JERRY E. SMITH, Circuit Judge:
In this appeal brought pursuant to Fed. R.Civ.P. 23(f), the defendants challenge a class certification. Concluding that the attempted class does not meet the requirements of the applicable rules, we reverse and remand.
I.
This case has its origins in race discrimination claims made against Texaco, Inc. (“Texaco”), and its subsidiaries in Roberts v. Texaco, Inc., 979 F.Supp. 185 (S.D.N.Y. 1997). During that litigation, counsel for Roberts mentioned in briefs that employees of Star Enterprise (“Star”) were considered members of the class; he also made representations to Matthews Smith that Star employees were included. When the Roberts case settled and a settlement class was certified, however, Star employees were written out of the class.1
A short time after the settlement was announced, Smith obtained a state court temporary restraining order prohibiting Star and Texaco from removing or destroying documents; media reports had suggested that they were destroying evidence.2 At this point, the statute of limitations already had expired.
Star then removed the case to federal court. After a hearing, the district court entered preliminary injunctions and document preservation orders that Star and Texaco appealed. This court affirmed.
The plaintiffs have filed a series of amended complaints, including inter alia, claims against Texaco based on agency principles and stemming from its part ownership of Star (through its wholly-owned subsidiaries Texaco Refining and Marketing Incorporated (“TRMI”) and Texaco Refining and Marketing East (“TRMI East”)). TRMI -and its wholly-owned subsidiary TRMI East were included, based on the latter’s role as joint ven-turer in Star. Saudi Refining Incorporated (“SRI”) was joined as the other joint ven-turer in Star. Finally, Arameo Services Company (“ASC”) was joined because it owns SRI.
Plaintiffs, individually and as representatives of a class of approximately two hundred other salaried black employees, allege that defendants discriminated on the basis of race in violation of title VII of the Civil Rights Act of 1964, as amended by the Civil Rights Act of 1991, 42 U.S.C. § 2000e, and the Civil Rights Act of 1871, as amended by the Civil Rights Act of 1991, 42 U.S.C. § 1981. The plaintiffs as[403]*403sert discrimination in promotions, compensation, and other benefits and privileges of employment throughout Star’s facilities in various states.
The allegations involve Star’s evaluation, job posting, and compensation/pay grade systems and promotion practices. Star and Texaco also are accused of creating or permitting the creation of a hostile work environment for black employees.3 The claims focus on the policies’ subjectivity, which allegedly allows defendants to apply the facially-neutral practices in a discriminatory manner. Plaintiffs seek monetary damages including, but not limited to, compensatory and punitive damages. After a hearing, the district court certified the following class:
All African-American employees of Star Enterprise, at any time from March 23, 1991 to the present who have held or who have tried to obtain, a managerial, supervisory, or professional salaried position, and who have been, continue to be, or may in the future be adversely affected by Star’s alleged racially discriminatory employment and practices. The class does not include any hourly individuals who have tried to obtain salary positions.
II.
A.
A district court maintains substantial discretion in determining whether to certify a class. See Jenkins v. Raymark Indus., Inc., 782 F.2d 468, 471-72 (5th Cir.1986). We recognize the essentially factual basis of the certification inquiry and defer to the district court’s inherent power to manage and control pending litigation, so we review certification decisions only for abuse of that discretion. See Pegues v. Miss. State Employment Serv., 699 F.2d 760, 763 (5th Cir.1983). Nonetheless, “[a] district court by definition abuses its discretion when it makes an error of law.” Koon v. United States, 518 U.S. 81, 99-100, 116 S.Ct. 2035, 135 L.Ed.2d 392 (1996). Whether the court applied the correct legal standard is a question subject to de novo review. See Forbush v. J.C. Penney Co., 994 F.2d 1101, 1104 (5th Cir.1993).
B.
As a guide, we compare the causes of action before delving into the specifics of this case. Class actions brought under title VII typically proceed under two theories, disparate impact4 and systemic disparate treatment5; plaintiffs [404]*404advance both. The disparate impact theory is used to challenge a facially-neutral employment policy that affects a protected employee class more harshly. Pouncy v. Prudential Ins. Co. of Am., 668 F.2d 795, 799 (5th Cir.1982). Disparate impact cases in particular, which challenge specific, facially-neutral policies with proof of statistical disparities despite uniform application, implicate class-based claims.
