In this action by certain employees of New York Central Railroad, located at Grand Central Terminal, against the Railroad and their Brotherhood collective bargaining agent and their local Lodge 1085, it was charged that a certain agreement of August 18, 1965, between the Railroad and the Brotherhood amounted to a discrimination against the employees at Grand Central Terminal. The first count of the complaint asserted that the terms of transfer of certain work from Mott Haven Yard to Grand Central Terminal granted “super-seniority” to the transferred Mott Haven Yard men to the detriment of plaintiffs, in violation of the duty of the Brotherhood fairly to bargain on behalf of all the employees it represents, and that in accomplishing this end the officers of the Brotherhood “agreed, colluded and conspired” with the Railroad. The second count alleged the same “super-seniority” as the imposition of “discipline,” in violation of the Labor-Management Reporting and Disclosure Act of 1959, 29 U.S.C. §§ 412, 529, for failure to afford plaintiffs the procedural safeguards prescribed by the terms of the statute. The action was designed to prevent the names of the men to be transferred from the Mott Haven Yard from being added to the Grand Central Terminal seniority roster except at the bottom. So, before the date of transfer, plaintiffs moved for a preliminary injunction restraining the Railroad from putting the dove-tailing seniority plan into effect, and the Railroad made a cross-motion to dismiss the complaint under F.R.Civ.P. 12(b) (6) and 12(b) (1) . The Brotherhood was not made a party to these proceedings, as neither the motion papers on the application for the temporary injunction nor those supporting the cross-motion to dismiss were served on the Brotherhood or its counsel. The result was an order: (1) denying the motion for a preliminary injunction; (2) dismissing the first count of the complaint “with prejudice” for failure to state a claim for relief; and (3) dismissing the second count for lack of subject matter jurisdiction. Judge Levet’s memorandum opinions are not reported. Plaintiffs appeal, and a certificate under F.R.Civ.P. 54(b) makes it proper for us to consider the order appealed from in its entirety.
As every phase of the controversy was thoroughly explored in the affidavits in support of and in opposition to the motion for a temporary injunction, and all the relevant documents were before the Court below, we think the motion to dismiss under Rule 12(b) (6) should have been treated as a motion for summary *139judgment.1 When the chronology is straightened out and the sequence of events is described, including the various collective bargaining agreements that preceded the one of August 18, 1965, it clearly appears that many questions of interpretation of various provisions in the series of collective bargaining agreements lie at the base of what plaintiffs allege as “discrimination” against them, that the decision of these questions was within the' exclusive competence of the appropriate Adjustment Board, and that summary judgment should have been granted dismissing the first count of the complaint for lack of jurisdiction over subject matter. The August 18, 1965 agreement, which lies at the very center of the case, was merely one of a series of agreements implementing prior collective bargaining agreements in specific instances where work was to be transferred, abandoned, contracted out or similarly adjusted. We have decided: (1) summary judgment should have been granted dismissing as against the Railroad the first count of the complaint, based upon alleged discrimination in violation of the Railway Labor Act, for lack of subject matter jurisdiction; (2) the second count was properly dismissed as against the Railroad as matter of law for lack of subject matter jurisdiction; and (3) the motion for a temporary injunction was properly denied.
I.
Prior to 1962, except where a shop or repair facility was wholly discontinued, the various successive collective bargaining agreements did not permit the Railroad to accredit transferred employees, whether following their work or not, with seniority accumulated at their last locality of employment. The requirement was that such transferees be treated as junior employees in respect of length of service at the point to which they were transferred.2
In 1962 a new agreement was negotiated by the nonoperating unions with the Railroad. It required 60 days’ notice to union officials when work was proposed to be transferred, with a provision for discussion of the matter before the change was made. If any new jobs were to be created at the location to which work was transferred, the employees at the original location had first rights to these jobs, according to seniority; and transferred employees were to be “included on the appropriate seniority roster at the new location with full seniority effective with the date of assignment.” This procedure of dove-tailing seniority was apparently adopted without protest. The 1962 contract also prescribed certain pay guarantees for transferred employees and unemployment insurance benefits for men whose low seniority prevented them from obtaining new jobs at the transferee location. This agreement, dated April 3, 1962, was to “become *140effective February 1, 1962 and will continue in effect thereafter subject to the provisions of the Railway Labor Act as amended.”
In 1964, a mediation agreement was negotiated at Washington, D. C., between the shop crafts unions, including the carmen’s union, and the major United States rail carriers, including New York Central.
