Fourteen former sales leaders (“Sales Leaders”) of defendant Cornerstone America (“Cornerstone”) filed suit for unpaid overtime wages under the Fair Labor Standards Act (“FLSA”). The federal district court granted summary judgment in favor of the Sales Leaders on the threshold issue of whether the Sales Leaders were employees or independent contractors under the FLSA. Cornerstone now appeals this ruling. The Sales Leaders cross-appeal, alleging that the district court erred in dismissing the claims of one of their members, Chris Fox (“Fox”), on the grounds of judicial estoppel. For the following reasons, we affirm in part and vacate in part.
*342 I
Cornerstone is the sales and marketing division of defendant Mid-West National Life Insurance Company of Tennessee (“Mid-West”), a corporation that issues and sells health insurance policies. Cornerstone uses a pyramid system of approximately 1,200 sales agents, each of whom agrees to work as an independent contractor on a commission basis. Some of these agents are subsequently promoted to the position of “sales leader,” a management-level position in the Cornerstone hierarchy.
By contract, sales leaders agree to remain as independent contractors when they are elevated from the position of sales agent by Cornerstone. However, their opportunity to engage in personal sales diminishes, and they become primarily responsible for recruiting, training, and managing a team of subordinate sales agents. As the leaders progress in their careers, their primary income derives from overwrite commissions on their subordinates’ sales. Despite this economic dependency, there is no formal relationship between the sales leaders and their team members. Each subordinate agent contracts directly with Cornerstone, and Cornerstone alone controls the hiring, firing, assignment, and promotion of the agents in each leader’s team. Cornerstone also unilaterally determines the sales leaders’ territories, and prevents the sales leaders from selling other insurance products or operating other businesses. Finally, Cornerstone controls the distribution of sales leads — the “lifeblood” of the business model — and prohibits sales leaders from purchasing leads from outside sources.
Despite this fairly rigid structure, sales leaders possess a great deal of flexibility with regard to their hours and day-to-day affairs. They receive no employment benefits, and Cornerstone withholds no wages for tax purposes. According to Cornerstone, corporate oversight is minimal, and the sales leaders’ attendance at Cornerstone meetings and training sessions is generally considered optional.
The plaintiff-Sales Leaders in this case are all former sales leaders of Cornerstone — four were district sales leaders, nine were regional sales leaders, and one was an area sales leader. They filed suit against Cornerstone and its parent companies in federal district court, alleging that they were entitled to unpaid overtime wages as employees under the FLSA. Because the FLSA applies to employees but not to independent contractors, the district court initially sought to determine the employment status of the Sales Leaders. After both sides submitted summary judgment motions, the court ruled in favor of employee status for all of the Sales Leaders (except Chris Fox), allowing them to proceed with their FLSA claims. As to Fox alone, the district court concluded that judicial estoppel barred him from asserting employee status because he had previously claimed to be an independent contractor in an unrelated lawsuit.
After the district court issued its summary judgment order, Cornerstone sought permission to file an interlocutory appeal on the FLSA issue. See 28 U.S.C. § 1292(b) (permitting interlocutory appeal of “controlling question[s] of law as to which there is substantial ground for difference of opinion”). The district court granted permission to appeal and certified the following question for our review: “Whether, under the undisputed facts, Plaintiffs are employees of Defendants or independent contractors under the FLSA.” After Cornerstone petitioned this Court for permission to appeal on the certified question, the Sales Leaders petitioned for permission to cross-appeal solely on the *343 estoppel ruling against Fox. We granted both petitions. 1

Cornerstone contends that the district court erred in concluding that the Sales Leaders were employees under the FLSA. We review
de novo
a district court’s legal conclusion as to employment status in a grant of summary judgment.
Carrell v. Sunland Constr., Inc.,
The definition of employee under the FLSA is particularly broad.
See Nationwide Mut. Ins. Co. v. Darden,
A
Under our economic-realities approach, “[c]ontrol is only significant when it shows an individual exerts such a control over a meaningful part of the business that she stands as a separate economic entity.”
Mr. W Fireworks,
After a review of the record, we are convinced that Cornerstone controlled the “meaningful” economic aspects of the business.
See Mr. W Fireworks,
Because Cornerstone controlled the meaningful aspects of the business model such that the Sales Leaders could not plausibly be considered “separate economic entities],”
see Mr. W Fireworks,
B.
In applying the relative-investment factor, we compare each worker’s
individual
investment to that of the alleged employer.
See Herman,
C.
We next consider whether the worker or the alleged employer controlled the “major determinants of the amount of profit which the [worker] could make.”