The disparate treatment theory focuses on whether the employer engaged in a “pattern or practice” of intentional discrimination, that is, whether discrimination was the employer’s standard operating procedure rather than a sporadic occurrence. See Teamsters, 431 U.S. at 336, 97 S.Ct. 1843. We previously have upheld class action certifications involving both causes of action.6
Class actions in which an employer engaged in a pattern or practice of intentional discrimination ordinarily are handled in bifurcated proceedings imposing different burdens of proof in the respective phases. See Shipes v. Trinity Indus., 987 F.2d 311, 318 (5th Cir.1993). During the first or “liability” stage, plaintiffs seek to prove a pattern or practice of invidious class-based discrimination. See id. When successful, individual class members benefit from a presumption of equitable pay (i.e., back pay), their entitlement to which is determined during the second or “remedial” stage.
To obtain back pay, class members need only prove that they were denied employment opportunities and the extent of their loss; the burden then shifts to the employer to demonstrate that the denial was for legitimate reasons. See Richardson, 709 F.2d at 1021; see also Teamsters, 431 U.S. at 362, 97 S.Ct. 1843. Although this final determination typically involves individual hearings, see Johnson v. Goodyear Tire & Rubber Co., 491 F.2d 1364, 1375 (5th Cir.1974), courts, until 1991, streamlined the process by employing special masters, see Newberg & Conte, Newberg on Class Actions §§ 24.119-24.121 (3d ed.1992).
The Civil Rights Act of 1991 fundamentally changed the procedures and remedies available under title VII. Inter alia, the act now permits plaintiffs to recover, in cases raising individual disparate treatment and pattern or practice claims, compensatory and punitive damages for unlawful intentional discrimination. See 42 U.S.C. § 1981a(a)(l). Compensatory damages include relief for “future pecuniary losses, emotional pain, suffering, inconve-[405]*405nienee, mental anguish, loss of enjoyment of life, and other nonpecuniary losses.” § 1981a(b)(3). The act also allows punitive damages if the employer discriminated with malice or with reckless indifference to the federally protected rights of an aggrieved individual. § 1981a(b)(l)(2). Damages are capped at $300,000 per plaintiff. See § 1981a(b)(3). Finally, in all cases in which a plaintiff seeks compensatory and punitive damages, either party may demand a jury. See § 1981a(c).
C.
Under Fed.R.CxvP. 23, the various categories of class actions, with their divers requirements, represent a balance struck in each case between the need and efficiency of a class action and the interests of class members to pursue their claims separately or not at all.7 Class actions are categorized according to the nature or effect of the relief sought.
Relevant to this case are the rules governing rule 23(b)(2) and (b)(3) classes. The rule 23(b)(2) class action was intended for cases in which broad, class-wide injunctive or declaratory relief is necessary. See Holmes v. Cont’l Can Co., 706 F.2d 1144, 1155 n. 8 (11th Cir.1983). The rule 23(b)(3) class action exists to dispose of all other cases in which a class action would be “convenient and desirable,” including those involving large-scale, complex litigation for money damages. Amchem, 521 U.S. at 596, 117 S.Ct. 2231.8 Pairing the respective rule 23 categories with specific kinds of relief reflects a concerted effort to respect the variety among class-member interests, which often depends on the natures of the injuries alleged and relief sought.
D.
The four prerequisites of Rule 23(a) are that
(1) the class be so numerous that join-der of all members is impracticable;
(2) there be questions of law or fact common to the class;
(3) the claims or defenses of the representative parties be typical of the claims or defenses of the class; and
(4) the representative parties will fairly and adequately protect the interests of the class.
Rule 23(a); accord Amchem, 521 U.S. at 613, 117 S.Ct. 2231.
1.
A class must be so numerous that “joinder of all members is impracticable.” Rule 23(a)(1). To meet this requirement, the class representatives need show only that it is difficult or inconvenient to join all members of the class. See Phillips v. Joint Legislative Comm., 637 F.2d 1014, 1022 (5th Cir. Unit A Feb.1981). Defendants do not challenge the numerosity of the class.
2.