Provision is made in the 1964 agreement for notice by a carrier of its intention to transfer work between locations and for discussions with the employees’ representative concerning such proposed transfer. Any employee continued in service after a particular “coordination” is assured that he will not be placed in a worse position with respect to compensation and rules governing working conditions than he occupied at the time of the “coordination,” this guarantee to continue for up to 5 years. On the other hand, an employee who is “deprived of employment” as a result of a “coordination” is provided with a “dismissal allowance” equal to 60% of his average monthly compensation Over the previous twelve months, and the duration of these monthly payments, up to a maximum of 60 months, is keyed to length of service. An employee is considered “deprived of employment” and entitled to this “coordination” allowance:
1. When the position which he holds on his home road is abolished as result of coordination and he is unable to obtain by the exercise of his seniority rights another position on his home road or a position in the coordinated operation, or
2. When the position he holds on his home road is not abolished but he loses that position as a result of the exercise of seniority rights by an employee whose position is abolished as a result of said coordination, or by other employees, brought about as a proximate consequence of the coordination, and if he is unable by the exercise of his seniority rights to secure another position on his home road or a position in the coordinated operation.
[Article I — Employee Protection, Section 6(c).]
Section 11 of Article I, which deals with transfer of work procedures, is most significant, in the context of the facts of this case:
When positions are abolished as a result of changes in the carrier’s operations * * * and all or part of the work of the abolished positions is transferred to another location or locations, the selection and assignment of forces to perform the work in question shall be provided for by agreement of the General Chairman of the craft or crafts involved and the carrier establishing provisions appropriate for application in the particular case; provided however, that under the terms of the agreement sufficient employees will be required to accept employment within their classification so as to insure a force adequate to meet the carrier’s requirements. In the event of failure to reach such agreement, the dispute may be submitted by either party for settlement as hereinafter provided.
What this means is that, in specific instances of “coordinations” under the 1964 national agreement, separate implementing agreements are to be negotiated by and between the General Chairman of the craft involved and the carrier regarding the details of each “coordination,” subject to the over-all policies described in the master agreement.
This brings us to the agreement of August 18, 1965, which appellants assert is invalid by reason of discrimination. In compliance with the provisions of the 1964 agreement, and on July 16, 1965, the Railroad gave notice to five affected unions of a plan to transfer the terminal servicing of five trains from its Mott Haven Yard in the Bronx to Grand Central Terminal. The Railroad proposed to reduce the work force at Mott Haven by 107 men, including 69 carmen, helpers and cleaners, and to establish 81 new positions at Grand Central Terminal, 52 of which were carmen, helpers and cleaners. Similar notices were posted on bul*141letin boards for the information of ail the employees. In further compliance with the national agreement, union and railroad representatives met to negotiate the terms of the proposed transfer. The result of these negotiations was the contract, dated August 18, 1965, between the Railroad and the Brotherhood of Railway Carmen and the Sheet Metal Workers International Association.
After stipulating the number of jobs to be transferred,3 the agreement prescribed the following procedure for filling them. Qualified bidders at Mott Haven were to have preference to the new positions, in order of seniority. If any positions were not bid in by the Mott Haven men, the Grand Central Terminal employees were then eligible for them. Most importantly, Section IV provided:
Employees transferring to Grand Central Terminal hereunder will be included on the appropriate seniority roster with full seniority, effective with the date of assignment. Simultaneously, such employee’s seniority, at Mott Haven will be terminated.
And most of the provisions of the 1964 national agreement were expressly made applicable to the transfer.
The dove-tailing of seniorities is what appellants characterize as “super-seniority.” This is alleged to constitute discrimination because- some of the 173 car cleaners, repairmen and helpers employed at Grand Central Terminal, the appellants, had been transferred to Grand Central Terminal from other facilities prior to 1962, in accordance with the practices outlined in Rule 29 of the pre1962 agreements.4 The claim is that the newly transferred men are receiving preferential treatment and that this may result in a loss of jobs by some of the appellants when work is cut back.5
As the August 18,1965 agreement was to take effect on September 18, 1965, this action was commenced on September 17, 1965, and Judge Herlands, having denied an ex parte application for a temporary restraining order, signed an order to show cause which brought on for hearing before Judge Levet the motion for a preliminary injunction to which reference has been made. By cross-motion for dismissal of the complaint, also above referred to, the entire controversy, except insofar as it affected the brotherhood which was not a party to these proceedings because not served with any of the motion papers, came before Judge Levet for determination.
II.
