MUNSON, District Judge:
This case presents us with two issues. The first is whether a decision arising from a statutorily imposed arbitration proceeding can be the basis for collateral estoppel in a subsequent federal court proceeding. If that is permissible, then we must decide whether the use of collateral estoppel violates plaintiffs’ seventh amendment right to a jury trial.
BACKGROUND
At stake in the litigation before us are severance benefits. Plaintiffs are former non-union employees of the defendant Eastern Weighing and Inspection Bureau (“EWIB”). The other defendants in this action are the Traffic Executive Association Eastern Railroads (“TEA-ER”) and the Eastern Railroad Association (“ERA”). [109]*109The relationship among the three defendants is unclear. On the one hand, plaintiffs state that the TEA-ER operated as part of and for the ERA and that the EWIB fell under the TEA-ER. Defendants, on the other hand, state that the TEA-ER and ERA are parent and sister organizations of the EWIB. However, they do not specify which is the parent and which is the sister.
Plaintiffs lost their jobs when one of the defendants — according to plaintiffs it was the TEA-ER, while defendants identify the ERA — eliminated the EWIB. As a result, plaintiffs started this class action claiming entitlement to benefits under § 219(g) of the Staggers Rail Act of 1980 (“Staggers Act”).1 49 U.S.C. § 10706 note; Pub.L. No. 96-448, 94 Stat. 1895, 1928. The § 219(g) benefits (also referred to as “New York Dock conditions”)2 would be vastly more remunerative than the severance payments offered the plaintiffs.3 The complaint contained four counts. Count I was the Staggers Act claim; Counts II through IV alleged fraud, breach of fiduciary duty, and violation of the Racketeering Influenced and Corrupt Organizations Act ("RICO”), 18 U.S.C. § 1961 et seq.
Following commencement of this action, defendants moved to compel arbitration on the Staggers Act claim. The employees agreed to submit that count to binding arbitration on a classwide basis. Both parties set up informal procedural rules to govern the arbitration proceeding. They agreed to presentation of oral or written testimony, to extensive briefing and did, in fact, engage in informal discovery. At the hearing the plaintiffs cross-examined the defendants’ witnesses who testified orally, and could have, if they had chosen, called in and cross-examined those witnesses who submitted their testimony on paper. The agreement acknowledged that plaintiffs would not waive their right to have the district court decide Counts II through IV.
The arbitration board ruled two to one that the plaintiffs were not entitled to Staggers Act benefits. To qualify for the Staggers Act entitlement the plaintiffs would have had to be “employees of [a] rate bureau.” 49 U.S.C. § 10706 note. Central to the decision, and this appeal, was the arbitration board’s express finding that the plaintiffs were not rate bureau employees.
The court below affirmed the arbitrator’s decision. 688 F.Supp. 903 (S.D.N.Y.1988).4 It denied the plaintiffs’ motion for a trial de novo on Count I. Then the court utilized the doctrine of collateral estoppel to grant summary judgment in favor of the [110]*110defendants on Counts II through IV. The district court held — and neither party disputes — that the only way plaintiffs could prevail on Counts II through IV would be to prove that they were rate bureau employees as defined by the Staggers Act. The court below reasoned that since it endorsed the arbitration decision which determined plaintiffs were not rate bureau employees, it was estopped from deciding whether the plaintiffs’ status, for the purposes of Counts II-IV, was that of rate bureau employees.
On appeal, plaintiffs do not challenge the district court’s refusal to grant a trial de novo on Count I. They do challenge the decision to grant summary judgment in favor of the defendants on Counts II through IV.
DISCUSSION
I. Collateral estoppel.
We must first consider whether collateral estoppel is applicable to the finding made in the arbitration decision. Although they have different positions on when collateral estoppel is applicable, both sides recognize that the findings of arbitration boards can serve as the basis for collateral estoppel in a federal court proceeding.