See Usery v. Pilgrim Equip. Co., Inc.,
The major determinants of the Sales Leaders’ profit or loss were controlled almost exclusively by Cornerstone. Cornerstone controlled the hiring, firing, and assignment of subordinate agents, and thus effectively regulated overwrite commissions — the Sales Leaders’ primary source of income. Cornerstone controlled the distribution of sales leads, and restricted the Sales Leaders from selling competing products. Cornerstone unilaterally defined the Sales Leaders’ territories, and Cornerstone could (and did) assign competing sales leaders within these territories. Finally, Cornerstone prevented the Sales Leaders from owning and operating other businesses.
Our decision in
Hickey v. Arkla Industries, Inc.
provides an instructive comparison.
D.
We also consider whether the worker exhibits the type of skill and initiative typically indicative of independent-contractor status.
See Pilgrim Equip.,
Certainly, the Sales Leaders required a general set of skills to effectively manage their offices and teams. However, these are not specialized skills; they are abilities common to
all
effective managers.
See Pilgrim Equip.,
E.
Finally, we consider the permanency of the working relationship.
Mr. W Fireworks,
In this case, almost all of the Sales Leaders worked exclusively for Cornerstone for several years. Cornerstone’s corporate representative acknowledged that sales leaders generally remained in their positions for “a significant period of time.” Furthermore, unlike the salesman in
Hickey,
the Sales Leaders could not easily terminate the relationship and take their “business organization” elsewhere.
See Hickey,
F.
Because our factors are non-exhaustive, Cornerstone contends that certain other factors weigh in favor of independent-contractor status. Specifically, Cornerstone notes that the Sales Leaders contractually agreed to be, and actually believed themselves to be, independent contractors. While this may be accurate, “[s]ubjective beliefs cannot transmogrify objective economic realities. A person’s subjective opinion that he is a businessman rather than an employee does not change his status.”
Mr. W Fireworks,
Cornerstone also contends that a finding of employee status will have a profound effect on the insurance industry, in which the use of independent contractors to sell policies is common. This concern is unfounded, as we deal only with the management-level sales leaders in this case, not sales agents generally.
G.
After reviewing the undisputed facts in light of our five factors, we are convinced that the district court correctly determined the Sales Leaders to be employees under the FLSA. As a matter of economic reality, the Sales Leaders were dependent upon Cornerstone to such an extent that they could not plausibly be considered “in business for [themselves].”
See Herman,
Ill
The Sales Leaders contend that the district court erred in invoking judicial estoppel to dismiss Fox’s claims on summary judgment. While a grant of summary judgment is generally reviewed
de novo,
we review the use of judicial estoppel only for abuse of discretion.
*347
Kane v. Nat. Union Fire. Ins. Co.,
Judicial estoppel is an equitable doctrine that “prevents a party from asserting a position in a legal proceeding that is contrary to a position previously taken in the same or some earlier proceeding.”
Hall v. GE Plastic Pac. PTE Ltd.,
Sales Leader Fox was previously sued for sexual harassment under the Texas Commission on Human Rights Act (“TCHRA”). See Tex. Lab.Code Ann. § 21.001 et seq. (Vernon 1996). As a defense to that action, Fox asserted in his pleadings and during his deposition that he was an independent contractor and thus outside scope of the TCHRA. The matter eventually settled before trial. In this case, the district court invoked judicial estoppel to prevent Fox from asserting his employee status under the FLSA. The court reasoned that Fox’s prior defense in the TCHRA action was clearly inconsistent with his current claim, and that Fox intended for the previous court to accept his defense.
Fox contends that the district court erred in determining that his claim of employee status under the FLSA was “clearly inconsistent” with his earlier claim of independent-contractor status under the TCHRA. We agree.
Despite the semantic inconsistency, it is legally possible to be an employee for purposes of the FLSA and an independent contractor under most other statutes.
See Nationwide Mut.,
While this conclusion may seem paradoxical, we are convinced that it is in line
*348
with the purposes of the doctrine. Judicial estoppel is designed to reduce “the risk of inconsistent court determinations.”

For the foregoing reasons, we AFFIRM the district court’s grant of summary judgment on the employee status of the plaintiffs under the FLSA. We VACATE the district court’s grant of summary judgment on the issue of judicial estoppel against Chris Fox, and REMAND for further proceedings consistent with this opinion.
Notes
. There was some debate in the briefing over whether we had jurisdiction to hear the estop-pel-issue cross-appeal. When a district court identifies a particular ''controlling question of law” from its order for interlocutory review, we have discretion to address
any issue
contained in the original order.
Yamaha Motor Corp., U.S.A. v. Calhoun,
. Although our analysis of the clearly-inconsistent requirement disposes of the current appeal, we note that the contours of our judicial-acceptance requirement are vague. In practice, we have required that the prior court
actually accept
the party’s earlier position, "either as a preliminary matter or as part of a final disposition.”
