of the act makes it the duty of the National Mediation Board to appoint and fix the compensation for service a neutral person known as a “referee” in any case where a division of the National Railroad Adjustment Board becomes deadlocked on an award, such referee to sit with the division and make an award. The National Mediation Board in appointing referees is bound by the same requirements that apply in the appointment of neutral arbitrators as outlined in § 1202.9

Under the terms of section 10 of the Railway Labor Act, if a dispute between a carrier and its employees is not adjusted through mediation or the other procedures prescribed by the act, and should, in the judgment of the National Mediation Board, threaten to interrupt interstate commerce to a degree such as to deprive any section of the country of essential transportation service, the Board shall notify the President, who may thereupon, in his discretion, create an emergency board to investigate and report to him respecting such dispute. An emergency board may be composed of such number of persons as the President designates, and persons so designated shall not be pecuniarily or otherwise interested in any organization of employees or any carrier. The compensation of emergency board members is fixed by the President. An emergency board is created separately in each instance, and is required to investigate the facts as to the dispute and report thereon to the President within 30 days from the date of its creation.

Under section 205, title II, of the Railway Labor Act, when in the judgment of the National Mediation Board it becomes necessary to establish a permanent national board of adjustment for the air carriers subject to the act to provide for the prompt and orderly settlement of disputes between the employees and the carriers growing out of grievances, or out of the application or interpretation of working agreements, the Board is empowered by its order made, published, and served, to direct the air carriers and labor organizations, national in scope, to select and designate four representatives to constitute a Board known as the National Air Transport Adjustment Board. Two members each shall be selected by the air carriers and the labor organizations of their employees. Up to the present time, it has not been considered necessary to establish the National Air Transport Adjustment Board.

By the terms of title II of the Railway Labor Act, which was approved April 10, 1936, all of title I, except section 3, which relates to the National Railroad Adjustment Board, was extended to cover every common carrier by air engaged in interstate or foreign commerce, and every carrier by air transporting mail for or under contract with the United States Government, and to all employees or subordinate officials of such air carriers.

Section 3, First, (f) of title I of the Railway Labor Act relating to the settlement of disputes among labor organizations as to the qualification of any such organization to participate in the selection of labor members of the Adjustment Board, places certain duties upon the National Mediation Board. This section of the act is quoted below:

(a) In the event briefs are authorized by the Board or the assigned Hearing Officer, principal briefs shall not exceed fifty (50) pages in length and reply briefs, if permitted, shall not exceed twenty-five (25) pages in length unless the participant desiring to submit a brief in excess of such limitation requests a waiver of such limitation from the Board which is received within five (5) days of the date on which the briefs were ordered or, in the case of a reply brief, within five (5) days of receipt of the principal brief, and in such cases the Board may require the filing of a summary of argument, suitably paragraphed which shoud be a succinct, but accurate and clear, condensation of the argument actually made in the brief.

(b) The page limitations provided by this section (§ 1202.15) are exclusive of those pages containing the table of contents, tables of citations and any copies of administrative or court decisions which have been cited in the brief. All briefs shall be submitted on standard 8 1/2 × 11 inch paper with double spaced type.

(c) Briefs not complying with this section (§ 1202.15) will be returned promptly to their initiators.
