Worker Status Disputes in the United Kingdom

What is this right?
The UK has three legal employment statuses, and they unlock different rights:
- Employee — full set: unfair dismissal protection (after 2 years), redundancy pay, maternity/paternity leave, statutory sick pay, written contract.
- Worker — narrower but still substantial: National Minimum Wage, paid holiday (5.6 weeks), protection from unauthorised deductions, anti-discrimination, whistleblowing.
- Self-employed — almost none of the above, unless the contract is a sham.
The Supreme Court has been clear in three landmark cases that the label your engager puts on the relationship is not the final word:
- Uber BV v Aslam [2021] UKSC 5 — Uber drivers were workers despite contracts labelling them self-employed contractors.
- Autoclenz Ltd v Belcher [2011] UKSC 41 — courts may disregard contract terms that don't reflect the actual relationship ("sham" provisions).
- Pimlico Plumbers Ltd v Smith [2018] UKSC 29 — a meaningful right of substitution defeats worker status; a fettered, theoretical one doesn't.
If you're labelled self-employed but the engager controls when, where, and how you work — and you personally do the job — you're probably a worker, and you have rights.
When does it apply?
- You work for a platform (Uber, Deliveroo, Amazon Flex, Bolt, Just Eat) under a self-employed label.
- You're a contractor labelled self-employed but treated like a worker — fixed hours, branded uniform, no genuine right to send a substitute.
- You're an agency worker or zero-hours worker being denied National Minimum Wage, holiday pay, or pension auto-enrolment.
- You want to bring a discrimination claim under the Equality Act 2010 — note s.83 has a wider "employment" definition than s.230 ERA, so even some self-employed people may have protection.
What to Do If You've Been Wrongly Labelled Self-Employed
- Document everything — your shift logs, screenshots of the platform app, evidence the engager controls your work, evidence you can't realistically send a substitute, evidence the engager integrates you into its business.
- Send a worker-status determination letter to the engager invoking Uber, Autoclenz, and Pimlico Plumbers. Demand acknowledgment within 21 days.
- If you're denied a specific worker right (NMW, holiday pay), the time limit is 3 months less 1 day from each denial — file Acas Early Conciliation within that window (12-week conciliation period from 1 December 2025, SI 2025/1153).
- HMRC's Employment Status Indicator (ESI) tool is a useful starting point but is not binding on an Employment Tribunal. Don't rely on it alone.
- Free help: Work Rights Centre (workrightscentre.org), App Drivers and Couriers Union (ADCU), Independent Workers' Union of Great Britain (IWGB).
What should you NOT do?
- Don't assume your contract is the final word. A clause saying "you are self-employed and not a worker" can be disregarded under Autoclenz if it doesn't reflect the actual relationship.
- Don't wait. The 3-months-less-1-day clock runs from each instance of denied right, not from when you first realised you might be a worker.
- Don't worry about your tax status. HMRC's view of whether you're "self-employed for tax" doesn't bind an Employment Tribunal on worker status for employment-rights purposes — they're separate tests.
