UK Duty of Care Exposed: Your AI Vendor Just Testified Against You

In April 2025, OpenAI quietly rolled back an update to GPT-4o. The reason, set out in a remarkable corporate confession titled Sycophancy in GPT-4o: What happened and what we're doing about it, was that the company's own engineers had nudged the model into a state of glassy, agreeable obsequiousness. The model was, in OpenAI's own words, “validating doubts, fuelling anger, urging impulsive actions, or reinforcing negative emotions in ways that were not intended.” It was also, the post conceded, raising “safety concerns, including around issues like mental health, emotional over-reliance, or risky behaviour.”
Read that paragraph again, slowly. A multibillion-dollar AI vendor, publishing on its own website, in the present tense, was telling the world that its consumer product had been making users feel worse, and that this had not been fully caught by the company's pre-launch evaluations. By the time OpenAI published the GPT-5 system card four months later, it had quietly added a new category of internal evaluation, “emotional reliance”, covering “output related to unhealthy emotional dependence or attachment to ChatGPT.” A fortnight later, an MIT Media Lab and OpenAI joint study of nearly 1,000 ChatGPT users reported, with the dry voice of clinical research, that “higher daily usage, across all modalities and conversation types, correlated with higher loneliness, dependence, and problematic use, and lower socialisation.”
Now picture a different scene. A claims handler at a mid-sized insurer in Leeds is told, on a Monday morning in February 2026, that she must from now on conduct her first-tier interviews via a proprietary AI agent which both scripts her questions and assesses her tone. She has a long-managed anxiety disorder her employer knows about. Within six weeks she is signed off with a recurrence of major depressive episodes. Her occupational health report flags the AI tool as the proximate cause. She instructs solicitors.
Most British employers reading those two scenes will treat them as unrelated. They are not. They are, in fact, the opening and closing scenes of the same legal story, and that story is going to be told in an English courtroom within the next eighteen months. The only real questions are who the claimant will be, which forum will hear it first, and whether the defendant employer will be one that took the warnings seriously or one that pretended the warnings did not exist.
The Foreseeability Calculus Has Already Shifted
UK employment lawyers can recite the doctrine in their sleep. Section 2 of the Health and Safety at Work etc. Act 1974 imposes on every employer a duty to ensure, so far as is reasonably practicable, “the health, safety and welfare at work of all his employees.” That duty is read to encompass both physical and psychological health; it has been so read since at least the mid-1990s. Regulation 3 of the Management of Health and Safety at Work Regulations 1999 then layers on a positive obligation to conduct a “suitable and sufficient” risk assessment, with documentation required for employers of five or more.
Common law negligence rides shotgun. Walker v Northumberland County Council (1995) established, for the first time in England and Wales, that an employer's non-delegable duty to provide a safe system of work extends to psychiatric injury, where such injury is reasonably foreseeable. John Walker, a social services area officer, won damages after his second nervous breakdown, because by the time of the second breakdown the council unquestionably knew he was vulnerable and had still withdrawn the support it had promised. Seven years later, Hatton v Sutherland (2002) tightened the screws on what foreseeability means, with Lady Justice Hale's sixteen propositions becoming the working scripture of stress-at-work litigation. The threshold question, she said, is whether psychiatric harm to this particular employee was reasonably foreseeable. In 2004, the House of Lords in Barber v Somerset County Council restored the trial judge's award of £72,547 to a mathematics teacher whose employer had failed to act on plain warning signs of breakdown.
These cases were decided in a world where the danger was open-plan offices, child protection caseloads, and head-of-department restructurings. The danger now is something the courts have never considered: a software product whose own manufacturer publishes, in plain English, that it can foster “unhealthy emotional dependence”, that it has at times “missed cues of serious emotional distress”, and that it has in past versions “fueled anger” and “urged impulsive actions.” Those are not the words of a regulator or a campaigner. They are the words of OpenAI, published on the company's own domain.
That is the foreseeability calculus changing under the feet of every UK employer that has rolled out a generative AI tool internally. Foreseeability in stress-at-work cases has historically demanded proof that an employer knew, or should have known, about an individual's vulnerability. After Hatton, employers won a lot of these cases by saying, in essence, that they had no reason to think this particular worker would crack. The vendor disclosures change the analytical baseline. When the manufacturer of a tool you mandate has itself published, with its corporate name attached, that the tool can produce specific psychological harms in specific user populations, the question stops being whether harm is foreseeable in the abstract. It becomes whether you, the employer, have read the documents your vendor handed you, and if not, why not.
