Workplace surveillance has become a mainstream feature of modern employment, with a growing number of UK employers deploying digital monitoring tools, commonly referred to as “bossware”, to track employee activity. Recent industry surveys reveal that about one-third of UK firms now utilise such technologies, encompassing email and web browsing monitoring, logging staff logins and logouts, and even reviewing screen activity. While employers commonly defend these practices as necessary for security, productivity, or data protection, the expanding use of digital surveillance has sparked rising concerns about employee privacy, trust, and wellbeing.

The broader social and regulatory context reflects these tensions. The Institute for Public Policy Research and other commentators warn that pervasive surveillance risks undermining workers’ rights and morale, with many employees experiencing increased stress and suspicion about their employers’ monitoring practices. Research further shows that although over half of managers support surveillance to prevent misuse and protect sensitive information, a majority also acknowledge it can damage trust within organisations, signalling a complex cost-benefit balance.

Amid this digital oversight surge, the application of biometric technologies such as live facial recognition (LFR) is attracting particular scrutiny due to its heightened intrusiveness. LFR involves comparing live video footage of faces against watchlists, automatically flagging matches for review, thus raising significant questions about privacy, fairness, and legality. The Equality and Human Rights Commission (EHRC) has intervened in a judicial review questioning the Metropolitan Police’s use of LFR, aiming to determine if such deployment complies with human rights protections under the European Convention on Human Rights, especially regarding rights to privacy, expression, and assembly.

While policing practices are the direct subject of this legal challenge, its outcome is expected to influence private sector employers contemplating biometric or AI-enabled monitoring. Unlike live facial recognition, which collects biometric data indiscriminately from anyone within the camera’s range, other facial recognition technologies, like those used by Uber Eats for worker identity verification, require active participation and consent from the individual. Nonetheless, the Uber Eats Employment Tribunal case, supported by the EHRC, highlighted how racial biases in facial recognition algorithms can disproportionately affect Black and ethnic minority workers, increasing risks of unfair job loss. The case was settled before a precedent-setting hearing but underscored the potential for AI-driven surveillance tools to perpetuate discrimination.

Regulatory bodies are increasingly vigilant regarding workplace surveillance. The UK’s Information Commissioner’s Office (ICO) recently ordered Serco Leisure to cease using facial recognition and fingerprint scanning for staff attendance, ruling the system lacked a lawful basis and was neither necessary nor proportionate. Despite Serco’s claims that the technology was well received by staff, the ICO’s enforcement has prompted other companies operating similar systems to revisit, and in some cases abandon, biometric monitoring. The ICO also warns employers to maintain transparency and proportionality in any form of workplace monitoring, emphasising that employees must be informed about the nature, extent, and underlying reasons for surveillance.

The existing UK legal framework presents a patchwork of overlapping protections through equality, human rights, and data protection legislation. Although private sector employees cannot bring direct claims under the Human Rights Act against their employers, human rights principles influence tribunals and regulators when assessing cases of bias, unfairness, or unlawful data processing. However, much of this legislation predates biometric surveillance and the rise of AI in workplace management, creating grey areas and tensions in applying traditional laws to modern technologies. Independent bodies like the Ada Lovelace Institute argue that piecemeal regulation is insufficient, advocating for a more comprehensive governance framework tailored to biometric technologies.

For employers considering deploying live facial recognition or other biometric surveillance, several critical questions and best practices are advised. These include assessing the necessity of such technology, ensuring accuracy across diverse demographic groups to mitigate bias, providing meaningful alternatives so employees can opt out without penalty, limiting data collection to what is strictly essential, and securing vendor accountability regarding system performance and bias monitoring. Early consultation with data protection, HR, and legal teams, robust impact assessments, transparent communication with staff, and ongoing monitoring for errors or discriminatory impacts are also essential steps to reduce legal and ethical risks.

Looking forward, the judicial review of the Metropolitan Police’s facial recognition use, alongside active regulatory oversight by the ICO, signals heightened scrutiny on biometric surveillance as it extends beyond policing into workplaces. Litigation and enforcement actions are expected to test the boundaries of allowed technology use, especially around concerns of bias and discrimination.

The key takeaway for UK employers is clear: while facial recognition technology can offer operational benefits, its deployment carries significant legal, ethical, and reputational risks. Systems that are inaccurate, intrusive, or imposed without transparent and fair alternatives risk contravening data protection laws and equality principles, inviting regulatory action and potential claims. Necessity, fairness, and proportionality are not abstract ideals but practical tests that will determine the legitimacy of such surveillance as courts and regulators continue to adapt to the challenges posed by AI in the workplace.