Whether the District Court had jurisdiction of the first alleged claim for relief depends upon whether disposition of that claim turns on questions of interpretation or application of the terms of the various agreements or solely upon the validity or invalidity of the agreement of August 18, 1965. See Cunningham v. Erie R. R. Co., 2 Cir., 1959, 266 F.2d 411; Westchester Lodge 2186, Bhd. of Ry. S. S. Clerks, etc. v. Railway Express Agency, Inc., 2 Cir., 1964, 329 F.2d 748; Roberts v. Lehigh & N. E. Ry., 3 Cir., 1963, 323 F.2d 219, 222-223; Colbert v. Brotherhood of R. R. Trainmen, 9 Cir., 1953, 206 F.2d 9, cert. denied, 1954, 346 U.S. 931, 74 S.Ct. 320, 98 L.Ed. 422. Compare Brotherhood of R. R. Trainmen v. Howard, 1952, 343 U.S. 768, 72 S.Ct. 1022, 96 L.Ed. 1283.
In limine it is to be noted, as it was by Judge Levet, that the complaint, in the first claim, does not allege “any act or *142failure to act on the part of the New York Central violating any right of the plaintiffs.” In the light of the evidence fully set forth in the affidavits in support of and in opposition to the motion for a temporary injunction, the allegation that the Railroad “agreed, colluded and conspired” means no more than that it signed the agreement of August 18, 1965; and the allegation that the dovetailing of seniorities was “arbitrarily, capriciously and in bad faith” designed to confer “certain special, unfair and undeserved advantages in seniority rights” upon the transferred Mott Haven Yard employees means no more than that the provisions requiring such dove-tailing are alleged not to be in accordance with the uniform practice since 1962. That one or more of the officers of the union were affected by the dove-tailing would seem to be inevitable and of no particular significance. In any event, there is no plain, unequivocal allegation that the Railroad participated in any deliberate, hostile discrimination, see Brotherhood of R. R. Trainmen v. Howard, supra, 343 U.S. 768, 72 S.Ct. 1022, and not a shred of proof to indicate that the Railroad did so. The prayer for relief is an injunction permanently enjoining the Railroad from adding any person to the seniority roster at Grand Central Terminal other than at the bottom of such roster, nominal damages of $1, and other “appropriate” relief.
Of the questions that are decisive of appellants’ claim of so-called “discrimination,” and that are for the Adjustment Board 6 and not for the courts to pass upon, the principal one is whether the dove-tailing expressly provided for in the agreement of August 18, 1965 “was required by and expressly incorporates the terms of the national 1964 Agreement,” as the Railroad insists. The same idea is conveyed in another part of the Railroad’s brief by the statement that the job security protection afforded under the prior local 1962 agreement “was expressly carried forward under the national agreement.” Of course, if this is so, there is plainly nothing in appellants’ first claim. For, if the accumulated seniority of those moved from one facility of the Railroad to another in instances where work was to be transferred, abandoned, contracted out or similarly adjusted, collectively referred to as “coordinations,” was specifically and deliberately preserved in the 1964 agreement, as it undoubtedly was in the 1962 agreement, the charge of discrimination would fall of its own weight. Neither the Adjustment Board nor the courts would be likely to regard dove-tailing as discriminatory in regard to these appellants'when the same method was absolutely required in the case of all similar coordinations throughout the entire country. In other words, while appellants consider it “fair” treatment to put the Mott Haven Yard men at the bottom of the Grand Central Terminal roster and to eliminate entirely the seniority rights that had accrued at the Mott Haven Yard, other persons, viewing the matter objectively, would very likely think otherwise, especially if the representatives of the railroads in general and the representatives of railway employees as well thought such treatment was not “fair” and by common consent had abrogated the old pre-1962 Rule 29.
However, we do not think the 1964 agreement is as clear on this point *143as the Railroad says it is. On the contrary, this would seem to be precisely the sort of question reserved for decision by the Adjustment Board, with its expertise in such matters and its familiarity with all types of collective bargaining agreements affecting the railroads and their employees.7
Despite what the Railroad says, we are unable to find any part of the 1964 agreement expressly carrying forward the dove-tailing provisions of the 1962 agreement. But, in the light of the various implementing agreements on the same subject affecting other crafts, we think it not improbable that the Adjustment Board will arrive at the same result by an interpretation of the following portion of Article I, Section 1 of the 1964 agreement:
Any job protection agreement which is now in effect on a particular railroad which is deemed by the authorized employee representatives to be more favorable than this Article with respect to a transaction such as those referred to in Section 2 hereof, may be preserved as to such transaction by the representatives so notifying the carrier within thirty days from the date of receipt of notice of such transaction, and the provisions of this Article will' not apply with respect to such transaction.