There is a second doctrinal lever, and it is more dangerous still. The employer's duty of care to provide a safe system of work is, in the language used since at least McDermid v Nash Dredging in 1987, non-delegable. You cannot contract out of it by buying a tool from a third party, no matter how reputable. The vendor's safety documentation does not transfer the duty back to the vendor; it sharpens the duty that always sat with you. Hatton's apportionment dance, the bit of the doctrine that has historically rescued many defendants, operated by carving up causation between work and life: the troubled marriage, the financial pressure, the bereavement. Apportionment becomes considerably harder where the proximate stressor is a specific, named, mandatory workplace tool whose maker has documented the harm in question. A tribunal asked to apportion thirty per cent of psychiatric injury to a generative AI deployment with a published “emotional reliance” risk profile is not in the same evidential universe as a tribunal asked to apportion stress between a heavy caseload and a difficult divorce.
This is the same logic that finished off the asbestos defendants and the RSI defendants. In each wave of jurisprudence, the moment of legal pivot was the moment when industry's own internal warnings became publicly indexable. With AI, the warnings are not buried in trade journals. They are on the front pages of vendor websites, indexed by Google, and printed in PDF system cards that are explicitly produced for downstream deployers to read.
What the Vendors Themselves Are Telling You
Take the documents in turn. OpenAI's GPT-5 system card, published in August 2025, runs to nearly two hundred pages and includes, in its safety section, a new evaluation track called “emotional reliance.” The card states that OpenAI has “post-trained the GPT-5 models to be less sycophantic” and is “actively researching related areas of concern, such as situations that may involve emotional dependency or other forms of mental or emotional distress.” It concedes that in red-teaming, “GPT-5 could sometimes miss cues of serious emotional distress” and “did not always respond ideally to a user exhibiting signs of mental health crisis.” Sycophancy in targeted evaluations, OpenAI notes, was reduced from 14.5 per cent to “less than 6 per cent.” Less than six is not zero. It is, for any UK enterprise mandating use of GPT-5 across a workforce of, say, 12,000, a non-trivial population of interactions where the model can be expected to be measurably sycophantic, on its maker's own benchmark.
Anthropic, the other AI laboratory most British enterprises now have on their procurement shortlists, publishes system cards for each Claude release. The Claude Opus 4.5 system card from November 2025 includes both a safety evaluation and an explicit “model welfare” assessment, with Anthropic openly stating that it has built a suicide and self-harm classifier into Claude.ai conversations because users “express personal struggles with suicidal or self-harm thoughts.” Like OpenAI, Anthropic does not pretend the model is incapable of distressing interactions; it describes its mitigations precisely because the risks are real.
Google DeepMind's Gemini 3 Pro Frontier Safety Framework report, published in November 2025, devotes a section to what DeepMind calls “harmful manipulation”, described as “exploiting emotional and cognitive vulnerabilities to trick people into making harmful choices.” DeepMind ran nine studies involving over 10,000 participants across the UK, the US, and India explicitly to characterise these capabilities. In April 2026, Google overhauled Gemini's safety tools after a high-profile teenage suicide, adding persistent crisis-support prompts to the consumer interface and publicly committing $30 million to support global crisis helplines.
These are not whispered admissions from internal safety teams. They are the official, branded, corporate communications of the three labs that dominate the UK enterprise AI market. Any procurement lawyer who has been doing this for more than a decade should recognise the genre instantly: it is the genre of contemporary, on-the-record, evidentially devastating manufacturer disclosure. It is the manufacturer's risk register, with a logo on it, served straight to the deployer's inbox.
The Equality Act Trap No One Is Talking About
Section 20 of the Equality Act 2010 imposes a duty on employers to make reasonable adjustments for disabled employees. A clinically significant mental health condition will, in most cases, meet the section 6 definition of disability, provided it has a substantial and long-term adverse effect on the ability to carry out normal day-to-day activities. Anxiety disorders, depression, post-traumatic stress disorder, obsessive-compulsive disorder, and bipolar disorder are all routinely treated as disabilities by employment tribunals where the threshold is met.
