AI Is Making It Cheaper To Sue Your Boss – Are UK Businesses Ready?

The UK’s employment tribunal backlog has doubled in just two years, and lawyers are pointing to an unlikely suspect: the rise of AI. It’s never been easier, or cheaper, for employees to look up their rights, figure out if they have a winning case and draft the paperwork themselves. What used to be a long, expensive process involving a solicitor is now something most people can tackle with a chatbot over a few hours in the evening.

That’s not inherently a bad thing – easier access to justice has genuine social value, and many of the claims now reaching tribunals reflect legitimate workplace issues that previously went unchallenged because the cost of pursuing them was restrictive. But for UK employers and HR teams, the practical reality is that the risk profile of everyday employment decisions has changed. The threshold for taking legal action has shifted, making standard administrative and documentation practices suddenly inadequate.

Which Claims Are Rising And Why

AI is a game-changer for that initial ‘do I have a case?’ question. For claims like constructive dismissal or discrimination, the rules are quite clear-cut, which makes it easy for a chatbot to analyse the facts and give an employee a solid first take on whether it’s worth moving forward. The decision to pursue a claim doesn’t depend on a guaranteed victory. It often comes down to a simple sense of plausibility, which an AI can provide in seconds, turning a doubt into a formal dispute.

Discrimination cases are prime examples of this shift. They typically hinge on the paper trail: if an employer can’t point to solid documentation justifying a dismissal, a denied promotion, or a pay disparity, they are likely to find themselves on the back foot. AI tools are good at helping employees identify where that documentation is likely to be weak or absent, and at drafting the initial ET1 claim form in a way that presents the facts coherently.

Constructive dismissal claims are also rising. These require an employee to demonstrate that their employer’s conduct was so unreasonable they had no realistic option but to resign. The legal test is demanding, but the initial claim is relatively easy to draft, and AI tools can help employees build a coherent narrative from a series of workplace incidents that might previously have felt too diffuse and personal to formalise into a legal case.

What HR Teams Need To Do Differently

The goal isn’t to shift towards a more defensive or litigious culture. It’s about recognising that the informal, handshake style of decision-making is now a major liability, as it fails to stand up to the scrutiny of an AI-supported staff member.

Documentation is the first and most important change. Whether involving a redundancy, a disciplinary outcome or a flexible working refusal, management decisions require a clear, written record of the actual reasoning at the time, rather than a post-hoc rationalisation. This has always been best practice, yet the potential risk of skipping this step is now much higher.

Process consistency carries more weight than it used to. One of the most effective arguments in an employment tribunal is that an employer treated the claimant differently from how it treated others in comparable situations. HR software and workflow tools that enforce consistent processes across dismissals, disciplinaries and performance management lower that risk. The informality that characterises many small and medium-sized businesses – decisions made in conversations rather than written procedures, managers applying their own judgement rather than following a defined process – is the vulnerability that rising tribunal volumes are going to find.

The surge in tribunal backlog brings with it a secondary, often overlooked, complication. Cases are taking longer to reach hearing, which means the period of uncertainty for both parties is extending. A claim lodged today may not reach hearing for 18 months or more in some jurisdictions. That’s a long time to carry the liability, the management distraction and the potential for settlement negotiations to run. Early resolution – either through a thorough internal process that prevents the claim arising, or through ACAS early conciliation once a claim is lodged – is worth more now than it was when the system moved faster.

Is This A Temporary Adjustment Or A Permanent Shift?

This volume increase is structural, not just a cyclical trend. The AI tools that have democratised access to legal claims are becoming more powerful – as the leap from 2024 to 2026 demonstrates, the potential for complainants to build stronger cases is on an upward trajectory.

The tribunal system will eventually adjust – through additional capacity, process reform and the introduction of AI-assisted triage at the tribunal stage itself. But that adjustment will take years, and in the meantime businesses are operating in an environment where employment claims are cheaper to bring, faster to draft and more likely to arrive than they were two years ago.

The businesses that will manage this well aren’t the ones adding more employment lawyers to their speed dial. They’re the ones building the documentation habits, process consistency and HR infrastructure that mean most claims either don’t arise or are easy to defend when they do. The investment required is modest – the cost of not making it has become considerably higher than it was.