Plaintiffs argue that because the ev-identiary standards for the arbitration proceeding were not as strict as they would be under the Federal Rules of Evidence, the issue decided by the arbitration board should not have preclusive effect on the counts to be decided by a federal court. See Parklane Hosiery Co. v. Shore, 439 U.S. 322, 331 n. 15, 99 S.Ct. 645, 651 n. 15, 58 L.Ed.2d 552 (1979) (“differences in available procedures may sometimes justify not allowing a prior judgment to have estoppel effect in a subsequent action even between the same parties”). We do not agree with plaintiffs’ position. The parties’ agreement to arbitrate outlined procedures to be followed. There is no indication that plaintiff sought to include any evidentiary standard or procedure which defendants refused to accept. More importantly, plaintiffs have not shown how the procedures were improper to the extent that the arbitration board could not make a reasoned decision; nor have they shown they were unfairly prejudiced by the procedures used.5 See SCAC Transport (USA) Inc. v. S.S. “Danaos”, 845 F.2d 1157, 1163 (2d Cir.1988); compare Parklane Hosiery Co., 439 U.S. at 331 n. 15, 99 S.Ct. at 651 n. 15 (“If, for example, the defendant in the first action was forced to defend in an inconvenient forum and therefore was unable to engage in full scale discovery or call witnesses, application of offensive collateral estoppel may be unwarranted.”). In short, plaintiffs had a full and fair opportunity to litigate the issue before the arbitration board. See Blonder-Tongue Laboratories, Inc. v. University of Illinois Found., 402 U.S. 313, 328, 91 S.Ct. 1434, 1442, 28 L.Ed.2d 788 (1971).
The policies behind collateral estoppel counsel for its use in this instance. As the Supreme Court has observed, “[t]o preclude parties from contesting matters that they have had a full and fair opportunity to litigate protects their adversaries from the expense and vexation attending multiple lawsuits, conserves judicial resources, and fosters reliance on judicial action by minimizing the possibility of inconsistent decisions.” Montana v. United States, 440 U.S. 147, 153-54, 99 S.Ct. 970, 973-74, 59 L.Ed.2d 210 (1979). If the district court had not granted defendants’ summary judgment motion, it would have left open the possibility for a result where the employees were not rate bureau employees under Count I, but were rate bureau employees under Counts II through IV. Such a conflict would be confusing and irrecon[111]*111cilable. Additionally, given plaintiffs’ full and fair opportunity to litigate the issue of whether they were rate bureau employees, we feel that, for reasons of conserving resources and fostering finality, it was proper to apply collateral estoppel to avoid relitigation of the arbitration board’s finding. See Blonder-Tongue Laboratories, Inc., 402 U.S. at 328, 91 S.Ct. at 1442. In sum, we conclude that the district court properly applied collateral estoppel when it granted summary judgment for the defendants on Counts II through IV.
Our conclusion is not swayed by our recent decision that arbitration proceedings were not res judicata over a fired employee’s action brought under 42 U.S.C. § 1983. Coppinger v. Metro-North Commuter R.R., 861 F.2d 33 (2d Cir.1988). The plaintiff, Ronald Coppinger, was a former employee of Metro-North Commuter Railroad (“Metro-North”). He was fired after urinalysis confirmed the presence of illegal substances in his body. Coppinger sought to have his dismissal vacated and, pursuant to the Railway Labor Act (“RLA”), 45 U.S. C. § 151 et seq., he submitted his case to compulsory and binding arbitration. The arbitration board upheld Coppinger’s dismissal.
Subsequently, Coppinger filed a civil rights action in the Southern District of New York under 42 U.S.C. § 1983. In his complaint Coppinger alleged, among other things, that Metro-North infringed on his fourth amendment rights. The district court in that case dismissed his § 1983 claim holding that it lacked jurisdiction because Coppinger’s claims fell within the arbitration board’s exclusive and primary jurisdiction.