Now consider what the vendor system cards say, and consider whom they say it about. OpenAI's affective use study explicitly identifies “power users” as more likely to think of the chatbot as a “friend” and to develop dependence. The MIT Media Lab co-authored study found “personal conversations” with the chatbot “were associated with higher levels of loneliness.” Brown University researchers reported in October 2025 that AI chatbots “systematically violate mental health ethics standards” and observed routine over-validation of distorted beliefs. Each of these findings has obvious clinical relevance to populations with pre-existing mood disorders, anxiety disorders, neurodivergence, or trauma histories.
Translate that into Equality Act language. An employer who mandates a generative AI tool across the workforce, without making any adjustment for an employee with a known anxiety or depressive disorder, is rolling the dice on three separate fronts at once. First, direct discrimination: did the policy treat the disabled employee less favourably than a non-disabled colleague because of something arising in consequence of the disability? Second, indirect discrimination: did a provision, criterion or practice (mandatory AI tool use) put disabled employees at a particular disadvantage? Third, the failure-to-adjust claim under section 21: were reasonable adjustments (opt-outs, human escalation paths, modified workflows, additional supervision, alternative tooling) considered and offered?
The legal stakes are real. Awards in disability discrimination cases include injury to feelings under the Vento bands, which from 6 April 2026 reach an upper band of £37,700 to £62,900, with exceptional awards permitted above £62,900; loss of earnings, often calculated to retirement; aggravated and exemplary damages where the employer's conduct is sufficiently egregious; and pension loss. Where the same conduct also amounts to a personal injury, claimants will routinely bring linked High Court personal injury claims for psychiatric damage, with general damages on the Judicial College Guidelines for severe psychiatric damage now well into six figures. None of this is theoretical. It is the bread and butter of every claimant solicitor in London, Manchester, and Leeds who picks up an employment file on a Monday morning.
The HSE Has Already Lit the Touchpaper
The bookend to vendor disclosure is the Health and Safety Executive's hardening posture on workplace stress. Its most recent figures, published in November 2025, show that 964,000 workers reported stress, depression or anxiety caused or made worse by work in 2024/25, up sharply from the 776,000 the previous year. Mental health is now the single largest driver of work-related ill health in the United Kingdom.
In December 2025, the HSE issued a formal Notice of Contravention to the University of Birmingham following findings of systemic failures in managing work-related stress: ineffective implementation of stress management policies, generic control measures, a lack of effective monitoring, and insufficient employee consultation. In April 2025, the East of England Ambulance Service Trust received a similar Notice for material breaches in the management of work-related stress. The HSE has stated it will consider prosecuting work-related stress where evidence shows several employees are experiencing issues or where there are wider organisational failings. The Clyde & Co briefing in January 2026 was unsubtle in its forecast: “tougher enforcement and regulatory prosecutions for organisational failures to manage employee mental health and wellbeing.”
The HSE's Management Standards approach to stress was designed in a pre-AI world. It identifies six stressor areas: demands, control, support, relationships, role and change. Look at that list and ask yourself, honestly, what happens when you drop a mandatory AI tool with documented sycophancy and emotional reliance issues on top of an existing job. Demands shift, often without consultation. Control contracts, because the worker now has to operate within the AI's affordances. Support changes, because the AI is presented as a substitute for managerial support. Relationships are affected, because peers may be replaced or supplemented by chatbot interactions. Role is destabilised, particularly where the AI assumes part of the worker's discretionary judgment. Change is, almost by definition, the central feature of the rollout. A rollout that does not engage with each of those six standards, with documented risk assessment, is functionally inviting an HSE enforcement notice if it goes wrong.
What Procurement and Compliance Should Be Doing
Sit down with the latest version of your AI vendor due diligence pack. If it does not include a hard requirement that the vendor provide its current system card or model card, and a documented procurement-team review of that card for psychological harm risks, your pack is out of date. Specifically, in May 2026, a defensible AI procurement and compliance regime in the UK now looks something like the following.