The test for commonality is met “where there is at least one issue, the resolution of which will affect all or a significant number of the putative class members.” Lightbourn v. County of El Paso, 118 F.3d 421, 426 (5th Cir.1997). While the commonality hurdle is not particularly high, a plaintiff must go beyond merely describing issues at the highest level of generality.9 In Mullen v. Treasure [406]*406Chest Casino, 186 F.3d 620 (5th Cir.1999), commonality was present, because the putative class members would assert claims for negligence under the Jones Act and for operating an unseaworthy vessel. The court found that the common issues pertaining to the theories of liability-i.e., the class members' status as Jones Act seamen, the negligence of Treasure Chest, and the unseaworthiness of the Casino-were independently sufficient to establish commonality.10
In Allison v. Citgo Petrolenm Corp., 151 F.3d 402, 408 (5th Cir.1998), the court, confronting a class of roughly one thousand persons, who alleged similar causes of action as these plaintiffs (disparate treatment and impact) and sought similar remedies (injunction compensatory and punitive damages) noted, without challenge, that the class met the rule 23 requirements. The similarities between the Allison plaintiffs and the current plaintiffs strongly suggest that the district court did not abuse its discretion.
Plaintiffs allege that Star used a defective evaluation policy: the defect being both that it had a disparate impact and that it was employed with discriminatory intent.11 Although these are broad claims, they surpass the low threshold of commonality. Because there is at least one issue the resolution of which will affect all or a significant number of class members-whether the policy has a disparate impact on black employees-the commonality test is met.12
3.
Like the test for commonality, the test for typicality is not demanding. It "focuses on the similarity between the named plaintiffs' legal and remedial theories and the theories of those whom they purport to represent," Lightbourn, 118 F.3d at 426, and is satisfied when the resolution of common questions affects all [407]*407or a substantial number of class members, Shipes, 987 F.2d at 315. It is not necessary that each class member suffer the same degree of harm. Here, plaintiffs assert similar claims: They do not argue that one was trespassed against while another was the object of discrimination. The class purports to consist of similarly-situated black employees who were exposed to the same policies. That the time period of exposure may differ, or that some were less affected by the policy, would not necessarily prevent a finding of typicality. It might, however, affect other considerations, such as damage levels or predominance.
4.
Differences between named plaintiffs and class members render the named plaintiffs inadequate representatives only where those differences create conflicts between the named plaintiffs’ and the class members’ interests.13 Star challenges the district court’s adequacy determination on the basis that some of the class members have supervised other class members,14 and several of the named plaintiffs have claimed that the PMP was applied fairly to them.
Star points to Gen. Tel. Co. v. Falcon, 457 U.S. 147, 102 S.Ct. 2364, 72 L.Ed.2d 740 (1982), in which the Court decertified a class after deciding that the named plaintiff, who claimed to suffer from an intentional act of discrimination, sought to represent a class that proceeded on a disparate impact theory.15 The Court held that the individual and class claims should have been tried separately, because the “evidentiary approaches to the individual and class claims were entirely different.” Id. at 159, 102 S.Ct. 2364. Combining the two claims would not advance “the efficiency and economy of litigation which is a principal purpose of the [class action] procedure.” Id. (quoting Am. Pipe & Constr. Co. v. Utah, 414 U.S. 538, 553, 94 S.Ct. 756, 38 L.Ed.2d 713 (1974)).
Because several of the named plaintiffs assert that they always have received good marks on their PMP’s, it seems at first glance that General Telephone should apply. Chief Justice Burger’s separate opinion tempers such application, however: He notes that in General Telephone there was no allegation that those who made the hiring decisions were the same persons who made the promotion decisions. Id. at 162 n. *, 102 S.Ct. 2364 Our case differs; [408]*408the named plaintiffs’ claim that Star, at the organizational level, engaged in discriminatory practices is equivalent to the allegation described by Chief Justice Burger. Up to this point, we find no abuse of discretion.
E.
Certification under rule 23(b)(2) requires plaintiffs to show that “the party opposing the class has acted or refused to act on grounds generally applicable to the class, thereby making appropriate final injunctive relief or corresponding declaratory relief with respect to the class as a whole.” Rule 23(b)(2). This includes a requirement that claims for injunctive relief predominate over claims for monetary relief. Id. (advisory committee notes). Injunctive relief predominates where the monetary relief is “incidental”16 to the injunctive relief, but does not predominate where the monetary relief depends on the varying circumstances and merits of each individual’s case, making it less of a group remedy. Allison, 151 F.3d at 410-13.