Other contentions of appellants would seem to do no more than raise questions of interpretation of a similar character. For example, much is said by appellants on the subject of the vast sums the Railroad may save as a result of the alleged discriminatory dove-tailing. It is at least arguable, however, that coordination allowances pursuant to the terms of the 1964 agreement, quoted in Part I of this opinion, would be available not only to those Mott Haven Yard men who do not secure employment at Grand Central Terminal (Article I, Section 6(c), paragraph 1) but also to Grand Central Terminal men who may ultimately be out of employment by reason of the “super-seniority” of the Mott Haven Yard transferees, as this might well be considered “a proximate consequence of the coordination” (Article I, Section 6(c); paragraph 2). But these questions we think are reserved for determination by the Adjustment Board and not by the courts. It is also claimed that more men were transferred from the Mott Haven Yard to Grand Central Terminal than were necessary to service the five trains, and that this was done for the purpose of accommodating a union official who would not have been included if less men had been transferred. Here again we have a question of the interpretation or application of a provision or provisions of the agreement.
Thus, while Judge Levet’s analysis, based on the face of claim one of the complaint alone, is sound, the views thus expressed seem to us to be considerably clarified and substantiated in the light of the proofs submitted in connection with the motion for a preliminary injunction. In the light of these proofs it is perfectly clear that the question of discrimination vel non depends upon the interpretation to be given to the 1964 agreement, as implemented by the August 18, 1965 agreement, and that this question of interpretation must be made by the Adjustment Board and not by the courts. Except for a possible, and we *144think very unlikely, misinterpretation by both the representatives of the Railroad and those of the Brotherhood, there is nothing to indicate any discrimination whatever, hostile or otherwise.8 Thus it is much more satisfactory, when the circumstances permit, as they do here, to treat the motion to dismiss under F.R.Civ.P. 12(b) (6) as a motion for summary judgment.
But Judge Levet did not treat the motion to dismiss as a motion for summary judgment. Does this prevent this Court on appeal from doing what should have been done in the Court below? We think not. Indeed, this very procedure has already been followed in this Circuit in Compania De Remorque Y Salvamento, S. A. v. Esperance, Inc., 1951, 187 F.2d 114, 117 n. 1. See also Larsen v. American Airlines, Inc., 2 Cir., 1963, 313 F.2d 599; Nozet v. District of Columbia, 1962, 112 U.S.App.D.C. 143, 300 F.2d 735; 2 Moore’s Federal Practice, page 2256 (2nd ed. 1965).
The principle is the same as the one we stated in 1961 in connection with the granting of summary judgment even though no cross-motion for summary judgment had been made or considered by the District Court. This principal is (291 F.2d at page 505) that when “the evidence of the facts bearing on the issues arising out of the complaint is all before the court in affidavit form, it is most desirable that the court cut through mere out-worn procedural niceties” and make the same decision as would have been made if the Court hearing the motion to dismiss had treated the motion as one for summary judgment as directed in F.R.Civ.P. 12(b). In other words, instead of speculating on the subject of the meaning of allegations on their face vague, ambiguous and for various reasons unsatisfactory, the District Court, having all the evidence before it on the motion for a preliminary injunction, will look at these proofs to determine whether there is any “genuine issue as to any material fact” and whether a party is “entitled to a judgment as a matter of law.” F.R.Civ.P. 56(c). If, as here, it is found that the District Court lacks jurisdiction because the power to decide this particular dispute is reserved by an Act of the Congress for disposition by the appropriate Adjustment Board, then it does appear that a party is entitled to judgment as a matter of law and that judgment is one dismissing the particular claim for lack of jurisdiction. Viewing the matter backwards, as it were, this is doing no more than the District Court or this Court is *145duty bound to do sua sponte whenever it appears that jurisdiction over subject matter is lacking.
III.
Appellants’ second claim for relief was properly dismissed for lack of subject matter jurisdiction in the District Court. The theory of this second claim is that the granting of the so-called “super-seniority” to the Mott Haven Yard men was a species of “discipline” imposed on the Grand Central Terminal employees by way of revenge or “reprisal” for acts of the Grand Central Terminal employees who are alleged to have been critical of the officers of the Brotherhood and of the local Lodge 1085 because of certain increases in dues and “financial malpractices.” As in the first elaim for relief, the Railroad is alleged to have “agreed, colluded and conspired” to effect this discipline. As there were no “written specific charges,” no “reasonable time to prepare his defense,” and no “fair hearing” prior to the negotiation of the agreement of August 18,1965, there is supposed to be a violation of the Union Bill of Rights provisions of the Labor-Management Reporting and Disclosure Act, specifically 29 U.S.C. §§ 411 (a) (5) and 529.