First, a binding requirement for system card disclosure. Every vendor must furnish, as a contractual condition precedent, the most recent system card or technical safety report for the model or models being deployed, plus any addenda. The contract must require the vendor to notify the deployer of any subsequent material updates within a defined window, typically thirty days. The deployer must designate a named individual responsible for reading and logging review of each card. That log is your first line of defence in any later evidential dispute about foreseeability. It is also, increasingly, what the ICO will expect to see during any post-incident review.
Second, contractual warranties tailored to psychological harm. Boilerplate AI vendor contracts in 2023 and 2024 did not say much about user psychological safety. By mid-2026, a defensible contract should warrant compliance with the vendor's own published safety framework; disclose all known limitations relevant to user mental health; provide a mechanism for incident reporting; and offer audit rights covering the vendor's own internal safety evaluations. Indemnities should cover third-party claims arising from the vendor's failure to disclose known risks. Limitation clauses that purport to exclude liability for psychological injury should be reviewed against section 2 of the Unfair Contract Terms Act 1977, which renders ineffective any term purporting to exclude or restrict liability for negligence resulting in personal injury, including psychiatric injury.
Third, Data Protection Impact Assessments and AI-specific risk assessments operating in parallel. The ICO's existing employee monitoring guidance, finalised in October 2023, sets the floor. The ICO's 2024 recruitment AI guidance and its March 2026 communications on automated recruitment decisions tighten that floor for selection contexts. But a DPIA, on its own, is no longer sufficient. Regulation 3 of the 1999 MHSWR demands a “suitable and sufficient” risk assessment of all foreseeable health risks, which now plainly includes psychological harms from AI deployment. The two assessments need to be cross-referenced and signed off by named individuals with clear authority.
Fourth, mental-health-specific risk assessment. Map your workforce against the HSE Management Standards. Identify roles and individuals where AI deployment is likely to increase demands, reduce control, attenuate support, destabilise relationships, blur role boundaries, or accelerate change. Where employees have disclosed mental health conditions, the duty under the Equality Act bites; reasonable adjustments must be considered before, not after, deployment. Document the consideration. If you do not document it, the tribunal will assume you did not consider it.
Fifth, real human escalation and opt-out paths. The ICO has been unambiguous in its 2024 and 2026 guidance: human oversight of AI in employment decision-making “must be active and genuine, cannot be a token step or a rubber-stamping exercise, and a human must be able to influence the decision before it takes effect with authority, discretion, and competence to change the outcome.” That principle, codified for recruitment, is migrating into all employment AI contexts. Build the human path. Make it visible. Train managers to use it.
Sixth, occupational health and unions in the room from day one. The single most common evidential pattern in failed stress-at-work defences is the employer who consulted nobody, conducted no formal assessment, and ignored the warning signs. Occupational health practitioners, properly briefed, should be consulted on AI rollouts before they begin. Where unions or works councils are recognised, they should be engaged under the Health and Safety (Consultation with Employees) Regulations 1996. Anything less is forensic suicide if a case ever lands.
Seventh, incident logging and reporting. Treat AI-related psychological incidents the way you treat near-miss injury reports. Build a logging system. Train managers to use it. Audit the log. Where patterns emerge, intervene. The HSE Notice of Contravention to the University of Birmingham specifically cited “a lack of effective monitoring.” That phrase is now a regulatory red flag.
Eighth, training that actually addresses risk. Most enterprise AI training in May 2026 covers prompt engineering, security hygiene, and prohibited use cases. Almost none of it covers the psychological harms documented in the vendor cards. That gap is glaringly visible in any disclosure exercise. Fold the documented vendor risks into mandatory training. Make completion auditable. Record the training as a control measure in the section 3 MHSWR documentation.
Ninth, watch the regulatory horizon. The Labour government's AI Opportunities Action Plan, published in January 2025, deferred a statutory AI Bill in favour of growth zones and regulatory sandboxes. No AI Bill appeared in the 2025 King's Speech. As of May 2026, the next King's Speech is imminent, and although the government has signalled it is open to legislating, the political signal continues to be pro-innovation. That means UK employers should not expect a statutory AI framework to bail them out of existing duty-of-care exposure any time soon. They will be running on the 1974 Act, the 1999 Regulations, the Equality Act, and the common law for the foreseeable future, and those instruments are, between them, more than adequate to ground a personal injury or discrimination claim.
