California Court of Appeal Says Employee’s Arbitration Loss Barred His PAGA Claim in Sorokunov v. NetApp
Estimated Reading Time: 8 minutes
California employers continue to look for reliable guidance on what happens when an employee’s individual Labor Code claims go to arbitration first, while a representative Labor Code Private Attorneys General Act (PAGA) claim remains pending in court. In Sorokunov v. NetApp, Inc., California’s First District Court of Appeal delivered one answer. After the employee lost his individual Labor Code claims in arbitration, and the trial court confirmed that award, the court held he could no longer continue with a PAGA claim based on the same alleged violations. In the court’s view, the arbitration result established that he was no longer an “aggrieved employee” with standing to pursue PAGA penalties.
The decision is instructive for several reasons. It addresses the enforceability of an arbitration provision contained in a compensation plan, the meaning of Labor Code section 2751’s requirement that commission agreements state how commissions will be computed and paid, the employee’s theories under Labor Code sections 221 and 223, and the increasingly important question of how issue preclusion can affect PAGA standing after an employee’s individual claims have already been decided.
A commission dispute turned into a broader wage-and-hour fight
Alexander Sorokunov worked for NetApp from 2016 until June 2019. According to the opinion, his compensation included both an annual salary and commissions. Those commissions were governed by an individual goal sheet and NetApp’s fiscal year 2019 compensation plan. The plan tied commissions to revenue goals, but it also included a “windfall” provision allowing NetApp to limit commission payments in certain circumstances, including where goal attainment exceeded 200 percent.
That “windfall” provision became the center of the dispute. The opinion explains that Sorokunov and roughly 300 other sales-related employees earned commissions tied to sales above 200 percent of their assigned goals in fiscal year 2019. NetApp then informed those employees that it was invoking the windfall provision and that further commissions above 200 percent of goal attainment would not be paid. As a result, Sorokunov’s last check for that fiscal year was more than $31,000 lower than it would have been without the windfall limitation. He resigned the following month and later submitted a PAGA notice to the Labor and Workforce Development Agency (LWDA) and to NetApp.
In his lawsuit, Sorokunov alleged that NetApp’s compensation practices violated Labor Code section 2751, which requires commission agreements to be in writing and to state the method by which commissions are computed and paid. He also alleged violations of Labor Code sections 221 and 223, arguing in substance that NetApp had unlawfully taken back or underpaid commissions. He paired those claims with theories under the unfair competition law, breach of contract, waiting time penalties, and PAGA.
The order of events shaped the result
The case unfolded in a sequence that ultimately became decisive. In December 2020, the trial court compelled arbitration of Sorokunov’s individual non-PAGA claims, but it did not stay the PAGA portion of the case. While arbitration was pending, Sorokunov moved for summary adjudication on part of his PAGA theory, arguing that the compensation plan violated Labor Code section 2751. The trial court denied that motion. Then, in July 2024, the arbitrator ruled in NetApp’s favor on every individual claim. The trial court later confirmed the arbitration award and granted NetApp judgment on the pleadings as to the PAGA claim, concluding that Sorokunov lacked standing to continue as an “aggrieved employee” under PAGA.
On appeal, Sorokunov challenged nearly every major ruling. He argued the arbitration agreement was illusory and unenforceable, the trial court should have granted summary adjudication on the section 2751 issue, the arbitration award should not have been confirmed, and the courts should not have given preclusive effect to the arbitration findings when dismissing the PAGA cause of action. The Court of Appeal rejected all of those arguments and affirmed the judgment.
NetApp’s arbitration clause survived challenge
Sorokunov argued that NetApp’s promise to arbitrate was illusory because provisions in the compensation plan allowed the company to revise, suspend, or terminate the plan. In his view, those provisions gave NetApp too much unilateral power, including the power to affect known but unfiled claims.
The Court of Appeal disagreed. Reading the plan as a whole, the court concluded that NetApp’s ability to modify the plan existed only to the extent permitted by applicable law. Under California law, the implied covenant of good faith and fair dealing prevented NetApp from applying modifications to known but unfiled claims. Because of that limitation, the court held the arbitration agreement was not illusory and was enforceable.
For employers, that part of the opinion is a reminder that amendment language in arbitration provisions will be examined closely. At the same time, language tying modifications to applicable law may help preserve enforceability where California law supplies implied limits on how that discretion may be exercised.
The court rejected a rigid reading of Labor Code section 2751
Sorokunov’s central argument was that Labor Code section 2751 requires more than a written explanation of how commissions are calculated and paid. He argued the statute required a purely mathematical method, one that would not permit an employer to retain discretion through a provision such as the windfall clause.
The court rejected that reading. It explained that section 2751 was enacted in part to address the risk that commission arrangements would be promised orally or described so opaquely that employees could not enforce them. For that reason, the statute requires a written contract explaining the commission structure. The court concluded that NetApp’s plan satisfied that requirement because it set out the method by which commissions were computed and paid and also explained the circumstances under which the initial calculation might be modified. In the court’s view, section 2751 requires disclosure of the method, not a compensation system stripped of every discretionary feature.
That holding should not be read too broadly. The opinion turned on the court’s conclusion that the compensation structure, including the possibility of a windfall limitation, was actually disclosed in writing. This decision is better understood as a case about written notice and contractual structure than as a blanket endorsement of vague or heavily one-sided commission plans.