We reversed the district court insofar as it had held that it did not have jurisdiction to hear Coppinger’s complaint. As an initial matter, we held that Coppinger had made out a colorable fourth amendment claim. Next, we concluded that the district court did have jurisdiction over the § 1983 claim. Then, with language which might appear to conflict with this opinion, we held that proceedings before the arbitration board were not res judicata over plaintiff’s § 1983 claim.6
Our primary holding in Coppinger was that the district court had jurisdiction over the § 1983 claim. In the case at bar the parties have taken for granted that the district court had jurisdiction over Counts II, III and IV. Thus, in both cases the arbitration proceedings do not deprive the district courts of jurisdiction over related claims in which arbitration was not mandated. See Atchison, Topeka and Santa Fe Ry. Co. v. Buell, 480 U.S. 557, 107 S.Ct. 1410, 94 L.Ed.2d 563 (1987) (arbitration of a grievance pursuant to the RLA does not deprive district court of jurisdiction over a related personal injury claim brought under the Federal Employers’ Liability Act, 45 U.S.C. § 51 et seq.).
Nonetheless, in Coppinger we refused to give an arbitration decision preclusive effect and today we grant preclusive effect to an arbitration decision. An explanation for the different results lies in the different nature of the preclusion sought in each case. In Coppinger the defendant sought to use the arbitration decision as res judica-ta. “Under res judicata, a final judgment on the merits bars further claims by parties or their privies from relitigating issues that were or could have been raised in that action.” Kremer v. Chemical Construction Corp., 456 U.S. 461, 466-67 n. 6, 102 S.Ct. 1883, 1889-90 n. 6, 72 L.Ed.2d 262 (1982). In contrast, our decision today invokes collateral estoppel. “Under collateral estoppel, once a court decides an issue of fact or law necessary to its judgment, that decision precludes relitigation of the same issue on a different cause of action between the same parties.” Id. It follows that, “[a]s compared to claim preclusion, the rules of issue preclusion do not purport to prohibit litigation of matters that never have been argued or decided.” 18 C. Wright, A. Miller & E. Cooper, Federal [112]*112Practice and Procedure § 4416, at 136 (1981).
Because of the difference between collateral estoppel and res judicata, invoking collateral estoppel in a given case may be permissible when invoking res judicata is not. Thus, the Seventh Circuit has held in the prisoners’ rights context that, while res judicata does not apply to an individual class member’s claims brought subsequent to a class action, collateral estoppel does apply. Crowder v. Lash, 687 F.2d 996, 1007-11 (7th Cir.1982). Courts will apply collateral estoppel and not res judicata because the values of avoiding embarrassing inconsistencies and avoiding burdening a court and an adversary with repetitious litigation are “served more directly by issue preclusion than by claim preclusion.” 18 C. Wright, A. Miller & E. Cooper, Federal Practice and Procedure § 4416, at 139 (1981). Therefore, we do not think it at all unusual in one case to grant an arbitral finding collateral estoppel effect, and in another to deny an arbitral decision res judicata effect.
In part the decision arrived at in Cop-pinger stemmed from a hesitancy to permit arbitration to preclude from the district court’s consideration matters never argued or decided. See Coppinger, 861 F.2d at 36-37. This was one of the considerations which guided the Supreme Court’s decision to refuse to grant an arbitration decision preclusive effect over a Title VII claim. Alexander v. Gardner-Denver Co., 415 U.S. 36, 94 S.Ct. 1011, 39 L.Ed.2d 147 (1974). The Court reasoned that the statutory right was independent of the contractual right resolved in arbitration. Id. at 52,94 S.Ct. at 1021. To have granted the arbitration decision res judicata effect would have taken a determination regarding one right and improperly allowed that to dictate the determination regarding another right. Likewise, if we had invoked res judicata in Coppinger, we would have taken the finding that Copping-er was not improperly discharged and from that concluded that he had not presented any valid constitutional claims. We refused to proceed in that manner and preclude claims never argued or decided. In the case at bar, however, the preclusion extended covers only an issue which the arbitration board decided, namely, that plaintiffs were not rate bureau employees.
