The AI Training Workforce: Misclassification's New Frontier

Quick answer: Behind every AI model is a workforce of people who train it — rating responses, writing prompts, labeling data, and grading answers in law, medicine, coding, and dozens of other fields. Most are hired as "independent contractors," paid hourly through a platform dashboard, assigned tasks, scored on quality, and deactivated when metrics slip. Under California's ABC test, that arrangement looks a great deal like employment — and if it is, these workers are owed overtime, expense reimbursement, break premiums, and potentially thousands in penalties per person. Our firm is actively litigating misclassification claims in this industry.

Who does this work, and how it's structured

The AI training economy runs on human judgment. Companies recruit doctors, lawyers, software engineers, PhDs, writers, and skilled generalists to teach models what a good answer looks like — the work generally described as data annotation, evaluation, or reinforcement learning from human feedback. The recruitment pitch emphasizes flexibility and expertise. The arrangement typically looks like this:

• You're onboarded as a 1099 contractor, often through a platform or staffing intermediary


• You're paid an hourly rate, tracked by the platform's own timer or logging tool


• Tasks are assigned through a queue or dashboard, with detailed instructions and rubrics you must follow


• Your output is graded, and your quality score determines whether you keep getting work


• There are deadlines, minimum-hour expectations, and required trainings


• You can be deactivated at any time, by a person or an algorithm, without explanation


• You supply your own computer, internet, and workspace, unreimbursed

Strip away the novelty of the industry, and this is a familiar picture: hourly workers, supervised through software, doing the company's core work.

Why the ABC test is a problem for this model

California presumes a worker is an employee unless the hiring company proves all three prongs of the ABC test (Labor Code § 2775). Prong B asks whether the work is outside the usual course of the company's business. For a company whose product is training data, model evaluation, or "human expertise for AI," the people generating that data and evaluation aren't peripheral to the business — they are the business. That is close to the definition of an employee under prong B, and the company bears the burden of proving otherwise.

Prong A doesn't rescue it. "Set your own hours" flexibility coexists with rubrics, quality scores, throughput expectations, mandatory training, and deactivation — which is control in software form. And prong C asks whether the worker runs an independently established business of the same kind; a physician grading medical answers between shifts is not operating an AI-evaluation company.

California does exempt certain "professional services" from the ABC test, but the exemption requires — among other things — that the worker maintain a business location separate from the hiring company, negotiate their own rates, and set their own hours outside project deadlines. Platform-set hourly rates and dashboard-assigned tasks are hard to square with that.

What misclassified AI workers may be owed

If the label falls, so does everything it took:

• Overtime for weeks over 40 hours or days over 8 — common during model-release crunches


• Meal and rest break premiums for shifts worked straight through the timer


• Reimbursement for the computer, internet, software, and home-office costs you were required to provide (Labor Code § 2802)


• Wage statement and waiting time penalties


• Willful misclassification penalties of $5,000–$25,000 per violation (Labor Code § 226.8), enforceable through PAGA across the entire workforce

Because platforms classify their whole workforce the same way, these are natural class and PAGA cases — one worker's claim tests a policy applied to thousands.

Frequently asked questions

I'm in another state. Does any of this apply to me? California law reaches California workers and, in some circumstances, work directed from California. Federal law and other states apply their own tests, several of which lean toward employee status on these facts. It's worth asking regardless of where you sit.

I signed an agreement saying I'm an independent contractor and I'm not entitled to overtime. You can't waive employee status by contract. Those agreements often help the worker's case by documenting how much control the company reserved.

I liked the flexibility. Wouldn't reclassification ruin that? Employees can have flexible schedules; plenty do. Reclassification changes who pays for the equipment, the taxes, and the overtime — not whether you can work at 11 p.m.

Will I be deactivated for raising this? Retaliating against a worker for asserting employee status is illegal. And in class and PAGA cases, the coworkers a case protects are never identified — only the representative plaintiff is named.

I was deactivated already. Is it too late? Claims reach back three to four years, and PAGA claims one year from your last violation. Former workers frequently make the strongest representatives.
