The sole question presented by this appeal is whether the Industrial Commission of Arizona is a state agency established to mediate and conciliate disputes.

If it is such an agency, then the Brotherhood of Locomotive Firemen & Engine-men (Firemen) and the Brotherhood of Railroad Trainmen (Trainmen) were guilty of an unfair labor practice because of their failure to notify the Arizona Commission of the existence of a dispute as required by § 8(d) (3) of the Labor Management Relations Act.

The pertinent section of the Arizona statute, as it relates to the Arizona Industrial Commission, reads:

The National Labor Relations Board (Board) contends that the language of the Arizona statute shews that the Arizona Industrial Commission has elearcut powers of mediation and conciliation and that the statements in the United States Department of Labor bulletin “A Guide to State Mediation Laws and Agencies” support such construction.

The Brotherhoods on the other hand deny that the Arizona Commission has such powers and they contend that the statute creating the Commission falls far short of informing people subject to its reach that the Commission is an agency of mediation and conciliation, particularly when construed in relation to the functions which the Commission actually performed.

Under § 8(d) of the Act, where there is a collective bargaining contract between an employer and its employees, no party may modify or terminate the contract unless such party:

The parties agree that in those cases in which the parties fail to reach an agreement among themselves, the Federal Mediation and Conciliation Service, together with state agencies established to mediate and conciliate disputes where they exist, must be given an opportunity to aid in resolving such disputes. Local Union 219, Retail Clerks International Association v. National Labor Relations Board, 1959, 105 U.S.App.D.C. 232 , 265 F.2d 814 . It is conceded that the failure to comply with those provisions constitutes a violation of the Act, and that an employee who engages in a strike in which his bargaining representative has failed to comply with the provisions of the Act, loses his status as an employee of his employer.

In this case, the Trainmen since 1942 have been the exclusive bargaining representative for the employees of Phelps-Dodge Corporation (Phelps-Dodge) at two of its Arizona plants, and the Firemen since 1954 have been the exclusive bargaining representative at the third Arizona plant of Phelps-Dodge.

In the latter part of 1959, during the period in which the Brotherhoods were meeting with Phelps-Dodge, the Brotherhoods served a 60-day notice on Phelps-Dodge of their intention to modify their collective bargaining contract, and they likewise served the 30-day notice on the Federal Mediation and Conciliation Service. No similar 30-day notice was served upon any Arizona state agency. On February 12, 1960, after the expiration of the 60-day cooling off period and after the expiration of the 30-day notice to the Federal agency, the Brotherhoods jointly called strikes and picketed all three of Phelps-Dodge’s Arizona plants.

Phelps-Dodge filed unfair labor charges against the Brotherhoods, charging among other things that the Brotherhoods, by failing to notify the Department of Labor under the Arizona Industrial Commission of the existing dispute, violated § 8(d) (3) of the Act.

At a Board hearing, Mr. Thomas Houlihan, the Director of the Arizona State Labor Department, testified that his department assists in the collection of wages due employees; patrols and enforces laws relating to children, females, and public employees; and supervises and licenses employment agencies. The three industrial commissioners devote their time and energies to the Workmen’s Compensation program. During his five years with the Commission, Mr. Houlihan has done no mediation or conciliation work, and he has never been requested to do such work. Although he had never received a notice from an employer concerning a labor dispute, he had received a few such notices from labor organizations. These notices were acknowledged and filed, and nothing further was done with respect to them. The statute did not define the duties of the Commission and the Commission did not promulgate any rules with respect to mediation or conciliation services. No funds have ever been appropriated by the Arizona legislature for mediation and conciliation services. Mr. Houlihan knew of no agency in Arizona established to mediate and conciliate labor disputes.

The Trial Examiner and the Board found that the Brotherhoods were required to give the State Labor Department an 8(d) (3) notice, and having failed to serve such a notice, the Brotherhoods were engaged in an unlawful strike, and all of the employees who engaged in this strike forfeited their rights under the Act.

We do not believe that the Arizona statute [A.R.S. § 23-107(A) (3)], particularly as construed and applied by the Arizona State Labor Department, brings that department or the Industrial Commission within the reach of the Federal Act.

The authorization of Section 23-107 (A) (3) to “promote the voluntary arbitration, mediation and conciliation of disputes” does not clearly confer upon the Industrial Commission the duty to mediate and conciliate labor disputes. It differs greatly from the mandatory language of Section 32-308, which requires that the Arizona Board of Barber Examiners “shall act as mediator and arbitrator in any controversy * *

Unlike the mediation and conciliation statutes of most states, Section 23-107 does not provide for the creation of a board of arbitration or the appointment of mediators or referees; does not set forth the circumstances under which the Commission shall offer its services or assume jurisdiction over a dispute; and does not prescribe rules of procedure for the investigation and handling of disputes or the promulgation of such rules by the Commission itself.

The strike was not called for more than 30 days after the Brotherhoods had given the Federal Mediation Service notice of the existence of the labor dispute and not until the efforts of the Federal agency to resolve the dispute had failed. A notice to the Arizona Commission would not have contributed to the conciliation or mediation process. The Arizona Commission had no history of performing such services, had neither the funds nor the personnel to perform them, and had no intention of doing so in this case.

The notice would not have extended the cooling off period during which the parties would have been required to continue their discussions because under the Act, notices to the Federal and State agencies were to be served at the same time and for the same 30-day period.

The only effect of the Brotherhoods’ failure to have served the notice on the State agency was to subject those members who participated in the strike to a forfeiture of their employee status with all that such loss implies.

The Labor Management Relations Act had a dual purpose—to substitute collective bargaining for economic warfare and to protect the rights of employees to engage in concerted activities for their own benefit. Mastro Plastics Corp. v. National Labor Relations Board, 350 U.S. 270, 284 , 76 S.Ct. 349 , 100 L.Ed. 309 (1955). “A construction which serves neither of these aims is to be avoided unless the words Congress has chosen clearly compel it.” National Labor Relations Board v. Lion Oil Co., 352 U.S. 282, 289 , 77 S.Ct. 330 , 1 L.Ed.2d 331 (1956).

We do not read § 8(d) (3) of the Federal Act as compelling us to hold that a state agency with no defined duties, no rules or regulations with reference to mediation or conciliation services, no personnel or funds with which to perform such services and no history of ever having performed such work or of ever having been requested to do it, was a “State * * * agency established to mediate and conciliate disputes”.

The language of the state statute and the history of the agency charged with its administration is a much more .reliable guide of services which the Department was authorized as well as equipped to perform, and which it did in fact perform, than the conclusions of the United States Department of Labor employees who prepared Bulletin 176, “A Guide to State Mediation Laws and Agencies”.

The petition to set aside that portion of the Board’s order which found the petitioners guilty of a Section 8(b) (3) violation is granted. The notice which petitioners are required to post in connection with a violation not here contested should be modified accordingly.
