Two companies, one job: staffing agencies and joint employment
The badge says one company, the paycheck says another, and when wages go missing each points at the other. California ended that game by statute — the client business often owes you the money too.
Staffing arrangements are designed to divide a job’s legal identity: the agency hires and pays; the client directs and benefits; and when something goes wrong — unpaid overtime, a missing final check, a harassment complaint routed to a voicemail — the structure itself becomes the defense. California has spent two decades closing that maneuver. If you work through an agency, at a client, on a contract, or under a “vendor,” this primer is about who actually owes you what.
1 · Employer is a function, not a name
California’s wage orders define employment broadly — including to suffer or permit work, and to exercise control over wages, hours, or working conditions — and the Supreme Court confirmed in Martinez v. Combs that more than one entity can meet the definition for the same job at the same time.1 The client that sets your schedule, directs your work, and benefits from it does not escape the definition by outsourcing the payroll file.
2 · The statute that skips the argument
For the classic staffing arrangement, the Legislature removed the fight entirely: under Labor Code section 2810.3, a client business that obtains workers from a labor contractor shares liability automatically for the payment of wages and for workers’ compensation coverage.2 Not liability after a control analysis — shared liability by statute, with anti-waiver and anti-retaliation provisions built in. The practical translation: for wage claims, the deep pocket at the top of the arrangement is generally in the case from day one.
3 · Beyond wages
Joint responsibility does not stop at the paycheck. FEHA reaches harassment and discrimination against contract and agency workers at the client’s site — the client cannot enjoy the work and disclaim the workplace. Retaliation protections follow the same logic: the client that ends an assignment because the worker complained has taken an adverse action, whatever the agency’s paperwork says about who “employs” whom. And the ABC test looks through labels here as everywhere — some “vendor” arrangements are simply employment with an intermediary’s logo.
4 · Why the structure exists, and what it costs workers
Layered employment diffuses accountability by design: the agency knows the hours but not the conditions; the client knows the conditions but “doesn’t handle” pay; complaints fall into the seam. It also produces the recurring harms we see — the assignment ended without explanation the week after a complaint; the overtime split across two entities’ records so neither shows it; the final check that each company insists the other owes. The seam is where the violations live. It is also, litigated properly, where the leverage lives: two defendants, joint exposure, and records that must reconcile.
5 · What to do, practically
Keep everything with a name on it: the agency contract, the client’s schedules and instructions, badges, both sets of paystubs if they exist. Note who actually directs your day — names, not entities. When something goes wrong, complain in writing to both companies; the seam closes when both are on notice. And when you write to us, bring the whole paper trail from both sides. Cases like yours are decided by which names end up in the caption — and our first job is making sure all of them do.