Why the “secret reduction” theory failed
NetApp also defeated the argument that the windfall provision operated as a secret reduction in pay. Sorokunov’s theory was that the goal sheets appeared to promise one level of commissions while the compensation plan reserved the power to pay less, effectively allowing NetApp to undercut those promises after the fact. The arbitrator and the Court of Appeal rejected that characterization because the plan expressly disclosed the possibility of a windfall limitation, specifically identified attainment above 200 percent of goal as an example, and authorized a reduced commission payment in that circumstance. The arbitrator also noted that Sorokunov conceded he had read the provision. On that record, the court concluded the company had not “secretly” paid less than promised within the meaning of Labor Code section 223.
The same reasoning also helped defeat the section 221 theory. The arbitrator concluded that NetApp had not clawed back wages it had already paid. Instead, the dispute concerned what amount, under the plan’s terms, had ultimately been earned and payable once the contractual contingencies played out. The Court of Appeal noted California authority recognizing that compensation arrangements may lawfully make final amounts contingent on later events, even where employees have already performed services and even where advances have previously been paid. Against that backdrop, the court found no basis to overturn the arbitrator’s rejection of the employee’s sections 221 and 223 arguments.
Why the arbitration loss also ended the PAGA claim
The most significant part of the opinion for many employers came at the end. After NetApp prevailed in arbitration on Sorokunov’s individual Labor Code theories, the courts had to decide whether he could still continue with a PAGA claim based on those same alleged violations. The Court of Appeal said no. Once the arbitration award was confirmed, the court treated the underlying issues as conclusively resolved against him, which meant he was no longer an “aggrieved employee” with standing to pursue PAGA penalties on those same theories.
That conclusion rested on issue preclusion rather than claim preclusion, and the distinction is important. Claim preclusion asks whether the same claim is being litigated again. Issue preclusion is narrower. It asks whether a particular issue was already actually litigated and necessarily decided in an earlier proceeding. Here, the court focused on the narrower question: had Sorokunov already litigated, and lost, the issue of whether NetApp committed the Labor Code violations on which his PAGA standing depended? In the court’s view, he had.
That reasoning explains why the opinion aligned itself with Rocha, Adolph, and Rodriguez. As described by the court, Rocha held that an arbitrator’s ruling in favor of the employer on the employees’ individual Labor Code claims precluded those same employees from alleging PAGA standing based on the same purported violations. Adolph cited Rocha for the proposition that if an arbitrator determines the employee is not an aggrieved employee, and that determination is confirmed and reduced to judgment, the employee can no longer prosecute non-individual PAGA claims for lack of standing. Rodriguez was especially important because it involved the same basic procedural sequence seen here and held that an arbitrator’s prior adjudication of Labor Code violations in the employer’s favor precluded the plaintiff from continuing a PAGA claim based on those same alleged violations.
The court declined to follow Gavriiloglou, which had reasoned that an employee acts in a different capacity in arbitration than in a PAGA action. In arbitration, the employee seeks individual relief. In a PAGA case, the employee acts as a proxy for the state in seeking civil penalties. That distinction led the Fourth District court of Appeal in Gavriiloglou to conclude that the earlier loss did not preclude the later PAGA standing argument. The Sorokunov court, however, followed the Second District Court of Appeal in Rodriguez, which treated that analysis as mixing up claim preclusion with issue preclusion. From that perspective, the question was not whether the employee occupied precisely the same legal role in both proceedings. The question was whether the same underlying issue had already been decided. According to the court, it had.
The opinion also addressed the later Prime Healthcare decision, which had reaffirmed Gavriiloglou. There, the court emphasized that the arbitrator had not actually been asked to decide whether the employee was an aggrieved employee under PAGA and had not made an express finding on that gateway question. Sorokunov came out differently because the arbitrator had already determined, both legally and factually, that Sorokunov had not suffered the Labor Code violations on which his PAGA standing depended. Once those findings were confirmed, the Court of Appeal saw no room for him to continue as a PAGA plaintiff on the same theories.
For practitioners, this part of the opinion is especially helpful because it shows how much may turn on the overlap between what was decided in arbitration and what later serves as the basis for PAGA standing. For employers, the practical takeaway is simpler. When an employee’s individual Labor Code theories are fully litigated first and resolved in the employer’s favor, that result may do more than end the individual case. It may also eliminate the employee’s ability to continue pursuing PAGA penalties based on the same alleged violations.
Practical takeaways for employers
Several lessons emerge from the decision. Commission plans should be drafted with precision and should explain not only the basic formula for earning commissions, but also any review mechanisms, contingencies, caps, windfall provisions, or other limitations that may affect final payment. The clearer those features are in writing, the stronger the employer’s position will be if a later dispute turns on whether employees knew how the system operated.
Employers should also review arbitration language carefully, especially where arbitration provisions appear inside broader compensation or incentive documents. Modification clauses that appear too broad can create enforceability problems, while language tied to applicable law may help avoid the conclusion that the promise to arbitrate is illusory.
Finally, employers defending PAGA claims should pay close attention to the relationship between the employee’s individual claims and the representative claims left in court. Sorokunov does not mean every arbitration victory automatically defeats every PAGA action. The result depended on the overlap between the issues decided in arbitration and the issues on which PAGA standing later depended. But where that overlap is substantial, the employer’s arbitration win may carry consequences beyond the individual award.