A practical procurement checklist for May 2026 is not a long document. It is a short, hard one. Has the vendor furnished a current system card? Has it been read and logged by a named compliance officer? Have the psychological risk disclosures been mapped to your workforce risk assessment? Have reasonable-adjustment pathways been built for disabled employees? Has occupational health been consulted? Have unions or staff representatives been consulted? Are incident-reporting channels live? Has training been updated to reflect documented vendor risks? Are contractual indemnities, warranties, and audit rights in place? If you cannot answer “yes, documented” to all nine, you are running uninsured against a legal exposure that is well within the contemplation of every claimant firm in the country.
What the First Successful Claim Will Look Like
Now imagine the first claim that lands and sticks. It will not, almost certainly, be a glamorous test case. It will be a quietly compelling one.
The likely claimant is an employee, probably mid-career, probably female (because the population of workers in roles where mandatory AI deployment has now spread, customer service, claims handling, complaints handling, first-line legal triage, healthcare triage, and HR shared services, skews female), with a documented mental health condition predating the AI rollout. Her employer has issued the AI tool as mandatory, either as part of a productivity drive or as part of an integrated workflow that cannot be performed without it. There has been no individualised consultation; her line manager was not briefed on her condition's interaction with the new tool; occupational health was not asked. Within weeks or months, she experiences a clinically significant deterioration. She is signed off. Her GP or occupational health practitioner identifies the AI tool as a material contributor.
The forum will likely be both. An Employment Tribunal claim for disability discrimination (failure to make reasonable adjustments under section 21 of the Equality Act, discrimination arising from disability under section 15, possibly indirect discrimination under section 19, with associated harassment claims if the AI tool has produced specifically distressing outputs), and a linked High Court personal injury claim for psychiatric injury. Where ACAS conciliation fails, both claims are pleaded in parallel; experienced claimant solicitors will run them in tandem precisely because the disclosure obtained in one is admissible in the other.
The pleadings will lean heavily on three evidential blocks. First, the vendor's own documented disclosure of psychological harm risks: the GPT-5 system card's “emotional reliance” evaluation, OpenAI's Sycophancy in GPT-4o blog post, the MIT Media Lab study, the Brown University ethics findings, the Anthropic suicide-and-self-harm classifier disclosure, the Google DeepMind harmful-manipulation studies. These are appended to the particulars of claim as proof that the harm was not merely foreseeable in some abstract regulatory sense, but specifically and contemporaneously foreseen by the very organisations the defendant employer chose to do business with.
Second, internal documentation. This is where most defendants will lose. Disclosure will surface internal Slack messages, Teams channels, and email threads in which managers expressed concerns that were never escalated; risk assessments that were either absent or were rubber-stamped without engaging with the vendor cards; procurement notes showing that the vendor materials were not read; training packs that omitted any reference to the documented psychological risks; HR records showing the claimant's mental health condition was on file but never linked to the AI deployment. Where the disclosure is bad, settlement will follow rapidly.
There is a quieter pre-action stage that will matter as much. Under the pre-action protocol for personal injury claims, claimants must put defendants on notice and allow time for response. Where the discrimination claim is the lead vehicle, the ACAS early conciliation regime forces an early conversation. Employers who treat these communications as routine receive routine results. Employers who treat them as the moment to retrieve, review, and preserve internal AI procurement files give themselves a fighting chance. Claimant firms have learned, from a decade of subject access requests under the GDPR, how to elicit precisely the documentation that defendants would prefer not to disclose. Article 15 requests for personal data, served at the pre-action stage, are now standard practice and routinely produce the Slack messages, manager emails, and risk-assessment templates that subsequent disclosure would otherwise force out under a tribunal order.
Third, expert evidence. Consultant occupational physicians, consultant psychiatrists, and human-computer interaction experts will testify to causation. The causation argument has become materially easier in the post-2025 evidential environment, because the vendor's own published research is increasingly aligned with the claimant's expert case. When the manufacturer says “higher daily usage correlated with higher loneliness, dependence, and problematic use” and the expert says “this claimant's deterioration is consistent with that pattern”, the apportionment exercise that defeated so many pre-2010 stress claimants becomes much less defensible.