Other considerations guided our decision in Coppinger. In our assessment the arbitrators there lacked the authority, lacked the competence and failed to provide the protective procedures necessary to fairly adjudicate a § 1983 lawsuit. First, with regard to the arbitrators’ authority, under the RLA their primary concerns were contractual, rather than constitutional or statutory, rights. Coppinger, 861 F.2d at 38-39; compare Greenblatt v. Drexel Burnham Lambert, Inc., 763 F.2d 1352, 1361 (11th Cir.1985) (arbitration board properly considered and determined allegations based in state law and. contractual rights). Furthermore, the relief they could provide was limited to back pay and reinstatement. Coppinger, 861 F.2d at 39. Hence we were unwilling to permit the district court to extend the board’s determination to cover, as though raised in the dispute before the board, rights over which the board could not grant relief. In the case at bar the district court did not, in like manner, stretch out of proportion the power of the arbitrators. It granted collateral estoppel effect to a finding which was within the arbitration board’s purview.
Second, in Coppinger we also questioned the competence of arbitrators to determine legal and factual issues raiáed under the fourth amendment and under § 1983. In contradistinction, competence of arbitrators is not at issue in the case at bar. Plaintiffs do not question the expertise nor the competence of the arbitrators who determined that plaintiffs are not rate bureau employees.7
Third, we perceived in Coppinger that arbitral procedures did not protect constitutional guarantees as adequately as fed[113]*113eral court procedures.8 We noted that “ar-bitral fact-finding is not the equivalent of judicial fact-finding.” Coppinger, 861 F.2d at 39, and cited examples, e.g., lack of jury trial in arbitration, limited judicial review, etc. Nonetheless, we are of the opinion that collateral estoppel is properly applicable in the situation before us.
The issue on which the arbitration board found against plaintiffs was not a constitutional issue. In Coppinger, though, we were particularly concerned that “where suits are tried” is important when the “rights sought to be vindicated ... entail the interpretation and application of both the New York and Federal Constitution.” Coppinger, 861 F.2d at 39. Today we do not grant preclusive effect to an arbitral decision which interpreted and applied constitutional rights; instead we grant preclusive effect to a decision which, pursuant to a Congressional mandate, applied federal statutory law. Moreover, the nature of the issue decided by the arbitration board— whether or not plaintiffs were rate bureau employees — is much more akin to the law of the shop than is the question of whether an individual’s fourth amendment right against unreasonable search and seizure has been violated. Cf Coppinger, 861 F.2d at 38 (citing Alexander, 415 U.S. at 57, 94 S.Ct. at 1024).
We also believe that the procedures utilized by the arbitration board in the case at bar compare favorably when contrasted with the shortcomings of arbitral procedures listed in Coppinger. Even though the parties in this case did not follow the Federal Rules of Evidence or Civil Procedure, they did agree, as indicated above, to the procedures which would be followed in the arbitration proceedings. Moreover, the record nowhere indicates that plaintiffs sought a particular procedure and were denied it. While cross-examination may be limited in arbitral proceedings, witnesses who testified before the board either orally or on paper could have been cross-examined by the adversarial parties, if the parties had chosen. Contrary to another of the shortcomings catalogued in Coppinger, the arbitration decision at issue here was presented in a reasoned, detailed opinion. See SCAC Transport, 845 F.2d at 1163. Finally — and we address this in much greater detail later, if we were to carry to its full extent the admonition in Coppinger that arbitration proceedings do not carry a right to a jury trial, we would find ourselves in conflict with the Supreme Court’s Parklane decision which held that a jury trial in a prior proceeding is not a prerequisite to granting the prior proceeding pre-clusive effect over a subsequent proceeding to which a jury trial right attaches. 439 U.S. at 333-35, 99 S.Ct. at 652-54.
