Uber BV v Aslam UK Supreme Court judgment (19 February 2021)

On Friday 19 February 2021, the UK Supreme Court delivered a unanimous judgment in Uber BV and others v Aslam and others [2021] UKSC 5, holding that Uber drivers are "workers" within the meaning of section 230(3)(b) of the Employment Rights Act 1996 and are entitled to the national minimum wage and 28 days of paid annual leave, calculated from the time they have the Uber app switched on and are within the authorised territory and willing to accept assignments. The judgment — delivered by Lord Leggatt and joined without dissent by four further justices — is the definitive judicial ruling on gig-worker status in England and Wales and the first time the UK Supreme Court addressed whether algorithmic platform control over workers constitutes employer control in law.

The case and its history

The proceedings began in 2015 when 25 Uber drivers filed an employment tribunal claim in London arguing that, although they were not employed under a contract of employment, they met the definition of "worker" — a statutory category between employee and genuinely self-employed — entitling them to minimum wage and holiday pay. Yaseen Aslam and James Farrar were the named test claimants and were also co-founders of what became the App Drivers and Couriers Union (ADCU). At the time of the original tribunal hearing, approximately 40,000 Uber drivers were operating in the UK, around 30,000 of them in the London area.

The Central London Employment Tribunal ruled unanimously for the drivers on 28 October 2016, finding that drivers were workers rather than self-employed contractors. Uber appealed. The Employment Appeal Tribunal upheld the finding in 2017; the Court of Appeal upheld it again in 2018. Uber applied to the UK Supreme Court. The Supreme Court heard the case and on 19 February 2021 — almost six years after the original claim was filed — dismissed Uber's appeal unanimously, affirming all three lower courts.

What the judgment held

Lord Leggatt's judgment identified five factual features that together established that Uber drivers were working under contracts with Uber during the relevant time periods, making Uber the employer for the purposes of worker-protection legislation. The five features were: that Uber sets the fares charged to passengers and drivers cannot influence those fares; that Uber imposes the contract terms on which drivers provide services, and drivers have no ability to negotiate them; that Uber constrains ride acceptance (drivers who decline too many trips are penalised or logged off); that Uber controls service delivery through its star-rating system and can remove drivers who fall below the threshold; and that Uber restricts driver-passenger communication to the period strictly necessary for the ride, preventing any relationship that might lead passengers to use drivers outside the Uber platform.

The judgment's purposive reasoning was as significant as its conclusion: Lord Leggatt held that courts must interpret employment status legislation to give effect to its protective purpose and must not allow that purpose to be defeated by contractual drafting. Uber had argued that its contracts with drivers characterised them as self-employed and that courts should take that characterisation at face value; the Supreme Court rejected this approach entirely, holding that what matters is the economic and organisational reality of the work relationship, not what the platform calls it. The court left open whether drivers were also "employees" — a stronger status carrying further protections including unfair dismissal rights — but indicated that the indicia of employment were substantially satisfied.

The practical consequence of the working-time definition — that worker rights run from app-switch-on within the authorised territory, not only from the moment a ride is accepted — was significant: it meant Uber's obligation to pay the national minimum wage applied to all the time drivers were on the app and available, not merely the time they spent carrying passengers.

Reactions and aftermath

Yaseen Aslam told CNN Business on the day of the ruling that the compensation he stood to gain was "small" compared to the effort the litigation had required, but that "someone had to do it." Worker Info Exchange, which Farrar had incorporated as a vehicle for operationalising data-subject access rights for platform workers alongside the worker-status litigation, framed the ruling as establishing that algorithmic managerial control and contractual control are legally equivalent — a reading that directly shaped WIE's subsequent data-rights litigation strategy in the Amsterdam courts.

Within weeks of the ruling, Uber announced a series of UK-wide changes: paying drivers the national living wage for time on the app, introducing automatic holiday-pay accrual, and enrolling UK drivers into an auto-enrolled pension scheme. These changes applied to approximately 70,000 UK Uber drivers at the time of implementation and represented the largest single statutory-worker benefit extension in the UK gig economy to that date.

Significance

The 19 February 2021 ruling is the corpus's definitional gig-worker judicial event and the moment at which algorithmic employment control was authoritatively determined to constitute employer control in the UK's highest court. Its precedential significance runs in two directions. Within the UK, the ruling accelerated equivalent worker-status claims across the platform economy — taxi operators, food-delivery platforms, and logistics apps faced similar claims after the Supreme Court's framework was applied to comparable factual patterns. Internationally, the Harvard Law Review characterised the ruling as a landmark in the developing global body of law on algorithmic labour control, and subsequent courts in other jurisdictions — including Australia and Canada — cited it when addressing analogous gig-worker classification questions.

For the corpus's make-AI-good frame, the ruling is significant because it produced, on the worker-side of the algorithmic management story, what the GDPR Article 22 robo-firing rulings produced on the data-rights side: a high-court confirmation that platform algorithmic systems are not a legally neutral managerial fact but a form of employer control with attendant obligations. The litigation arc that led here — Farrar and Aslam organising the 25-driver claim in 2015, losing their accounts, building the ADCU, and filing the original tribunal claim before either Farrar's 2016 GDPR data-access request or Worker Info Exchange existed — is the organising origin story for the UK platform-worker digital-rights movement the corpus tracks. Without the six-year employment-status litigation, neither the strategic impetus for WIE nor the ADCU's institutional capacity for the subsequent GDPR-Article-22 Amsterdam litigation arc would have taken the form they did.
