General Teamsters Union Local No. 174 (the union) appeals from a summary judgment in its action for breach of contract and to compel arbitration. We have jurisdiction pursuant to 28 U.S.C. § 1291 . We affirm in part, reverse in part, and remand.

I

The union is the exclusive bargaining representative for certain employees of Trick and Murray, Inc. (employer). On December 29, 1980, the parties entered into a three-year collective bargaining agreement, which had provisions for automatic renewal. On March 28, 1984, the employer unilaterally withdrew its recognition of the union, contending that the bargaining unit contained only one employee. On the same day, the employer petitioned the National Labor Relations Board (Board) for decertification of the union. The union then filed an unfair labor practice charge with the Board. The Board dismissed the employer’s petition and refused to issue a complaint as requested by the union, invoking a longstanding policy of refusing to assert jurisdiction over representational disputes involving bargaining units with less than two members.

On November 28, 1984, the union requested that the employer submit the dispute to arbitration. The parties’ collective bargaining agreement contained a detailed grievance and arbitration provision. The employer did not respond. On April 5, 1985, the union filed the instant action, seeking an order to compel arbitration pursuant to section 301 of the Labor Management Relations Act (LMRA), 29 U.S.C. § 185 . A breach of contract claim was added later.

Both sides moved for summary judgment. The district court, citing Teamsters *1420 Union Local 315 v. Great Western Chemical Co., 781 F.2d 764 (9th Cir.1986) (Great Western), ruled that the union had failed to bring the suit to compel arbitration within the applicable six-month limitations period. According to the court, the union’s claim to compel arbitration had accrued when the employer withdrew its recognition of the union. The district court also applied the same six-month statute of limitations to bar the union’s breach of contract action. The union appeals, arguing (1) that our decision in Great Western to apply a six-month statute of limitations to suits to compel arbitration should not be applied retroactively, and (2) that the breach of contract claim should be controlled by Washington’s six-year statute of limitations for actions based upon written contracts.

II

We are faced initially with a jurisdictional question. The employer argues that a federal district court does not have jurisdiction under section 301 over a labor organization representing a single member bargaining unit. The employer relies on language in section 301 which gives the district court jurisdiction over breach of contract actions between “an employer and a labor organization representing employees.” 29 U.S.C. § 185 (a) (emphasis added). The employer argues that because the union allegedly represents only a single employee, section 301’s jurisdictional grant is not applicable. We have, however, already implicitly rejected the employer’s crabbed interpretation of section 301. See, e.g., John S. Griffith Construction Co. v. United Brotherhood of Carpenters, 785 F.2d 706 , 709 (9th Cir.1986) (Griffith) (asserting jurisdiction over action even though bargaining unit contained no members at the time the action was filed); Operating Engineers Pension Trust v. Beck Engineering & Surveying Co., 746 F.2d 557, 565 (9th Cir.1984) (Operating Engineers) (asserting jurisdiction over section 301 action to recover benefits for a single employee bargaining unit). We now hold that a district court can exercise jurisdiction over an action brought under section 301 even though it involves a contract with a labor organization representing less than two employees.

The employer next argues that this is essentially a representational dispute over which the Board has primary jurisdiction. Even if we were to agree with the employer’s categorization, the Board has twice refused to assert its jurisdiction. We have ruled that when an “injured party ... has no acceptable means to invoke the Board’s jurisdiction,” it is permissible for the district court to exercise jurisdiction, even though a dispute may involve a representation issue. Griffith, 785 F.2d at 711, quoting Laborers Health and Welfare Trust Fund v. Kaufman & Broad, Inc., 707 F.2d 412, 415 (9th Cir.1983). The single employee unit is precisely such a case. Operating Engineers, 746 F.2d at 565 . Because of the Board’s consistent refusal to exercise its primary jurisdiction over this case, the district court had jurisdiction pursuant to section 301(c) of the LMRA, 29 U.S.C. § 185 (c).

Ill

There is no federal statute of limitations for actions to compel arbitration brought under section 301 of the LMRA. Where Congress has not enacted a limitation for a federal claim, our task is to “borrow” the most suitable limitations period from some other source. DelCostello v. International Brotherhood of Teamsters, 462 U.S. 151, 158 , 103 S.Ct. 2281, 2287 , 76 L.Ed.2d 476 (1983) (DelCostello). In Great Western, we ruled that certain suits to compel arbitration should be governed by the six-month statute of limitations for actions brought under section 10(b) of the National Labor Relations Act, 29 U.S.C. § 160 (b). 781 F.2d at 769 . Our conclusion was based on the DelCostello analysis which applied the same six-month statute of limitations to a “hybrid” section 301/breach of the duty of fair representation action brought by an employee against his employer and union. See id. at 768-69, citing DelCostello, 462 U.S. at 172 , 103 S.Ct. at 2295 .