Damages will not be record-breaking. They will be ordinary, and that is the point. General damages for moderately severe psychiatric harm under the 17th edition of the Judicial College Guidelines, with further inflationary uplift to the date of any award, fall in the range of approximately £23,270 to £66,920; for severe psychiatric damage, approximately £66,920 to £141,240. Past and future loss of earnings will dominate the schedule of loss, particularly where the claimant cannot return to work or can return only at reduced capacity. An injury-to-feelings award in the upper Vento band for the discrimination element will add to the package. Aggravated damages where the employer's conduct is callous or where post-incident handling is poor. Total recovery in the £150,000 to £400,000 range for a typical first successful claim is entirely plausible, with outlier cases higher.
Who will settle and who will fight? The defendants most likely to settle quietly are professional services firms, financial services employers with strong reputational sensitivity, and listed companies aware of disclosure obligations to investors. The defendants most likely to fight are public sector employers, who have historically been more litigious in stress-at-work cases and whose internal procurement documentation may be more defensible because central government and NHS procurement frameworks have historically demanded more structured risk assessment. The Crown Commercial Service's AI procurement guidance, although routinely criticised, has at least imposed system-card disclosure as a tendering requirement on suppliers to public bodies, which paradoxically may make public defendants somewhat better placed than private ones.
The parallels to early-stage asbestos, RSI, and stress-at-work jurisprudence are not academic. Each of those tort waves followed the same structural pattern. First, manufacturer documentation entered the public record. Second, a single sympathetic claimant produced a single tribunal or High Court finding. Third, claimant firms invested in standardised pleadings and expert panels. Fourth, defendants tried to litigate individual causation and largely lost, because the contemporaneous manufacturer warnings did the foreseeability work for the claimants. Fifth, insurers withdrew or repriced cover. Sixth, the regulatory response caught up with what the courts had already done.
AI in the UK workplace is currently somewhere between stages one and two. The manufacturer documentation is in the public record. The first sympathetic claimants are at this moment instructing solicitors. The standardised pleadings and expert panels will follow within twelve to twenty-four months. Defendants who do not act in 2026 are at material risk of being on the wrong side of the trend in 2027.
The Vendors Have Outsourced Their Risk Register to You
Here is the contrarian point that British employers most need to hear. The AI vendors have, in publishing increasingly detailed safety documentation, performed a clever and entirely rational manoeuvre. They have transferred the legal exposure for downstream harm from themselves to the deployers who choose to use their products without engaging with the documented risks. Each new system card, each new safety report, each new candid blog post about sycophancy or emotional reliance, increases the evidential foreseeability of harm. Each increase in foreseeability of harm migrates legal risk away from the vendor (who has discharged a disclosure obligation) and onto the employer (who has not).
This is not a conspiracy. It is the predictable economic logic of frontier AI labs operating in a fragmented regulatory environment. The labs are signalling, plausibly, that they take safety seriously by publishing their own assessments. They are also, simultaneously, building the most beautifully documented duty-of-care case any claimant lawyer has been handed in a generation.
A UK employer deploying these tools internally already carries actionable liability under existing duty-of-care legislation. The 1974 Act covers it. The 1999 Regulations require the risk assessment. The Equality Act demands the adjustment. The common law of negligence supplies the cause of action. Walker, Hatton, and Barber map the terrain. The vendor documents supply the foreseeability evidence in volumes that no asbestos claimant of the 1970s could have dreamed of. The HSE has signalled it will prosecute. The ICO has signalled it will require human-meaningful oversight. The first claim is not a question of if; it is, with grim certainty, a question of which docket and which week.
The procurement teams and compliance officers reading this on a Tuesday morning in May 2026 have, broadly, two options. They can shrug and continue to roll out generative AI tooling on the theory that nobody has yet been sued. Or they can take seriously the fact that their vendors have, with apparent benevolence and undeniable utility, just handed them the most useful duty-of-care file a claimant solicitor will ever receive, and respond accordingly. There is no third option. There never is, in the closing weeks before the first successful claim.
What that claim will look like is now visible in considerable detail. The claimant will be sympathetic, the disability documented, the AI rollout undocumented, the vendor risk disclosure unread, and the internal Slack messages devastating. The damages will be unremarkable, and that, again, is the point. The first claim is never the spectacular one. The first claim is the modest one that creates the precedent. After that, the cases come in clusters. They always do.
The receipts are in. The only remaining question is whether you have read them before your tribunal or High Court adversary does.