The comparative nature of the predomination inquiry means that seemingly minor differences between or among causes of action or damages sought can produce dramatically different results. For instance, if the plaintiffs had sought only injunctive and declaratory relief, this case could have been certified under rule 23(b)(2); there would have been no money damages to predominate. It is also plain that the presence of any amount of money damages does not result in a per se finding of predomination. Finally, considering Allison and rule 23(b)(2)’s formulation, the instant claims could not have been certified under that paragraph, because compensatory and punitive damages predominate over injunctive/declaratory relief.
Before addressing the issues relevant to the rule 23(b)(3) certification, two points deserve attention. First, we address Star’s protestation that injunctive relief is not available because Star is no longer a going concern. Even though Star has been reorganized and reconstituted among new partners under a new name (“Motiva”), this fact alone does not block an injunction against practices that have a disparate impact on black employees in the current organization. To see the corporate change as a bar to enjoining a discriminatory practice would create an end-run around the statute.17
Second, contrary to the defendants’ protestations, we have allowed and even have required notice in rule 23(b)(2) class actions in which equitable monetary claims were at stake. See Johnson v. Gen. Motors Corp., 598 F.2d 432, 438 (5th Cir. 1979). Additionally, Allison recognized that providing rule 23(b)(2) class members with the procedural safeguards of notice and opt-out can permit civil rights class actions to proceed under that rule. Id. at 418. Therefore, the district court did not abuse its discretion when it granted the plaintiffs an opt-out procedure under rule 23(b).
F.
Rule 23(b)(3) permits certification of a class action otherwise meeting the requirements of rule 23(a) where
[409]*409the court finds that the questions of law or fact common to the members of the class predominate over any questions-affecting only individual members, and that the class action is superior to other methods for a fair and efficient adjudication of the controversy. The matters pertinent to the findings include: (A) the interests of the members of the class in individually controlling prosecution or defense of separate actions; (B) the extent and nature of any litigation concerning the controversy already commenced by or against members of the class; (C) concentrating the litigation of the claims in a particular forum; (D) the difficulties likely to be encountered in management of a class action.
Rule 23(b)(3). The two main inquiries are whether common issues predominate over individual issues and whether the class action is a superior adjudicatory scheme.
The predominance inquiry involves a comparison of the issues common among the class members and the issues individual to them. This analysis remains unchanged whether a class is certified under one or more sections of rule 23(b). The inquiry’s constancy serves as an important limitation on the use of bifurcation by preventing a district court from manufacturing predominance through the “nimble use” of rule 23(c)(4). Castano v. Am. Tobacco Co., 84 F.3d 734, 745 n. 21 (5th Cir.1996).
Therefore, the cause of action, as a whole, must satisfy rule 23(b)(3)’s predominance requirement. Id. Once that requirement is met, rule 23(c)(4) is available to sever the common issues for a class trial.18 To read the rule not as a housekeeping rule, but instead as allowing a court to pare issues repeatedly until predomination is achieved, would obliterate rule 23(b)(3)’s predominance requirement, resulting in automatic certification in every case in which any common issue exists, a result the drafters of the rule could not have intended.
With this limitation in mind, we apply the predominance test to the instant facts. We first consider the nature of compensatory damages, borrowing from Allison:
The very nature of these damages, compensating plaintiffs for emotional and other intangible injuries, necessarily implicates the subjective differences of each plaintiffs circumstances; they are an individual, not class-wide, remedy. The amount of compensatory damages to which any individual class member might be entitled cannot be calculated by objective standards. Furthermore, by requiring individualized proof of dis[410]*410crimination and actual injury to each class member, compensatory damages introduce new and substantial legal and factual issues.
Allison, 151 F.3d at 417. Compensatory damages, then, must be placed on the "individual" side of the equation, counseling against a finding of predominance. To do otherwise would allow a class action to "degenerate in practice into multiple lawsuits separately tried." Castano, 84 F.3d at 745 n. 19 (citing rule 23 (advisory coin-mittee notes)).
Plaintiffs, however, point to Warnell v. Ford Motor Co., 189 F.R.D. 383 (N.D.Ill. 1999), in which the court, after acknowledging that a sexual harassment claim, by nature, is highly individualized, certified the class under rule 23(b)(2) and (3). War-nell is inapposite on the issue of compensatory damages, for that court focused on the legal standards that govern sexual harassment liability. Reference to War-nell does help, however, to demonstrate the necessity of considering liability and damages issues separately during the predominance inquiry.