Great Western was decided nine months after the union filed the instant *1421 action. Prior to Great Western, we had borrowed the state statute of limitations for the state law claim that was most analogous to a federal action to compel arbitration. The union alleges that, if we did not apply Great Western retroactively, its action to compel arbitration would be timely under the most closely analogous state statute of limitations. The union does not contest the district court’s finding that its claim was untimely under Great Western. Thus, the issue before us is whether Great Western should be applied retroactively to bar the union’s claim to compel arbitration. Whether a decision should be applied retroactively is an issue of law we review de novo. Cf. United States v. McConney, 728 F.2d 1195, 1201 (9th Cir.) (en banc), cert. denied, 469 U.S. 824 , 105 S.Ct. 101 , 83 L.Ed.2d 46 (1984).

Whether we should apply Great Western retroactively should be determined in light of the three factors identified in Chevron Oil Co. v. Huson, 404 U.S. 97 , 92 S.Ct. 349 , 30 L.Ed.2d 296 (1971) (Chevron). First, we must determine whether Great Western established “a new principle of law, either by overruling clear past precedent ... or by deciding an issue of first impression whose resolution was not clearly foreshadowed.” Id. at 106 , 92 S.Ct. at 355 (citations omitted). Second, we decide “ ‘whether the retrospective operation [of the new rule] will further or retard its operation.’ ” Id. at 107 , 92 S.Ct. at 355 (citation omitted). Finally, we look to see whether retroactive operation of the rule will “ ‘produce substantial inequitable results.’ ” Id. (citation omitted).

Turning to the first factor of the Chevron test, it is clear that Great Western was foreshadowed. Twenty-two months before the instant action was filed, and thirty-one months before Great Western, the Supreme Court held in DelCostello that the section 10(b) six-month statute of limitations period was appropriate for “hybrid” section 301/duty of fair representation claims. While DelCostello did not involve a “pure” section 301 action to compel arbitration, the Court observed in a footnote that “even if this action were considered as arising solely under § 301 ... the objections to use of state law and the availability of a well-suited limitations period in § 10(b) would call for application of the [six-month statute of limitations].” Id. at 159 n. 12, 103 S.Ct. at 2287 n. 12. Although dicta, this statement foreshadowed the abandonment of applying state statutes of limitations to section 301 suits to compel arbitration. Soon after DelCostello , the Third Circuit ruled in Federation of Westinghouse Independent Salaried Unions v. Westinghouse Electric Corp., 736 F.2d 896 (3d Cir.1984) (Westinghouse), that the statute of limitations of section 10(b) was appropriate for suits to compel arbitration. Westinghouse was decided on June 12, 1984, less than three months after the employer in this case unilaterally withdrew its recognition of the union. Despite the clear import of Westinghouse, the union waited over ten months to bring the instant action. We draw two conclusions from Westinghouse. First, the fact that both appellate courts that have considered this issue have come to the same conclusion strengthens our view that adoption of the six-month statute of limitations for arbitration suits was foreshadowed by DelCostello . Second, even if Great Western was not clearly foreshadowed, Westinghouse put the union on constructive notice that its prospective claim might be subject to the shorter six month statute of limitations. The union was not a helpless litigant which was ambushed by a sudden change in the law. Rather, the union effectively sat on its rights. In this situation, applying the shorter statute of limitations does not lead to an inequitable result.

The union argues, however, that DelCostello did not foreshadow Great Western because we had rejected this Supreme Court statement, and the use of the section 10(b) six-month statute of limitations, in an action brought after DelCostello to set aside an arbitration decision. The union’s reliance on this case, United Brotherhood of Carpenters v. FMC Corp., 724 F.2d 815 (9th Cir.1984) (FMC), is misplaced. In FMC, we did not dispute the soundness of the proposition in DelCostello’s footnote 12. Instead, we distinguished DelCostello . *1422 We observed that the claim in footnote 12 “closely resembles an unfair labor practice charge because the employee cannot prevail unless he establishes a breach of the duty of fair representation.” FMC, 724 F.2d at 817-18 n. 1. Because the underlying issue resembled an unfair labor practice, it was appropriate to apply the period of limitations from section 10(b). The claim in FMC was different:

FMC, 724 F.2d at 817. Moreover, in FMC we had before us a statute of limitations created by state law specifically designed to govern the vacation of arbitration awards. In contrast, no state statute of limitations directly governed the dispute in DelCostello .

Here, as in DelCostello , no state statute of limitations directly governs because no such statute is designed to expedite the invocation of arbitration. Furthermore, the underlying dispute in this case involves a representation issue and therefore resembles an unfair labor practice. Indeed, the union’s initial approach was to file an unfair labor practice charge, which the Board declined to hear on jurisdictional grounds. Therefore, FMC did not establish that we had rejected the approach in DelCostello’s footnote 12 for cases such as the one before us. We conclude that adoption of the limitations period of section 10(b) for suits to compel arbitration was foreseeable.

