This case centers upon a claim by appellant, International Brotherhood of Electrical Workers, Local 481, that appellee, Sign-Craft, Inc., improperly repudiated the mul-ti-employer collective bargaining agreement between the Union and the Sign Industry Employer’s Association (SIEA). From June, 1981 through May 31, 1983 Sign-Craft had been a party to the multi-employer agreement between IBEW Local 481 and the Indianapolis Sign Association, which was the predecessor to the disputed IBEW-SIEA agreement. This controversy arose as a result of Sign-Craft’s decision to cease operations within the Indianapolis area and its purported withdrawal from the multi-employer association now represented by the SIEA.
The record reveals that as a result of Sign-Craft’s alleged repudiation of the IBEW-SIEA agreement, appellant Union filed an unfair labor practice charge with the National Labor Relations Board (NLRB) on November 19, 1983. That charge claimed that Sign-Craft had violated §§ 8(a)(1), 8(a)(3) and 8(a)(5) of the Labor Management Relations Act (LMRA). In a letter and summary report dated December 29, 1983, the NLRB Regional Director refused to issue an unfair labor practice complaint and dismissed the unfair labor practice charge.
No grievance was filed by the Union as a result of Sign-Craft’s actions. However, on January 27, 1986, the Union brought the present action against Sign-Craft in the district court under 29 U.S.C. § 185(a) (§ 301(a) of the LMRA). Sign-Craft moved for summary judgment, asserting, inter alia, that the district court lacked subject matter jurisdiction. The district court granted Sign-Craft’s motion, treating it as a motion to dismiss, and dismissed the Union’s cause of action, without prejudice, for lack of subject matter jurisdiction. The IBEW Local 481 appeals that dismissal.

In dismissing appellant’s cause of action, the district court observed:
While the Union would have the Court view the question of whether the agreement validly binds Sign-Craft as merely incidental to the ultimate question of contract violation, such a view is contrary to the posture of the complaint. The Union alleges in its complaint that Sign-Craft has consistently ignored the terms of the agreement, and for that reason, requests declaratory and injunctive relief. In this context, the request for damages should the Court find the agreement binding on Sign-Craft is incidental to the question of validity, rather than vice-versa, [sic]
Proceeding from this characterization of the complaint, the district court concluded that because “the ultimate question for disposition is one of contract validity” the holding in NDK Corporation v. Local 1550 of the United Food and Commercial Workers International Union, 709 F.2d 491 (7th Cir.1983), obliged it to dismiss the Union’s cause of action for lack of subject matter jurisdiction. Appellant Union contends that this conclusion by the district court was error.

NDK involved an employer attempt to bring suit under § 301(a) of the LMRA to rescind a collective bargaining agreement and stay a contractual grievance arbitration proceeding under that agreement. The employer’s action did not allege that a violation of the collective bargaining agreement had occurred. Rather, it claimed that the agreement was invalid because it had been procured by the union through a fraudulent promise that the contract’s terms would not be enforced. In dismissing the employer’s suit for lack of subject matter jurisdiction, our Court expressed its intention to “adhere to the plain language of § 301” and held that the statutory provision “provides jurisdiction for suits for violations of contracts but not for determinations of the validity of contracts where validity is the ultimate issue.” NDK, 709 F.2d at 493.
The opinion in NDK takes care to distinguish its holding from the result reached in Mogge v. District No. 8, International Association of Machinists, 387 F.2d 880 (7th *912Cir.1967), cert. denied, 391 U.S. 936, 88 S.Ct. 1849, 20 L.Ed.2d 855 (1968). In Mogge, a union was sued in its capacity as an employer by a second union that represented its clerical employees. The suit sought damages for the allegedly improper discharge of a clerical worker by the employer union. The employer union had previously refused to arbitrate the matter based on a claim that the collective bargaining agreement it had consummated with the representative union was not valid. It raised that same contention as a defense to the representative union’s suit for damages and alternatively requested that the court proceedings be stayed pending contractual arbitration.
The district court determined that the agreement was valid and stayed court proceedings pending arbitration under the collective bargaining agreement. On appeal our Court rejected the claim by the representative union that the employer union had waived its right to arbitration. We affirmed the district court, holding that the employer union “had the right to a judicial determination of the threshold question of validity before being required to proceed with arbitration.” NDK, 709 F.2d at 493.