Plaintiffs' reliance on Warnell as a means of avoiding Allison is misplaced. Warnell does not engage Allison until it discusses certification under rule 23(b)(2), and then only to pronounce that the holding regarding whether compensatory damages are incidental to injunctive relief is dictum. See Warnel4 189 F.R.D. at 389. Moreover, War'nell `s characterization of Allison `s language has been superseded in its own circuit. In Lemon v. Int'l Union of Operating Eng'rs, 216 F.3d 577 (7th Cir.2000), the court, relying on Allison, vacated a rule 23(b)(2) class certification where the class had requested compensatory damages, reasoning that the damages were not incidental to the injunctive relief requested. Lemon, 216 F.3d at 577. By doing so, the Lemon court overruled War-nell.
We next consider whether punitive damages require an individual inquiry. First, punitive damages are not available for disparate impact claims. In Kolstad v. Am. Dental Ass'n, 527 U.S. 526, 534, 119 S.Ct. 2118, 144 L.Ed.2d 494 (1999), the Court emphasized that there must be malice or reckless indifference that is directed at the federally-protected rights of an aggrieved individual. Id. Specifically, the Court, id. at 534-35, 119 S.Ct. 2118, considered whether, for punitive damages, there must be egregious misconduct (in addition to the mere existence of discriminatory intent). In deciding that "intent determines whether remedies are open," the Court highlighted the subjectivity necessary for liability. Id. at 535-36, 119 S.Ct. 2118.
Punitive damages have not been assessed merely on a finding that the defendant engaged in a pattern or practice of discrimination. Such a finding establishes only that there has been general harm to the group and that injunctive relief is appropriate. See Price Waterhouse v. Hopkins, 490 U.S. 228, 266, 109 S.Ct. 1775, 104 L.Ed.2d 268, (1989) (O'Connor, J., concurring in the judgment). The Court's precedent supports the view that an individualized inquiry is necessary to determine liability for punitive damages in the title VII context, at least where, as here, there are a series of decisions made by various personnel.
Further support comes from this circuit's caselaw. In Patterson v. P.H.P. Healthcare Corp., 90 F.3d 927, 940 (5th Cir.1996), a title VII case, we held that compensatory and punitive damages no longer could be presumed from a mere violation of a plaintiffs rights; a degree of specificity is required to support a damage award. Our subsequent jurisprudence is worth review.
In Deffenbaugh-Williams v. Wal-Mart Stores, Inc., 156 F.3d 581 (5th Cir.1998), [411]*411we initially receded from that part of Patterson that had discussed vicarious liability. Deffenbaugh-Williams, however, was vacated for rehearing en banc and was reinstated in part by the en banc court, which, notably, did not reinstate the discussion of punitive damages. See Deffenbaugh-Williams v. Wal-Mart Stores, Inc., 182 F.3d 333 (5th Cir.1999) (en banc). Before this court decided Deffenbaugh-Williams en banc, we decided Allison, which cited Patterson for the proposition that “recovery of compensatory and punitive damages in title VII cases requires individualized and independent proof of injury to, and the means by which discrimination was inflicted upon, each class member.” Allison, 151 F.3d. at 419. Next in line was Kolstad, discussed su/pra.
Finally, it is helpful to consider Hardin v. Caterpillar, Inc., 227 F.3d 268 (5th Cir. 2000), in which this court faced the question whether a district court had erred in refusing to submit an issue of punitive damages to the jury. The court granted a new trial after determining that the punitive damages issue could not be tried alone, because the difficulty of doing so inhered in the very nature of the jury’s decisionmaking:
A jury deciding whether to award punitive damages and their amount responds to the evidence of intentional acts essential here to the underlying finding of liability. But intentional acts span a range of intensity, purpose, and foreseeability, a range that oscillates with the perceived level of emotional injury and its appropriate compensation. Many legal systems reflect this linkage of actual and punitive damages in locating caps for punitive awards. It is no answer that liability and damages here come in distinct legal capsules, because it is equally true that their expression in a verdict is a meld, a phenomenon providing essential anchors and focus to the open-ended character of punitive damages.
Id. at 272. The court remarked that it was not deciding that issues of intent, of compensatory damages, and of punitive damages are inseparable as a matter of law in all cases. See id.
The gravamen of Hardin seems to be that although there is no bright line, it is only in unlikely situations that compensatory and punitive damages will not be intertwined. The court’s description of the various factors suggests that an individual inquiry is necessary to resolve punitive damages in cases involving discrimination; Hardin offers hearty language supporting Patterson’s principles.