The other case relied on by the union, International Association of Machinists v. Aloha Airlines, Inc., 790 F.2d 727 (9th Cir.) (Aloha Airlines), cert. denied, — U.S. -, 107 S.Ct. 400 , 93 L.Ed.2d 354 (1986), is even less applicable. In that case, we declined to apply retroactively our decision to extend DelCostello to actions alleging breach of contract and breach of status quo provisions brought under the Railway Labor Act (RLA), 45 U.S.C. §§ 151-188 . 790 F.2d at 736 . Unlike Del-Costello and Great Western, the action in Aloha Airlines arose under the RLA, not section 301 of the LMRA. The extension of a rule created under the LMRA to the RLA was not clearly foreshadowed. Id. (“it extends the rationale in DelCostello to cases arising under the RLA, a question which we have not previously addressed”). The case before us, Great Western, and DelCostello all arose under the LMRA.

Applying the second Chevron factor, whether retroactive operation of Great Western will further or retard the purposes of its holding, also counsels applying the six-month statute of limitations to this case. The union waited over a year after the employer repudiated the collective bargaining agreement to file this action. Arbitration must “be promptly invoked and promptly administered” because a “long period of controversy and conflict ... can poison the relationship” between the parties. Great Western, 781 F.2d at 766 . The union’s failure to seek promptly to compel arbitration resulted in the exact evils the shorter statute of limitations was designed to avoid.

Turning to the third factor, applying Great Western retroactively is not inequitable. In addition to the factors discussed previously, retroactive application does not leave the union in this case without a remedy. The union can bring a breach of contract action. Furthermore, the union has presented no reasons why it could not have tolled the six-month limitations period by bringing its action to compel arbitration earlier. Therefore, the district court did not err in retroactively applying Great Western’s six-month statute of limitations to bar the union’s claim to compel arbitration.

IV

The union also asserted a second claim under section 301 seeking damages for the employer’s alleged breach of the collective *1423 bargaining agreement. The district court dismissed this claim, stating that it was also barred by the six-month statute of limitations adopted in DelCostello . The union argues that this holding is in conflict with United Auto Workers v. Hoosier Cardinal Corp., 383 U.S. 696 , 86 S.Ct. 1107 , 16 L.Ed.2d 192 (1966) (Hoosier Cardinal). In Hoosier Cardinal, the Court ruled that “straightforward” section 301 suits alleging solely a breach of contract should be governed by the most closely analogous statute of limitations of the forum state. Id. at 704-05 , 86 S.Ct. at 1112-13 . Here, the union argues that the most closely analogous statute of limitations would be Washington’s six-year statute for actions based on written contracts. Wash.Rev. Code § 4.16.040.

The employer argues in reply that Hoosier Cardinal is inapplicable because there was no arbitration clause involved or arbitration claim asserted in that case. Instead, the employer argues, the union’s breach of contract/arbitration claim is a “hybrid” action, both halves of which are governed by DelCostello’s six-month statute of limitations. We are called on, therefore, to determine what statute of limitations should be applied to a breach of contract action brought under section 301 when the plaintiff fails to bring timely suit to compel arbitration under the terms of the parties’ collective bargaining agreement. The selection of an appropriate statute of limitations is a question of law we review de novo. See Aragon v. Federated Department Stores, Inc., 750 F.2d 1447, 1449-50 (9th Cir.), cert. denied, 474 U.S. 902 , 106 S.Ct. 229 , 88 L.Ed.2d 229 (1985).

Contrary to the employer’s claim, the union has not brought a “hybrid” action. The Supreme Court has defined a hybrid action as one brought by an employee “against an employer and a union, alleging that the employer had breached a provision of a collective bargaining agreement, and that the union had breached its duty of fair representation by mishandling the ensuing grievance-and-arbitration proceedings.” DelCostello, 462 U.S. at 154, 165 , 103 S.Ct. at 2285, 2291 . This definition has been used consistently by the Court. See, e.g., Bowen v. United States Postal Service, 459 U.S. 212, 235 , 103 S.Ct. 588, 601 , 74 L.Ed.2d 402 (1983) (White, J., concurring and dissenting); United Parcel Service, Inc. v. Mitchell, 451 U.S. 56, 66 , 101 S.Ct. 1559, 1566 , 67 L.Ed.2d 732 (1981) (Mitchell) (Stewart, J., concurring). Here, the plaintiff is not an individual employee, but rather the union. The union is obviously not alleging that it breached its duty of fair representation. This is not a “hybrid” action, as that term has been defined by the Supreme Court.

