Is using AI for Employment Law advice putting your business at risk in 2026?

Key takeaways: 

  • Tribunal claims are climbing fast: Employment tribunal claims rose 39% year on year, according to GOV.UK’s quarterly tribunal statistics 
  • AI-built disputes are a growing factor: Citation’s Employment Law specialists link part of that rise to employees and employers building cases on AI advice with nobody qualified checking it first. 
  • Grievance letters are getting much longer: AI-generated letters can stretch to fifteen or twenty pages, compared to the couple of pages typical of one an employee writes themselves. 
  • You can’t take back AI-drafted correspondence: Once it’s gone out in your name, it can be used against you at tribunal, even if AI wrote it. 
  • SMEs carry the most risk: SMEs (small and medium-sized enterprises) are less likely to have in-house legal or HR expertise checking AI output before they act on it.

 

If you’ve used ChatGPT or another popular AI tool to draft a dismissal letter or a response to a workplace complaint, you’re not alone. It’s being called “vibe lawyering”, and it’s part of why employment tribunal claims are climbing across the UK.  

GOV.UK’s Tribunal statistics quarterly: January to March 2026 shows employment tribunal claims have risen 39% year on year. Citation’s own analysis of the claims it’s supported clients with this year found the care sector accounts for 28.5% of them – nearly double any other sector category. Our Employment Law specialists say growing AI use on both sides of workplace disputes is part of the reason. But the risk particularly comes from treating AI’s answer as the final word instead of a first draft, not from using AI in general. 

What is “vibe lawyering”?  

Vibe lawyering means using AI to carry out legal work, for example draft a grievance letter, build a case for compensation, or write a dismissal letter, without a qualified person checking the reasoning or the tone first. The term is a spin-off of “vibe coding” – describing what you want in plain English and letting AI write it – and was popularised in a legal context by The Economist’s report on the rise of vibe lawyering. The danger is treating a confident-sounding AI answer as settled advice instead of a first draft. Employees use it to build a case from their own account of events, while employers use it to draft dismissal letters and responses to complaints. Either way, skipping the expert check is where it can go wrong. 

Why are employment tribunal claims rising in 2026?  

Employment tribunal claims rose 39% year on year, according to GOV.UK’s quarterly statistics. Citation’s Employment Law specialists partly put that down to AI making it faster, cheaper and less intimidating to act on a grievance than it used to be.  

Gill McAteer, Director of Employment Law at Citation, says: “Where AI really shines is speed – summarising a mountain of correspondence or giving someone a sensible starting draft in minutes rather than hours. That’s a real win for time-poor SMEs. But employment law is different because so much of it is underpinned by nuance and the concept of reasonableness, which AI still struggles to grasp.” 

Add ongoing reform under the Employment Rights Act 2025 (ERA), and AI’s grip on recent legal developments gets even shakier, because the rules themselves are still moving.  

Who’s most exposed to AI-driven workplace disputes?  

If you run an SME, you’re carrying the most risk. Larger organisations usually have in-house legal or HR expertise to fall back on – you probably don’t, which is exactly why you’re more likely to reach for a free AI tool when a complex employee issue lands on your desk. Without someone to check the answer against your own situation, it’s hard to spot where the AI’s got it wrong, especially when it sounds so confident.  

How is AI changing the way employees raise grievances?  

If you’ve handled a grievance letter recently, you’ll have noticed they’re getting longer. 

Gill McAteer says: “Whereas grievance letters written by employees tend to be a couple of pages long, AI-generated grievance letters can now stretch to fifteen or twenty pages and are often so repetitive and bogged down in technical terminology that employers “can’t see the wood for the trees.”” 

This means the actual complaint gets buried under pages of AI padding, making it harder to work out what’s being alleged and what you need to do about it.  

Can AI-drafted letters be used against you at tribunal?  

Yes. Once you’ve sent AI-drafted correspondence to an employee, you can’t disown it afterwards by saying AI wrote it because it went out in your business’s name. AI-written letters often read well on the surface but bury damaging wording, ramble past the point you needed to make, or jump ahead of where the process has got to. For example, they might raise dismissal before it’s even been discussed as an option. If that wording later hands the other side legal ammunition, it can be used against you. If you’re already facing a claim, read what to do when an employment tribunal claim is made for the practical next steps. 

What’s the risk with AI and probationary dismissals?  

Citation’s Director of Employment Law, Gill McAteer, cites probationary dismissals as a common blind spot: “AI will readily and accurately walk an employer through a standard dismissal process step by step – that part it does well. What it has no way of flagging is that the same employee raised a safeguarding concern weeks earlier.” 

“If this fact is overlooked by the employer inputting the information, it can quickly turn a routine dismissal into a potential whistleblowing claim worth tens of thousands of pounds in damages,” she adds. 

It’s important to remember that two dismissals that look identical on paper can call for completely different handling and responses, depending on facts that never made it into the original AI prompts. 

What should you do before using AI for workplace issues?  

Do this  Because 
Treat AI’s answer as a starting point, not a final position  It doesn’t know your business, your policies or the facts of your case, and it’s shaky on recent changes like the ERA reforms 
Get a qualified person to check any AI-drafted letter before you send it  Once it’s gone out in your name, you can’t take it back at tribunal 
Question one-sided AI-generated grievances  AI builds a case from one account only, so investigate before you treat anything as settled fact 
Remember AI can’t weigh up your case’s specific circumstances  Two similar cases can need very different responses 
Use AI for speed on simple, factual work and bring in a person for judgement calls  Decisions have to stay with you, not the AI

What is "vibe lawyering"?

Vibe lawyering is using an AI tool like ChatGPT to build a legal argument or draft workplace correspondence - for example a grievance letter, a dismissal letter, a compensation claim - without a qualified check before it's used.

Is it safe to use ChatGPT to write a dismissal letter?

Not on its own. AI can describe a standard dismissal process accurately, but it can't flag facts you didn't tell it, like a recent safeguarding concern. You should always get someone qualified to check the letter before you send it.

Can AI replace HR or legal advice in employment disputes?

No. Employment Law depends on judgement and reasonableness applied to your specific case, and that's true even if you fed an AI thousands of past cases for context.

Why have UK employment tribunal claims risen in 2026?

They rose 39% year on year, according to GOV.UK's Tribunal statistics quarterly: January to March 2026. There are lots of reasons tribunal claims have risen in 2026, but Citation's specialists partly put it down to AI making it easier and cheaper for employees to bring a claim.

What is the Employment Rights Act (ERA) reform?

It's the legislation reshaping Employment Law in Great Britain through 2026 and 2027. AI tools are particularly unreliable here because the rules themselves are still changing.

Can you ignore a lengthy AI-generated grievance letter?

No. Even if it runs to fifteen or twenty pages and reads as repetitive, you still need to establish the substance of the complaint and investigate it properly.

What happens if you send AI-drafted correspondence to an employee?

It could be used against you at tribunal. Once it's gone out in your name, you can't disown it by saying AI wrote it.