The opinion in NDK notes the following differences between the fact situation in that case and the facts of Mogge. First, the plaintiffs in Mogge brought a suit alleging a violation of a valid collective bargaining agreement, a matter clearly within the purview of § 301. Second, the “right” to a judicial determination of the validity of a collective bargaining agreement referred to in Mogge was no more than the right of an employer (or a union) to have that determination made without being deemed to have effectively waived contractual arbitration. Third, the contract validity issue in Mogge was “merely a threshold question” which the court had to resolve before it could determine if there was a violation of the contract. Thus, because the suit before it did not allege the violation of a collective bargaining agreement and since the question of contract validity was in fact the ultimate issue in the case, the NDK court did not believe itself constrained by Mogge. NDK, 709 F.2d at 493.

The sole issue before us is whether the district court properly determined that it lacked subject matter jurisdiction under § 301(a) of the LMRA to hear the Union’s suit. Our review of that decision is de novo. See Huettig v. Landscape Contractors Council of Northern California, 790 F.2d 1421, 1425 (9th Cir.1986). Section 301(a) provides:
Suits for violation of contracts between an employer and a labor organization representing employees in an industry affecting commerce as defined in this chapter, or between any such labor organizations, may be brought in any district court of the United States having jurisdiction of the parties, without respect to the amount in controversy or without regard to the citizenship of the parties.
It is clear that a plaintiff union seeking to bring a cause of action against an employer under § 301 must allege the violation of an existing or valid collective bargaining agreement in order for a federal district court to properly assert jurisdiction. See NDK, 709 F.2d at 493. See also A.T. Massey Coal Company, Inc. v. International Union, United Mine Workers of America, 799 F.2d 142, 146 (4th Cir.1986), cert. denied, — U.S. —, 107 S.Ct. 1964, 95 L.Ed.2d 536 (1987) (holding that a plaintiff must allege a breach of an existing collective bargaining agreement in order to avail itself of jurisdiction under § 301); Leskiw v. Local 1470, International Brotherhood of Electrical Workers, 464 F.2d 721, 723 (3d Cir.1972) (“Section 301(a) only creates federal jurisdiction, in the absence of diversity of citizenship, with respect to suits for violation of contracts between an employer and a labor organization ... or between any such labor organizations.”).
It is equally clear that § 301 grants jurisdiction to the federal district courts to decide the question of whether there is a valid contract between an employer and a union, as long as that determination of the validity or existence of a collective bargaining agreement between the two litigants is *913a threshold issue to a contract enforcement action. See NDK, 709 F.2d at 493; Mogge, 387 F.2d at 883; International Union of Operating Engineers, Local 150 v. G. Bliudzius Contractors, Inc., 730 F.2d 1093 (7th Cir.1984) (holding that a defendant employer was bound by a collective bargaining agreement negotiated by the employer association to which it belonged and ordering the employer to proceed to arbitration under that agreement). See also A.T. Massey, 799 F.2d at 146; Hernandez v. National Packing Co., 455 F.2d 1252, 1253 (1st Cir.1972). However, as noted above, we unequivocally held in NDK that absent an action for enforcement of a contract that is the primary, ultimate thrust of a suit brought under § 301, there is no separate right to a judicial determination of the validity of a collective bargaining agreement under that statutory provision.
The district court analyzed the complaint brought by the Union and concluded that the “posture of the complaint” (i.e., its allegation that “Sign-Craft has consistently ignored the terms of the agreement,” and the fact that for that reason, the Union in this action requests declaratory and in-junctive relief) indicated that “the request for damages should the Court find the agreement binding on Sign-Craft is incidental to the question of validity, rather than vice-versa.” Our task on appeal is to determine if the district court properly characterized the Union’s complaint. In other words, we must ascertain if the validity of the IBEW-SIEA collective bargaining agreement between Sign-Craft and the Union is the ultimate issue raised by the Union’s suit, or alternatively, if that question presents only a threshold determination necessary to the resolution of a central issue of contract enforcement.
The Union’s complaint is styled a “Complaint for Injunctive Relief, Declaratory Relief, and for Damages.” It states the following primary allegations:
1.In June, 1981 Sign-Craft joined the multi-employer association of Indianapolis area sign erection and maintenance firms and thereby agreed to be bound by the predecessor contract to the IBEW-SIEA collective bargaining agreement.
2. Sign-Craft never made an effective withdrawal from the multi-employer association that is a party to the current IBEW-SIEA agreement.
3. In June, 1983 Sign-Craft informed the Union of its intention both to cease operations in the Indianapolis area and to close its Indianapolis facility.