Additionally, language in Allison suggests that if punitive damages ever are available in a discrimination suit on a class-wide basis, without individualized proof, the instant allegations do not meet the requirements: Plaintiffs do not allege that the entire class is subjected to the same discriminatory act or same series of acts that would justify punitive damages. Rather, here as in Allison, the plaintiffs challenge broad policies and practices that were applied in a non-standard way. The named plaintiffs cannot hope to show, except by individual proof, that the policies as applied in each instance occurred with the required level of “malice or reckless indifference to the federally-protected rights of the aggrieved individual.”19
[412]*412The difference can be appreciated by considering the following: A supervisor announces to the workforce that at 5:00 that evening, each white employee will be laid off. This act is singular, and it can be assumed that the defendant acted with the same level of intent as to each white employee.20 In contrast, the requisite intent can be gleaned only from the actions of individual supervisors applying the policy. Thus, the punitive damage inquiry is placed on the “individual issue” side of the predominance equation, keeping in mind that punitive damages are available only for the disparate treatment claim.21
Plaintiffs point to two asbestos cases22 to support their claim that punitive damages can be determined on a class-wide basis. In those mass-tort cases, this circuit approved the use of a multiplier to determine the punitive damages amount. We do not revisit those holdings, which are binding circuit precedent; instead, we rely on Kolstad’s language and the statutory requirement that the defendants’ intent be directed against an aggrieved individual.23
The district court also attempted to distinguish the instant plaintiffs from the Allison plaintiffs by claiming that the former group is more homogeneous than the latter. The obstacle to this approach is that it fails to recognize that the relevant homogeneity regards the damages sought.
In Allison, the individual nature of the damage proof overwhelmed the common issues. The district court’s observation spoke to whether the grounds for liability were similar, but that the plaintiffs’ liability cases are similar does not alter the nature of the damage inquiry, save the example provided above. Were these plaintiffs identically — as opposed to similarly — situated, a court might be able to forego individual damage inquiries; but that is not the case.24
[413]*413Another concern with the district court’s approach to distinguishing the plaintiff sets is that the Allison court specifically rejected the existence of a plant-wide discriminatory practice as an “overarching issue” that would counterbalance the individual inquiry necessary to determine compensatory and punitive damages. Allison, 151 F.3d at 420. The district court departs directly from Allison on this point. Just as in Allison, the plaintiffs’ claims for compensatory and punitive damages will focus almost entirely on facts and issues specific to individuals rather than to the class as a whole.
The superiority inquiry looks to see whether the class action is truly a more efficient means of resolving the legal issues. The class action suit was designed to improve judicial economy. See id. at 410. Based on the cause of action involved here, our inquiry is constrained by the Seventh Amendment.25
Title VII forbids compensatory and punitive damages for disparate impact claims, see § 1981a(a)(l), limiting to the pattern or practice claim the Seventh Amendment right to a jury trial, see § 1981a(e).26 Once the right to a jury attaches to a claim, however, it extends to all factual issues necessary to resolve that claim. See Beacon Theatres, Inc. v. Westover, 359 U.S. 500, 510-11, 79 S.Ct. 948, 3 L.Ed.2d 988 (1959). The Seventh Amendment also requires submission to a jury of all factual issues common to legal and equitable claims, for decision on the legal claims before a final court determination of the equitable claims.27 Thus, under § 1981a, the right to a jury extends to all factual issues necessary to determine liability on the pattern or practice claim and the quantum of compensatory and punitive damages. The inseparability of the plaintiffs’ disparate treatment and disparate im[414]*414pact claims, on the one hand, from their specific remedy requests, on the other, thus presents a difficult hurdle for class certification.28
Because the same employment policies and practices are challenged under both claims, there are overlapping issues. First, an essential factual element of both claims is a finding that the challenged employment practice caused each class member to suffer an adverse employment action. To resolve either claim, the trier of fact must determine whether each class member was even in a position to be affected by the challenged employment practice (e.g., whether each member applied for an open job). Furthermore, as explained in Segar v. Smith, 738 F.2d 1249, 1268-70 (D.C.Cir.1984), significant overlap of factual issues is almost inevitable whenever disparate impact and pattern or practice claims are joined in the same action:
[T]he employer’s effort to rebut the pattern or practice claim by articulating a legitimate nondiscriminatory explanation may have the effect of putting before the court all of the elements of a traditional disparate impact case. By its explanation of an observed disparity the employer will typically pinpoint an employment practice (or practices) having a disparate impact on a protected class. And to rebut plaintiffs’ case the employer will typically be required to introduce evidence showing that the employment practice in fact caused the observed disparity. In this situation, between the plaintiffs’ prima facie showing of disparity and the defendant’s rebuttal explanation of the disparity, the essential elements of a disparate impact case will have been placed before the trier of fact.