While jurisdiction of actions by persons whose rights under the Act have been infringed is given to the proper District Courts “for such relief (including injunctions) as may be appropriate,” as provided in 29 U.S.C. § 412, the following sentence of Section 412 would seem to make it clear that the actions referred to are against “a labor organization” and not against an employer. The word “appropriate” is to be read in this context. Section 529 also refers to “any labor organization, or any officer, agent, shop steward, or other representative of a labor organization, or any employee thereof.” Thus actions against persons in their representative capacity as officers of unions have been sustained. Johnson v. Nelson, 8 Cir., 1963, 325 F.2d 646; Cole v. Hall, E.D.N.Y.1964, 35 F.R.D. 4. See also Cox v. Hutcheson, S.D.Ind.1962, 204 F.Supp. 442.
The uniform current of authority in this Circuit has been to limit the jurisdiction of the District Courts under the Labor-Management Reporting and Disclosure Act to suits based upon allegations that a labor organization or officer or agent thereof acting in his official capacity violated the terms of the Act. Thus it has been consistently held that the Labor-Management Reporting and Disclosure Act regulates only the relationship between the union and its members and not that between an employer and his employees. See Cafero v. New York Typographical Union, S.D.N.Y. 1963, 47 C.C.H.Lab.Cas. 18,267; Fogg v. Randolph, S.D.N.Y.1962, 244 F.Supp. 885, 888; Gross v. Kennedy, S.D.N.Y. 1960, 183 F.Supp. 750. The legislative history of the statute confirms the correctness of these decisions. See Tomko v. Hilbert, 3 Cir., 1961, 288 F.2d 625. Rulings elsewhere are to the same effect. See Rinker v. Local No. 24, Amalgamated Lithographers, W.D.Pa.1962, 201 F.Supp. 204, appeal dismissed, 3 Cir., 1963, 313 F.2d 956; Bennett v. Hoisting & Portable Engineers, D.Or.1960, 207 F.Supp. 361; Strauss v. International Bhd. of Teamsters, E.D.Pa.1959, 179 F.Supp. 297.
Accordingly, we affirm the dismissal of the second count of the complaint for lack of jurisdiction over subject matter.9
IV.
The motion for a preliminary injunction was properly denied by the District Court for failure to show that *146irreparable injury would result or that money damages would be insufficient should appellants ultimately prevail. This alone was sufficient basis for denial of the injunction. But in addition there was no demonstration of a likelihood of success which would warrant such provisional relief.
In view of the conclusions at which we have arrived, we find it unnecessary to discuss various other miscellaneous contentions of the parties, including the argument made by the Railroad that indispensable parties, namely the Brotherhood and the 52 Mott Haven Yard transferees, were not before the Court.
Affirmed, except that the case is remanded to the District Court for the Southern District of New York with a direction that summary judgment be entered in favor of the Railroad dismissing the first count of the complaint for lack of subject matter jurisdiction.
. Rule 12(b).
* * * [I]f, on a motion asserting tbe defense numbered (6) to dismiss for failure of the pleading to state a claim upon which relief can be granted, matters outside the pleading are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and disposed of as provided in Rule 56, and all parties shall be given reasonable opportunity to present all material made pertinent to such a motion by Rule 56.
. Rule 29 of the pre-1962 agreements reads as follows:
(a) In event of a reduction of force at any point and a shortage of help existing at any other point, employees laid off will have preference over men not in tbe employ of the company. The appropriate officials shall notify the General Chairmen of the respective crafts of the number of men needed at point where shortages exist, the General Chairmen to notify the furloughed employees so they may take advantage of the opportunity to transfer.
(b) Employees transferring under this rule, whether taking the place of an absentee, filling a vacancy or a new job, shall take rank behind all employees in service at the point to which transferred and will retain seniority at the point from which transferred until 30 days after date of restoration of forces at point of former employment, seniority to govern.
. The agreement provided for the abolition of 76 positions for carmen, car cleaners, carmen helpers and sheet metal workers at Mott Haven, and for the creation of 57 new positions at Grand Central Terminal. This number of new positions was one more than the Railroad had originally proposed, as one additional opening for a sheet metal worker was created as a result of the negotiations.