4. Despite those representations to the Union, Sign-Craft continued to perform sign-related work in the geographic area in and around Indianapolis which is covered by the IBEW-SIEA agreement.
In its concluding paragraph, the Union’s complaint expressly requests the following relief:
A. A permanent injunction mandating defendant’s future compliance with all terms of the 1983 Agreement between plaintiff and the SIEA, retroactive to June 1, 1983.
B. A declaratory judgment that defendant is and has been bound by all terms and conditions of the 1983 Agreement between plaintiff and the SIEA, retroactive to June 1, 1983.
C. Damages for breach of contract in an amount to be determined at trial.
D. Such other and further relief as may be deemed proper in the premises, [sic]
The Union’s complaint does not seek to compel arbitration of its dispute with Sign-Craft under the IBEW-SIEA collective bargaining agreement. It does not make reference to any particular provision^) of the agreement that it alleges to have been violated by appellee and fails to specify the amount of damages sought. Clearly, the key questions raised by the Union’s complaint do not go to whether Sign-Craft has committed a violation of an existing collective bargaining agreement, valid between the parties. Rather, the complaint raises questions (i) as to whether Sign-Craft made an effective withdrawal from the multi-employer association it joined in June, 1981, and if not, (ii) whether it has since June, 1983 performed sign-related work within the geographic area covered by the IBEW-SIEA agreement.
*914If it were to proceed to trial, the outcome of this cause of action would turn on a determination of whether Sign-Craft is a party to the IBEW-SIEA agreement. At its core, the complaint simply does not raise the question of whether Sign-Craft violated a valid collective bargaining agreement to which it is a party. Instead, it primarily requests of the district court a determination of whether the IBEW-SIEA agreement is valid between Sign-Craft and the IBEW, and binding on Sign-Craft as an employer.
The above reading of the predominant thrust of the complaint in this matter is reinforced by the nature and ordering of the relief it seeks. The Union asks for a declaratory judgment that the IBEW-SIEA agreement is valid between it and appellee and requests the district court to issue an injunction to force Sign-Craft to comply with its terms. The reference to damages for appellee’s purported breach of the agreement is very general and plainly is collateral to the primary relief the complaint requests.
Given the inferences that arise from our independent interpretation of appellant’s complaint, we cannot conclude that the district court erred when it ascertained that the ultimate question for disposition in this cause of action is one of contract validity, with only an incidental prayer for damages. Given that finding, we are compelled by our precedent to hold that the district court did not have subject matter jurisdiction over the present action.1
IV
We acknowledge that NDK may not be our Court’s final word on the several complex jurisdictional issues raised by union and employer efforts to invoke the § 301 LMRA jurisdiction of the federal district courts in cases involving, inter alia, the question of whether a particular employer is bound by the terms of an existing, valid collective bargaining agreement.2 Nevertheless, our analysis leaves us convinced that this case does not require any further extension or elucidation of the existing § 301 law in our Circuit.
The judgment of the district court is AFFIRMED.
. Given our holding that the district court is without subject matter jurisdiction under § 301 of the LMRA, we need not address the issues raised by the parties as to the parallel jurisdiction of the National Labor Relations Board over this dispute.
. Thus, we note that in McNally Pittsburg, Inc. v. International Association of Bridge, Structural & Ornamental Iron Workers, 812 F.2d 615, 617-19 (10th Cir.1987), the Tenth Circuit expressly declined to follow our Court’s holding in NDK v. Local 1550 of the United Food and Commercial Workers International Union, 709 F.2d 491, 493-95 (7th Cir.1983), and found federal district court jurisdiction under § 301 of the LMRA in a declaratory judgment action that addressed only the validity, and not the violation, of a collective bargaining agreement. The more restrictive reading of the scope of the jurisdiction granted the federal courts by § 301(a) that NDK reflects may also conflict with the position taken by the Fourth Circuit in A.T. Massey Coal Co., Inc. v. International Union, United Mine Workers of America, 799 F.2d 142, 146 (4th Cir.1986), cert. denied, — U.S. —, 107 S.Ct. 1964, 95 L.Ed.2d 536 (1987) (finding federal district court jurisdiction under § 301 in a declaratory judgment action seeking a determination that a parent corporation and its affiliated companies were bound by an existing collective bargaining agreement), and the holding by the Eleventh Circuit in Board of Trustees v. Universal Enterprises, Inc., 751 F.2d 1177, 1184 (11th Cir.1985) ("a district court has jurisdiction under Section 301 to make a determination as to whether a collective bargaining agreement in fact exists”).