Similarly, the business necessity defense to disparate impact claims and the legitimate nondiscriminatory reason defense to disparate treatment claims are not “so distinct and separable” from one another that they may be considered separately by multiple factfinders without violating the Seventh Amendment. Gasoline Prods. Co. v. Champlin Refining Co., 283 U.S. 494, 51 S.Ct. 513, 75 L.Ed. 1188 (1931). To rebut the plaintiffs’ claim that any one of the challenged employment practices resulted in a disparate impact, the defendants must establish that the “challenged practice is job-related for the position in question and consistent with business necessity.” 42 U.S.C. § 2000e-2(k)(l)(A)(I). A tight weave exists between these theories, making it difficult to conceive of a challenged practice that is job-related and a business necessity, and yet not a legitimate nondiscriminatory reason for an adverse employment action taken pursuant to that practice.29
In Allison, we upheld the decision not to certify a bifurcated class where the district court would have to decide the disparate impact claim before the disparate treatment claims. The district court aptly noted that to reach any equitable or incidental monetary relief, it would have to hold a [415]*415class action bench trial before trying any aspects of the pattern or practice claim to the jury, necessarily running afoul of the Seventh Amendment. Allison, 151 F.3d at 425 (citing Roscello, 726 F.2d at 221). “Nor could [the equitable issues] be advanced in a subsequent class action without being barred by res judicata and collateral estoppel.” Id. (citations omitted).30
Here, the district court attempted to avoid this problem by determining that “[t]he Seventh Amendment will not be violated in this case because all claims will be tried to a jury before any final court determination of the equitable claims is made.” While possibly avoiding the Seventh Amendment issue, this course of action creates an insurmountable superiority obstacle.
To meet the requirements of the Seventh Amendment, one jury may have to hear all the issues regarding the pattern and practice claim. This same jury would have to determine the quantum of compensatory and punitive damages. See Hardin, 227 F.3d at 272. This would require an enormous amount of time, potentially empaneling a single jury for a one-year period. This situation is not one in which the bifurcation plan certified “discrete liability” issues. To the contrary, it is a fact-intensive inquiry of a medium-sized class.
The district court offered several countervailing considerations when it stated that, in addition to there being the benefit of judicial economy, the plaintiffs would benefit from a Teamsters approach, rather than being forced to prove intentional discrimination via McDonnell Douglas.31 The court was convinced that, without certification, there would be unnecessary duplication of effort, increased litigation costs, and consumption of judicial res[416]*416ources.32 The court also felt that timid, though wronged, plaintiffs who might not sue alone would have their claims brought should their be a class option. The court twice remarks that subclasses may be employed to resolve manageability problems. Such a remark seems to underestimate the logistical demands created by the right to jury trial coupled with the individual inquiries. To repair the Seventh Amendment problem, the court created a superiority problem.33
A second superiority obstacle flows from our predominance inquiry. The predominance of individual-specific issues relating to the plaintiffs’ claims for compensatory and punitive damages in turn detracts from the superiority of the class action device in resolving these claims.34 These manageability problems are exacerbated by the facts of this case.35
Finally, the “most compelling rationale for finding superiority in a class action' — the existence of a negative value suit — is missing in this case.” See Castano, 84 F.3d at 748. The relatively substantial value of these claims and the availability of attorneys’ fees eliminate financial barriers that might deter individuals from pursuing claims. See id. Although a negative value suit is not a prerequisite to class certification, its absence is a significant detraction from the superiority of the class action device. Based on these several limitations, the district court abused its discretion when it found the class action format to be superior.
En toto, the plaintiffs attempt to avoid decertification by arguing that the common, umbrella issue regarding the existence of plant-wide, racially-discriminatory practices or policies at the Star locations justifies rule 23(b)(3) class certification. This argument, however, fails to appreciate the overwhelming number of individual-specific issues, as to both the theories of recovery and the damages sought. Moreover, it fails to provide a basis from which to distinguish Allison. The district court applied an incorrect legal standard in granting rule 23(b)(3) certification.