In Coppinger we took our cue from the Supreme Court which, on account of the procedures used in arbitration, has been reluctant to grant arbitration findings preclusive effect over certain federal statutory and constitutional rights. See, e.g., McDonald v. West Branch, 466 U.S. 284, 104 S.Ct. 1799, 80 L.Ed.2d 302 (1984) (arbitration decision does not have preclusive effect over a § 1983 claim); Alexander v. Gardner-Denver Co., 415 U.S. 36, 94 S.Ct. 1011, 39 L.Ed.2d 147 (1974) (arbitration decision does not have preclusive effect over a Title VII claim). Despite its hesitancy, the Supreme Court expressly has not foreclosed federal courts from granting preclu-sive effect to arbitration decisions. Dean Witter Reynolds, Inc. v. Byrd, 470 U.S. 213, 223, 105 S.Ct. 1238, 1243, 84 L.Ed.2d 158 (1985). In making our determination we are to “take into account the federal interests warranting protection.” Id.9
[114]*114The Eleventh Circuit has considered those federal interests and has held that arbitration findings may be given collateral estoppel effect over issues in a RICO claim. Greenblatt v. Drexel Burnham Lambert, Inc., 763 F.2d 1352 (11th Cir.1985). In Greenblatt, contrary to the case at bar, the report of the arbitration board contained no specific factual findings. See id. at 1361. Despite this absence, the court inferred from the arbitration decision factual findings upon which decision must have been predicated. With these inferences made, the court did not “think it improper to grant collateral estoppel effect to an arbitration panel’s factual findings regarding [the] underlying acts” upon which the RICO claim was based, provided the arbitrators’ findings were within their authority and expertise. Id. We feel a similar conclusion is appropriate in the case at bar. As noted, underlying each of Counts II through IV is the contention that plaintiffs were rate bureau employees. Since there is no question regarding the arbitrators’ authority and since none has been raised regarding their expertise, we likewise do not think it improper to grant collateral estoppel effect to the arbitrators’ factual finding on an issue which underlies Counts II through IV.
While we reembrace the holding of the Coppinger case, we do not believe that the result reached there should govern every case where a court is asked to grant preclu-sive effect to an arbitration decision. To permit the Coppinger result to dictate the result today would require us to overlook the fundamental distinction which divides res judicata from collateral estoppel.
II. Seventh Amendment.
Plaintiffs attack the use of collateral estoppel, arguing that it impinges on their seventh amendment right to a jury trial.10 We do not agree. “[Preclusion may not be defeated simply by showing that there was no right to trial by jury in the first action and that there is a constitutional right to trial by jury in the second action, no matter what anguish that may cause to those who believe in juries.” 18 C. Wright, A. Miller & E. Cooper, Federal Practice and Procedure § 4465, at 600 (1981). The Supreme Court has recognized that there is no seventh amendment violation when a party loses the chance for a jury trial because the trial court invokes collateral estoppel based on conclusions made in a non-jury, equity proceeding. Parklane Hosiery Co. v. Shore, 439 U.S. 322, 99 S.Ct. 645, 58 L.Ed.2d 552 (1979). Furthermore, this court has previously granted preclusive effect to findings made by arbitration boards. See, e.g., American Renaissance Lines, Inc. v. Saxis Steamship Co., 502 F.2d 674, 678-79 (2d Cir.1974) (charter agreement provided for arbitration of disputes; arbitrators’ finding of liability is binding on the parties and the court); Ritchie v. Landau, 475 F.2d 151 (2d Cir.1973) (arbitration pursuant to an employment contract; collateral estoppel is given to the arbitrators’ finding that plaintiff was owed a bonus of $200,000).