More importantly, the reasons relied on by the Court in DelCostello for applying the federal statute of limitations are absent in this case. The primary reason the Court applied the section 10(b) statute of limitations to both parts of the section 301/duty of fair representation claims was that “ ‘the two claims were inextricably interdependent.' ” 462 U.S. at 164-65 ,103 S.Ct. at 2291, quoting Mitchell, 451 U.S. at 66-67 , 101 S.Ct. at 1566 . As the Court explained, to prevail against the union on the duty of fair representation claim, the employee had to establish that the employer breached the employment contract. To prevail against the employer, the employee had to establish that the union breached its duty of fair representation. “The employee may ... sue one defendant and not the other; but the case he must prove is the same whether he sues one, the other, or both.” DelCostello, 462 U.S. at 165 , 103 S.Ct. at 2291 .

The case before us is far different. The claims to compel arbitration and the breach of contract are not interdependent. The union is not alleging that the employer breached its contract by failing to arbitrate. Rather, the union is alleging that the employer's repudiation of the entire collective bargaining agreement constituted a breach of contract. To compel arbitration, the union merely has to establish that the dispute is suitable for arbitration under the terms of the parties’ collective bargaining agreement. United Steel Workers v. Warrior & Gulf Navigation Co., 363 U.S. 574, 582 , 80 S.Ct. 1347, 1353 , 4 L.Ed.2d 1409 (1960); Aloha Airlines, 790 F.2d at 731 . The breach of contract claim, on the *1424 other hand, requires a showing of a valid contract, the terms of which were breached. The two claims are not “inextricably interdependent.” DelCostello, 462 U.S. at 165 , 103 S.Ct. at 2291 . They may be interrelated but they are distinct. A court could find that the employer had a duty to arbitrate, but that there had been no breach of the underlying contract. Alternatively, the employer could have violated a clause in the contract which it had no duty to arbitrate. See, e.g., United Steelworkers v. Phelps Dodge Corp., 764 F.2d 576 , 579 (9th Cir.1985); Frederick Meiswinkel, Inc. v. Laborer’s Union Local 261, 744 F.2d 1374 , 1377 (9th Cir.1984), cert. denied, 470 U.S. 1028 , 105 S.Ct. 1394 , 84 L.Ed.2d 783 (1985). Unlike the plaintiff in DelCostello , the union in this case could prevail on one claim but lose on the other.

The other rationale supporting the Court’s conclusion in DelCostello is also absent in this case. The Court applied the section 10(b) six-month statute of limitations in part because it was “actually designed to accommodate a balance of interests very similar to that at stake here — a statute that is, in fact, an analogy to the present lawsuit more apt than any of the suggested state-law parallels.” 462 U.S. at 169 , 103 S.Ct. at 2293. Despite its holding, the Court cautioned that it did “not mean to suggest that federal courts should eschew use of state limitations periods anytime state law fails to provide a perfect analogy.” Id. at 171, 103 S.Ct. at 2294. Here, the Supreme Court has already ruled that the union’s breach of contract claim “closely resembles an action for breach of contract cognizable at common law.” Hoosier Cardinal, 383 U.S. at 705 n. 7, 86 S.Ct. at 1113 n. 7. Thus, unlike the hybrid suit considered in DelCostello , the claim here has a closely analogous state statute of limitations for us to apply.

That the union’s contract with the employer contained an arbitration clause does not distinguish this case from Hoosier Cardinal. As stated by the Seventh Circuit when faced with a similar situation:

International Union of Elevator Constructors v. Home Elevator Co., 798 F.2d 222, 227-28 (7th Cir.1986) (Elevator Constructors ). The Supreme Court has directed us to look first to state law. Because of the close resemblance of the union’s claims to common-law breach of contract, we hold that the rule in Hoosier Cardinal, and not DelCostello , should be applied to the union’s breach of contract claim.

Contrary to the employer’s argument, our conclusion does not violate labor law policy. While rapid resolution of labor disputes is generally desirable, see, e.g., Great Western, 781 F.2d at 766 , this policy has less importance, where, as here, the bargaining relationship between the parties has broken down. The parties could have maintained the relationship if the employer had submitted to arbitration or if the union had brought a timely suit to compel arbitration. But those opportunities having past, the six-month statute of limitations urged by the employer “would not serve to protect the bargaining relationship or the collective bargaining agreement.” Elevator Constructors, 798 F.2d at 228 n. 5.

We are sympathetic with the district court’s concern that applying Hoosier Cardinal has the “anomalous” result of creating a different limitations period for a suit to compel arbitration than for a breach of contract claim that conceivably could have been resolved through the arbitration process. In any event, to the extent the result is anomalous, it is required by the Supreme Court’s decision in Hoosier Cardinal. Therefore, we remand this case to the district court for further consideration of the union’s section 301 breach of contract claim, including the selection of the most appropriate state statute of limitations.

AFFIRMED IN PART, REVERSED IN PART, AND REMANDED.
