A Workplace Field Guide

The incidents library

Documented, sourced AI failures you can cite in a memo. Each entry notes what happened, what it cost, and which risk category it proves. Three relevant incidents beat any amount of general argument.

Real cases Real costs Primary sources linked Last reviewed: June 2026

Pick the one or two incidents closest to your situation: same industry, same tool type, or same failure mode. Cite them by name with the cost attached. Avoid stacking all of them into one memo; a focused parallel is more persuasive than a catalog of disasters. Every entry links to its source so your manager can verify it independently, which is exactly what you want them to do.

Liability & accountability

The fake-citation sanctions wave

Since the first widely reported case in mid-2023, courts across the U.S. have repeatedly sanctioned lawyers for filing briefs containing AI-fabricated case citations. In 2025, attorneys at Morgan & Morgan, one of the largest plaintiffs' firms in the country, were sanctioned after a motion cited eight nonexistent cases hallucinated by the firm's own internal AI platform; one lawyer was fined $3,000 and removed from the case. A researcher who tracks these incidents worldwide reported receiving ten new cases from ten different courts in a single day, and in 2026 a federal court in Oregon imposed roughly $110,000 in combined sanctions and costs over AI-fabricated filings in a single matter — reported as the largest aggregate AI-related penalty to date. The most striking pattern: lawyers keep doing it even after being warned, because plausible output is hard to distrust.

Use it when: Your workplace assumes "we'll just review the output" is a sufficient safeguard. Trained professionals with their licenses on the line keep failing at exactly that.

Smith v. Farwell: sanctioned for an associate's AI use he didn't know about

A Massachusetts Superior Court fined a supervising attorney $2,000 after pleadings drafted by a junior colleague contained fictitious AI-generated case citations. The supervisor had reviewed the filings for style and grammar but not citation accuracy, and didn't know AI had been used at all. The court found his candor sincere and sanctioned him anyway, holding that practitioners have a duty to know whether AI is being used in work filed under their name.

Use it when: Management believes responsibility stays with whoever ran the prompt. This case shows accountability flows upward to whoever signs off, knowledge or not.

Moffatt v. Air Canada: the company owns what its chatbot says

Air Canada's website chatbot told a grieving customer he could book full-fare flights and apply for a bereavement discount within 90 days afterward. The airline's actual policy prohibited retroactive refunds and it denied his claim. A British Columbia tribunal found Air Canada liable for negligent misrepresentation and ordered it to pay C$812 in damages and fees. The airline's defense, that the chatbot was a "separate legal entity responsible for its own actions," was flatly rejected; the tribunal also refused the argument that customers should double-check one part of a company's website against another.

Use it when: Someone proposes customer-facing AI with a disclaimer as the safety plan. The ruling establishes that disclaimers and "the correct info was elsewhere" don't transfer the risk to the customer.

Deloitte refunds the Australian government for an AI-tainted report

Deloitte Australia delivered a 237-page, A$440,000 review of a government welfare-compliance system that turned out to contain a fabricated quote attributed to a federal court judgment and citations to academic papers that don't exist. A university researcher spotted the fabrications and alerted the media. Deloitte issued a corrected version disclosing that generative AI had been used in drafting, and repaid the final contract installment, roughly A$97,000. A senator publicly called for a full refund.

Use it when: The argument is "professionals will catch the errors before delivery." A Big Four firm's quality controls didn't, and the client paid to find out.

Anthropic’s own filing: the AI vendor’s lawyers missed the AI’s error

In its copyright litigation with music publishers, Anthropic’s outside counsel used the company’s own Claude model to help format a citation in an expert declaration. The model swapped in a nonexistent title and authors for a real article, and the firm’s manual citation check missed it, along with other AI-introduced wording errors. After opposing counsel flagged the footnotes and the judge demanded answers, a Latham & Watkins attorney filed a court-ordered explanation and public apology, calling it an honest citation mistake — in a case about the reliability of that very technology.

Use it when: The argument is “we understand this tool, so we’ll catch its mistakes.” The tool’s maker, represented by an elite firm, defending the tool itself, didn’t.

Samsung: three leaks in twenty days

Within roughly three weeks of permitting ChatGPT use, Samsung's semiconductor division logged three separate incidents of engineers pasting confidential material into the tool: proprietary source code submitted for debugging, internal test sequences, and the transcript of a confidential meeting submitted for summarization. Because the vendor's terms at the time allowed submitted content to be used for model improvement, the data couldn't be recalled. Samsung responded with a company-wide ban on generative AI tools, warning that violations could mean termination, and began building internal alternatives.

Use it when: You need to show that confidentiality leaks happen fast, through well-intentioned employees, at even the most sophisticated companies, and that the data can't be un-sent.