. See Footnote 2 supra.
. The proofs submitted in opposition to the motion for a preliminary injunction, however, establish that implementing agreements, in the post-1964 period as well as during the years 1962-1964, uniformly provided for the preservation of full accumulated seniority in cases of “coordination.”
. The 1964 national agreement provides for a Shop Craft Special Board of Adjustment, set up in accordance with the Railway Labor Act, 45 U.S.C., § 153, Second, which “shall have exclusive jurisdiction over disputes between the parties growing out of grievances concerning the interpretation or application of Article I, Employee Protection * * But this does not seem to cover disputes between individual employees or groups of employees, who are not “parties” to the 1964 contract, and a carrier. Thus, the proper body to interpret the contracts in question is probably the National Railroad Adjustment Board which is empowered to handle “disputes between an employee or group of employees and a carrier or carriers growing out of grievances or out of the interpretation or application of agreements concerning * * * rules, or working conditions * * *.” 45 U.S.C., § 153, First (i).
. There is no doubt that individual employees, such as the plaintiffs here, whose interests vis-á-vis their employer are hostile to those of their union, have standing to present grievances to the Adjustment Board, irrespective of the union’s position. The discussion to the contrary in Steele v. Louisville & Nashville R.R., 1944, 323 U.S. 192, 205-206, 65 S.Ct. 226, 89 L.Ed. 173, is no longer valid. See Elgin, Joliet & Eastern Ry. v. Burley, 1945, 325 U.S. 711, 731-738, 65 S.Ct. 1282, 89 L.Ed. 1886, aff’d on rehearing, 1946, 327 U.S. 661, 66 S.Ct. 721, 90 L.Ed. 928; Conley v. Gibson, 1957, 355 U.S. 41, 47, 78 S.Ct. 99, 2 L.Ed.2d 80. See also Starke v. New York C. & St. L. R.R., 7 Cir., 1950, 180 F.2d 569, 573; Spires v. Southern Ry., 4 Cir., 1953, 204 F.2d 453; Colbert v. Brotherhood of R.R. Trainmen, 9 Cir., 1953, 206 F.2d 9, 12, cert. denied, 1954, 346 U.S. 931, 74 S.Ct. 320; Gainey v. Brotherhood of Railway, etc., Clerks, 3 Cir., 1960, 275 F.2d 342.
. As the Brotherhood was not served with copies of the motion papers, the situation we have to deal with on this appeal is anomalous. Of course the claim in count one against the Brotherhood is inextricably bound up with the claim in count one against the Railroad. It is, nevertheless, clear: (1) that the conclusory allegations of conspiracy and collusion, even if interpreted as charging “hostile” discrimination, must fail on summary judgment because of the absence of proofs in the affidavits to support such a charge; and (2) that if the Adjustment Board interprets the 1964 agreement as compelling the implementing agreement now under attack, the whole stack of cards must fall. This inevitably affects the Brotherhood as well as the Railroad. As we have no subject matter jurisdiction over the claim against the Railroad, and the Brotherhood is not before us on this appeal, we have no power or authority to make any adjudication against the Brotherhood. It should also be noted that, despite the implication in the dissent, Cunningham v. Erie R.R., 2 Cir., 1959, 266 F.2d 411 is not inconsistent with our decision here. Cunningham’s claim against his employer was based on the breach of an explicit duty under the Railway Labor Act not to discharge a man under a union shop provision for a “reason other than the failure * * * to tender the periodic dues * * * uniformly required as a condition of * * * retaining membership.” 45 U.S.C. § 152, Eleventh. See also Cunningham v. Erie R. R., 2 Cir., 1966, 358 F.2d 640; Ferro v. Railway Exp. Agency, Inc., 2 Cir., 1961, 296 F.2d 847, 851-852. Moreover, as a general proposition, we would be inclined to agree that, in more or less integrated transactions, it is better to retain the Railroad as a party. To prolong this controversy, however, would, we think, be a waste of time for all concerned.
. As the legal issues between appellants and the Brotherhood are not before us, and we have determined that there is no subject matter jurisdiction over the claim in the second count against the Railroad, we do not reach the question discussed in the dissent on the subject of whether contract provisions negotiated by an employer and a union bargaining representative can constitute “discipline” within the meaning of the Sections of the Labor-Management Reporting and Disclosure Act relied upon by appellants. 29 U.S.C. §§ 411(a) (5) and 529.