Defendants claim that Castaño requires that the district court detail a litigation plan. This is an overstatement. In Castaño, we criticized the district court for certifying a class in the absence of any knowledge of how an addiction-as-injury case actually would be tried. Castano, 84 F.3d at 745. Castaño did not establish a general rule; rather, it disallowed certification where the district court had confronted a claim involving an enormously complicated (and immature) mass tort with no track record of trials from which the district court could draw the information necessary to make the predominance and superiority analysis required by rule 23. See id. at 747. Castaño merely requires [417]*417district courts to appreciate the legal theories applicable in a particular case, not to recite standard management strategies for common suits.
This case is both different from and similar to Castaño. Its difference lies in the fact that employment discrimination cases are not new-fangled. Its similarity lies in the fact that the district court might have been able to describe a management plan that would resolve the superiority challenges presented in this case. It did not do so, however. This omission is a lost opportunity, not a defect.

Rule 23(f) states:
A court of appeals may in its discretion permit an appeal from an order of a district court granting or denying class action certification under this rule if application is made to it within ten days after entry of the order. An appeal does not stay proceedings in the district court unless the district judge or the court of appeals so orders.
The plaintiffs argue that Texaco’s challenge to the district court’s equitable tolling of the statute of limitations is an impermissible interlocutory appeal.
Rule 23(f) is narrowly drafted and is not intended to serve as an end-run around the final judgment rule. “[UJnder Rule 23(f), a party may appeal only the issue of class certification; no other issues may be raised.” Bertulli v. Indep. Ass’n of Cont’l Pilots, 242 F.3d 290 (5th Cir. 2001). “[A]n order is final only when it ‘ends the litigation on the merits and leaves nothing for the court to do but execute the judgment.’ ” United States v. Garner, 749 F.2d 281, 285 (5th Cir.1985) (quoting Firestone Tire & Rubber Co. v. Risjord, 449 U.S. 368, 373, 101 S.Ct. 669, 66 L.Ed.2d 571 (1981)). “The purpose behind [the final judgment rule] is to avoid piecemeal appeals, which in turn conserves ‘judicial energy’ and may help eliminate delay.” Sherri A.D. v. Kirby, 975 F.2d 193, 201 (5th Cir.1992) (citation omitted).
One of the exceptions to the final judgment rule is the collateral order doctrine, announced in Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). “The collateral order doctrine establishes that certain decisions of the district court are final in effect although they do not dispose of the litigation.” Davis v. E. Baton Rouge Parish Sch. Bd., 78 F.3d 920, 925 (5th Cir. 1996). Under this doctrine, some orders may be appealed despite the absence of final judgment if they (1) are conclusive, (2) resolve important questions that are separate from the merits, and (3) are effectively unreviewable on appeal from the final judgment in the underlying action.36 This rule does not properly apply to the circumstances of this case.
Without turning to the merits of the court’s equitable tolling decision, we note that if this issue comes up for review in a subsequent appeal, it is the plaintiffs’ burden to demonstrate that equitable tolling was appropriate.37 Additionally, equitable tolling applies only in “rare and exceptional circumstances.” Davis v. Johnson, 158 F.3d 806, 811 (5th Cir.1998). Neither a plaintiffs unfamiliarity with the legal process nor his lack of representation during the applicable filing [418]*418period merits equitable tolling. Barrow v. New Orleans S.S. Ass’n, 932 F.2d 473, 478 (5th Cir.1991).
The district court’s reference to Fed. R.CivP. 15(c)(3) is somewhat perplexing.38 Star employees were told by counsel in the Roberts action that they were included; at least one brief in the Roberts case contended that Star employees were part of the Roberts class. Star, however, never was made a defendant.
Nevertheless, the district court determined that the current action against Star can be treated, for limitations purposes, as if it is “adding” a previously-notified defendant to the “original pleading” in Roberts. Otherwise, the pleading in this case serves as the “original pleading” and cannot relate back to anything that is time-barred. It appears, then, that the district court allowed misled non-plaintiffs to file and relate back a new cause of action to a non-defendant of a previous (and at some level, separate) action.
Several of the defendants claim that the class should not have been certified as to them because they had neither an “employment relationship” nor an employment contract with the plaintiffs. In light of our decision that the class is to be decertified, it is sufficient for this appeal that at least one appellant was properly before this court.
