Independent-Contractor Misclassification and the ABC Test

A practitioner’s synthesis of the controlling authority on worker classification in California — the Dynamex ABC test and its codification in AB 5, the surviving Borello standard for exempt work, retroactivity after Vazquez, the Proposition 22 carve-out upheld in Castellanos, and the penalties for willful misclassification.

In brief. For most wage-and-hour purposes, California presumes a worker is an employee unless the hiring entity proves all three prongs of the ABC test: (A) the worker is free from the hiring entity’s control in performing the work; (B) the work is outside the usual course of the hiring entity’s business; and (C) the worker is customarily engaged in an independently established trade of the same nature. (Dynamex Operations West, Inc. v. Superior Court (2018) 4 Cal.5th 903.) AB 5 codified and extended the test (Lab. Code, § 2775 et seq.), the ABC test applies retroactively to pre-Dynamex conduct (Vazquez v. Jan-Pro Franchising Internat., Inc. (2021) 10 Cal.5th 944), the older multifactor Borello standard still governs exempt occupations (S.G. Borello & Sons, Inc. v. Dept. of Industrial Relations (1989) 48 Cal.3d 341), and app-based drivers remain contractors under Proposition 22, upheld in Castellanos v. State of California (2024) 16 Cal.5th 588. This guide collects the governing authority and the points that decide these cases.

1. Why classification decides everything

Classification is the gateway to nearly every protection in the Labor Code. An employee is owed minimum wage and overtime, meal and rest periods, expense reimbursement, wage statements, and unemployment and workers’ compensation coverage; an independent contractor is owed none of these. Misclassification therefore is not a discrete claim so much as the foundation that makes — or unmakes — a stack of wage-and-hour claims, and it is frequently the threshold issue in wrongful-termination and retaliation cases brought by workers the employer labeled “contractors.” Because the consequences are so large, the governing test, its statutory codification, and its exceptions repay careful study.

2. The ABC test (Dynamex)

In Dynamex Operations West, Inc. v. Superior Court (2018) 4 Cal.5th 903, the Court adopted the “ABC test” for determining employee status under the IWC wage orders, replacing the multifactor standard for those claims. Under the test, a worker is presumed to be an employee, and the hiring entity bears the burden of establishing each of three conditions to treat the worker as an independent contractor:

(A) that the worker is free from the control and direction of the hirer in connection with the performance of the work, both under the contract and in fact; (B) that the worker performs work that is outside the usual course of the hiring entity’s business; and (C) that the worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed. (Dynamex, supra, 4 Cal.5th at p. 957.)

Because the hirer must prove all three, the failure of any single prong makes the worker an employee. In practice, prong B is the most consequential: a worker who performs the very service the business sells — a seamstress for a clothing manufacturer, a driver for a delivery company — will almost always be inside the usual course of business and therefore an employee, regardless of contractual labels or scheduling flexibility.

3. AB 5 codified and extended the test (Lab. Code § 2775)

The Legislature codified Dynamex in Assembly Bill 5 (2019), now Labor Code section 2775 et seq., and extended the ABC test beyond the wage orders to the Labor Code and the Unemployment Insurance Code generally. AB 5 and its successor AB 2257 (2020) also created an elaborate set of exemptions — for specified professions and bona fide business-to-business contracting, among others — for which the ABC test does not apply and the older Borello standard governs instead. The exemptions are intricate and condition-laden; counsel must check whether a given occupation or relationship qualifies, because the exemption determines which legal test applies, and the test usually determines the outcome.

4. When Borello still governs

The ABC test did not abolish the older standard. Under S.G. Borello & Sons, Inc. v. Dept. of Industrial Relations (1989) 48 Cal.3d 341, classification turns on the hirer’s right to control the manner and means of the work, supplemented by secondary factors — whether the worker is engaged in a distinct occupation, who supplies the tools and place of work, the method of payment, the length of the relationship, and whether the work is part of the hirer’s regular business, among others. (Borello, supra, 48 Cal.3d at p. 350.) Borello remains the test for the statutory exemptions under AB 5/AB 2257 and for certain claims outside the ABC test’s reach. The two tests can yield different results on the same facts, so the first question in any classification dispute is which test applies.