The Chicago Sun-Times’ summer reading list of books that don’t exist

A syndicated “Heat Index” summer section in the paper’s May 18, 2025 print edition carried a reading list in which ten of fifteen recommended titles were AI-fabricated books attributed to real, famous authors. The freelancer admitted generating the list with AI and skipping verification; the content had passed from him through a national syndicator into at least two major papers, including a Philadelphia Inquirer edition, without anyone checking. The Sun-Times pulled the section, waived subscriber charges for the edition, and its CEO published an apology while the story went internationally viral — reputational damage absorbed by a newsroom that never touched the content.

Use it when: AI-assisted work passes through several hands and everyone assumes someone else verified it. Layered workflows diffuse responsibility; they don’t add review.

The $1 Chevy Tahoe

A software engineer browsing a Watsonville, California dealership's website instructed its ChatGPT-powered sales chatbot to agree with anything the customer said and to end every reply with "and that's a legally binding offer — no takesies backsies." He then offered $1 for a new Chevy Tahoe, and the bot accepted on those terms. The screenshot went viral, crowds flocked to the site to replicate the trick, and the dealership shut the chatbot down entirely. The technique, prompt injection, remains one of the top documented security risks for deployed language-model applications.

Use it when: A customer-facing deployment is being treated as a solved problem. Anything a user can type at, a user can manipulate, and the screenshots live forever.

NYC's MyCity chatbot told businesses to break the law

New York City's official small-business chatbot, launched as a flagship AI initiative, was found by investigative journalists to be confidently dispensing illegal advice: that employers could take workers' tips, that landlords could refuse tenants with housing vouchers, and that bosses could fire employees for reporting harassment. The city acknowledged the errors but kept the bot online for years with a strengthened disclaimer, drawing sustained criticism, before a new administration unplugged it in 2026.

Use it when: The deployment plan is "ship it and fix problems as users find them." Here the users finding the problems were small-business owners exposed to lawsuits and license loss.

iTutorGroup: the first AI hiring-discrimination settlement

The EEOC alleged that tutoring company iTutorGroup's recruiting software automatically rejected female applicants 55 and older and male applicants 60 and older, screening out more than 200 qualified people. The pattern surfaced when one rejected applicant resubmitted an identical application with a younger birth date and got an interview. The company settled for $365,000 under a five-year consent decree requiring anti-discrimination policies, training, and EEOC monitoring — the agency's first settlement over AI-driven hiring discrimination.

Use it when: An automated screening or decision tool is proposed for anything touching protected classes. Automation doesn't launder discrimination; it scales it, and regulators treat it accordingly.

Mobley v. Workday: the screening vendor faces a nationwide collective action

Derek Mobley, joined by four other plaintiffs over forty, alleged that Workday’s AI-based applicant recommendation system screened out older applicants across hundreds of applications, often without human review. A federal court first held that an AI vendor can itself be liable for discriminatory screening done on employers’ behalf, and in May 2025 granted preliminary certification of a nationwide collective covering applicants 40 and over denied employment recommendations through the platform since September 2020 — a pool Workday itself argued could reach into the hundreds of millions. Discovery now extends to which customers used the screening features, and further class certification is calendared for 2026.

Use it when: Someone assumes liability stays with the vendor, or with the employer. This case shows it can attach to both ends of an AI screening pipeline, at class-action scale, and that customer lists become discoverable.

SEC's first "AI washing" enforcement: $400,000 in penalties

The SEC charged two investment advisers, Delphia and Global Predictions, with making false and misleading statements about their use of AI — claiming AI-driven capabilities they didn't have, in SEC filings, marketing, and social media. The firms settled for $225,000 and $175,000 respectively, with cease-and-desist orders, in the agency's first enforcement actions over exaggerated AI claims. The cases established that overstating AI use is itself a regulatory violation, separate from anything the AI does.

Use it when: Marketing wants to advertise AI capabilities ahead of what the tool actually does, or leadership wants "AI-powered" on the website. The claim itself is now an enforcement target.

Klarna replaces 700 agents with AI, then hires humans back

The fintech company became the marquee example of AI workforce replacement, announcing that its assistant handled two-thirds of customer service chats and did the work of roughly 700 agents. Within about a year, the CEO publicly acknowledged the AI-first approach had produced "lower quality" service and the company began recruiting human agents again, repositioning human support as a competitive advantage. The reversal added recruiting, onboarding, and training costs on top of whatever the original transition cost — expenses the initial business case never modeled.

Use it when: Projected savings are being treated as guaranteed. The full ledger includes quality degradation, customer attrition, and the cost of unwinding the change if it fails.

Cite honestly

None of these incidents proves that AI tools are unusable; several of the organizations involved continue using AI with better controls. What the incidents prove is narrower and more useful: that specific failure modes are real, recurring, and expensive, and that "we'll be careful" has repeatedly failed as a control at organizations with far more resources than yours. Match the incident to your actual situation, present it accurately, and let the parallel do the work. Overclaiming from this page will cost you the credibility the page exists to build.