But plaintiffs counter that the cases which base collateral estoppel on arbitration proceedings have been cases where the arbitration was contracted for and not mandated by statute. The Staggers Act itself requires that plaintiffs’ claim under that Act be subject to compulsory arbitration. See Walsh v. United States, 723 F.2d at 574 (“the ICC intended ... mandatory arbitration”); New York Dock Ry. v. United States, 609 F.2d at 87-89. Since plaintiffs did not agree in a contract to arbitrate their Staggers Act claim, they argue that [115]*115they did not waive their seventh amendment right to a jury trial, and consequently, that the district court should not have used the arbitration decision as a basis for collateral estoppel.11
Despite the fact that plaintiffs did not contractually waive any right to a jury trial on Counts II through IV, seventh amendment strictures do not apply to those counts. As an initial matter, we note that plaintiffs only have a right to jury trial over issues presented in actions having the nature of suits at common law. See Curtis v. Loether, 415 U.S. 189, 194-95, 94 S.Ct. 1005, 1008-09, 39 L.Ed.2d 260 (1974); see also Dairy Queen, Inc. v. Wood, 369 U.S. 469, 470-73, 82 S.Ct. 894, 896-97, 8 L.Ed.2d 44 (1962). In determining whether a jury trial right attaches to their claims, we must consider “the nature of the issue to be tried rather than the character of the overall action.” Boss v. Bernhard, 396 U.S. 531, 538, 90 S.Ct. 733, 738, 24 L.Ed.2d 729 (1970). While equitable claims escape seventh amendment coverage, Counts II through IV cannot escape the seventh amendment on that basis because they do not present issues equitable in nature. Cf. Ross v. Bernhard, 396 U.S. 531, 90 S.Ct. 733, 24 L.Ed.2d 729 (1970) (shareholder derivative action is subject to seventh amendment strictures). Yet that does not end the inquiry. The court must also consider whether the issue to be tried is part of a “statutory proceeding” which is “not a suit at common law or in the nature of such a suit” or whether it “involves rights and remedies of the sort typically enforced in an action at law.” Curtis v. Loether, 415 U.S. at 194-95, 94 S.Ct. at 1008-09 (plaintiffs have a jury trial right in an action brought to redress violations of the fair housing provisions of the Civil Rights Act of 1968). If the former description fits the issue to be tried, then no seventh amendment right to trial by jury attaches to that issue. Id.; NLBB v. Jones and Laughlin Steel Corp., 301 U.S. 1, 48, 57 S.Ct. 615, 629, 81 L.Ed. 893 (1937) (NLRB’s award of backpay in an unfair labor practice proceeding is not subject to seventh amendment strictures).
The issue of whether plaintiffs were rate bureau employees must be determined in a statutory proceeding which is not in the nature of a suit at common law. When Congress created § 219(g) of the Staggers Act, it “create[d] a new cause of action and remedies unknown to the common law” and “vest[ed] factfinding in a tribunal other than a jury____” Textile Workers Pension Fund v. Standard Dye & Finishing Co., Inc., 725 F.2d 843, 855 (2d Cir.), cert. denied, 467 U.S. 1259, 104 S.Ct. 3554, 82 L.Ed.2d 856 (1984). In Textile Workers this court concluded that the initial decision by pension fund trustees of employers’ withdrawal liabilities under the Multiem-ployer Pension Plan Amendments Act of 1980 (“MPPAA”) did not violate the seventh amendment. Just as with the MPPAA, Congress in § 219(g) of the Staggers Act designated “the use of a special tribunal,” id. at 855, in this case an arbitration board. And as with the MPPAA, Congress set up “detailed procedures,” when it designated the New York Dock conditions [116]*116as applicable to fired rate bureau employees. See id. Those conditions include a 90 day advance notice requirement, the requirement of an implementation agreement, a binding arbitration requirement, a six year protective period, and an express allocation of the burden of proof. See New York Dock Ry. v. United States, 609 F.2d 83, 94-95 (2d Cir.1979). As a result of the nature of the § 219(g) entitlement, the inquiry of whether plaintiffs are rate bureau employees is “free from the strictures of the Seventh Amendment.” Textile Workers, 725 F.2d at 855. In other words, the § 219(g) entitlement goes part and parcel with the arbitration proceeding which determines whether or not there is a § 219(g) entitlement.
In sum, plaintiffs only have a right to a jury trial over issues presented in actions having the nature of suits at common law. Since whether they were rate bureau employees is not, within the context of the seventh amendment, such an issue, plaintiffs have no jury trial right on that question. Therefore, plaintiffs are not entitled to attack on seventh amendment grounds the preclusive effect which the district court gave to the arbitration board’s finding that plaintiffs were not rate bureau employees. The seventh amendment does not command this court to dilute the Congressional directive found in § 219(g) of the Staggers Act by permitting relitigation as to whether plaintiffs were rate bureau employees.
For the foregoing reasons, the judgment of the district court is affirmed.