5. Retroactivity (Vazquez)

In Vazquez v. Jan-Pro Franchising Internat., Inc. (2021) 10 Cal.5th 944, answering a question certified by the Ninth Circuit, the Court held that Dynamex applies retroactively to all cases not yet final when it was decided. (Vazquez, supra, 10 Cal.5th at p. 948.) The Court reasoned that Dynamex addressed a previously unsettled question and that ordinary judicial decisions operate retroactively. The result is significant exposure for hiring entities that relied on the pre-Dynamex regime for wage-order claims arising before April 2018, within the limitations period.

6. The Proposition 22 carve-out (Castellanos)

The most prominent statutory exception is Proposition 22 (2020), which classifies app-based rideshare and delivery drivers as independent contractors (subject to specified pay and benefit guarantees) notwithstanding AB 5. Its validity was challenged on the ground that it impermissibly limited the Legislature’s constitutional authority over workers’ compensation. In Castellanos v. State of California (2024) 16 Cal.5th 588, the Court upheld Proposition 22, holding that the Legislature’s plenary power over workers’ compensation is not exclusive and does not preclude the electorate from legislating by initiative. (Castellanos, supra, 16 Cal.5th at p. 609.) The upshot is a stable, sector-specific carve-out: app-based drivers within the measure’s scope remain contractors, while the ABC test continues to govern most other workers. (For the contrasting application of prong B to a delivery platform before Proposition 22, see People v. Uber Technologies, Inc. (2020) 56 Cal.App.5th 266, 292 [affirming a preliminary injunction].)

7. Remedies and penalties for misclassification

A reclassified worker may recover the full range of wage-and-hour relief that flows from employee status: unpaid minimum and overtime wages (Lab. Code, §§ 1194, 1197, 510), meal and rest premiums (§ 226.7), unreimbursed business expenses (§ 2802), wage-statement penalties (§ 226), and waiting-time penalties (§ 203), often aggregated through a class action or PAGA. In addition, Labor Code section 226.8 imposes substantial civil penalties for the willful misclassification of an individual as an independent contractor, with enhanced penalties for a pattern or practice. Misclassification claims also pair naturally with retaliation and wrongful-termination theories where a worker was discharged for asserting employee rights or challenging the “contractor” label.

8. Practice pointers

  • Decide which test applies first. The threshold question is ABC (Dynamex/AB 5) versus Borello; check the AB 5/AB 2257 exemptions before anything else, because the test usually dictates the result.
  • Attack on prong B. Under the ABC test, focus on whether the worker performs the hiring entity’s core service; prong B alone is frequently dispositive and resists individualized defenses.
  • Remember the burden is the hirer’s. The worker is presumed an employee; the hiring entity must prove all three prongs — frame motions and discovery accordingly.
  • Leverage retroactivity. After Vazquez, pre-2018 wage-order conduct is fair game within the limitations period.
  • Screen for the Prop 22 sector. App-based driving is carved out after Castellanos; confirm whether the worker and platform fall within the measure’s defined scope before pleading misclassification.
  • Plead § 226.8 and the derivative wage claims. Willful-misclassification penalties and the stacked wage-and-hour claims are the real exposure; build them into the demand and the PAGA notice.

Frequently asked questions

What is the ABC test in California?

The ABC test is how California decides whether a worker is an employee or an independent contractor. The worker is presumed an employee unless the hiring business proves all three: (A) the worker is free from its control, (B) the work is outside the company’s usual business, and (C) the worker runs an independent business of the same kind (Dynamex Operations West v. Superior Court (2018)).

What is prong B of the ABC test?

Prong B asks whether the work the person does is outside the usual course of the hiring company’s business. It is the hardest prong for companies to meet, because a worker who performs the company’s core service — such as a driver for a delivery company — fails it and is therefore an employee.

When does the ABC test apply instead of the Borello test?

The ABC test, codified by AB 5 (Labor Code section 2775), governs most wage, Labor Code, and unemployment-insurance claims. The older, multi-factor Borello test still applies to specific statutory exemptions and to some claims AB 5 does not cover (S.G. Borello & Sons v. Department of Industrial Relations (1989)).

Are Uber and Lyft drivers employees in California?

It depends on the law applied. California sued to enforce the ABC test against Uber and Lyft (People v. Uber Technologies (2020)), but Proposition 22 (2020) created a separate category treating many app-based drivers as independent contractors with limited benefits — an area still being litigated.

What can I recover if I was misclassified as an independent contractor?

A misclassified worker can recover unpaid minimum wage and overtime, meal- and rest-break premiums, unreimbursed business expenses, and penalties, plus attorney’s fees — remedies independent contractors do not receive. Misclassification claims are often brought as class or PAGA actions.
