The backlog in single employment tribunal claims across England and Wales is projected to imminently exceed 60,000, driven by an unprecedented surge in both the volume and complexity of cases. This critical threshold underscores mounting pressure on the judicial system, with significant implications for employees seeking justice and employers facing protracted disputes.
Recent minutes from the Tribunal National User Group meeting, held last month and officially published last week, have brought to light the alarming state of affairs. These documents reveal that the number of single claims being received has reached its highest level since the onset of the global pandemic, indicating a robust and sustained increase in workplace disputes. The data paints a stark picture: the average quarterly intake of single claims has escalated dramatically from approximately 7,800 in the 2022-23 period to a forecasted 12,500 by 2025-26. This represents a substantial 60% increase over just a few years. Consequently, the accumulated backlog of outstanding single claims has swelled from 33,000 in the second quarter of 2023-24 to an estimated 58,000 by the third quarter of 2025-26, threatening to surpass the 60,000 mark and continue its upward trajectory.
Understanding the Employment Tribunal System
The Employment Tribunal (ET) system in England and Wales serves as a vital judicial body designed to resolve disputes between employees and employers. Established originally as Industrial Tribunals in 1964, their remit has expanded significantly over the decades to encompass a wide array of employment rights, including unfair dismissal, discrimination, unlawful deductions from wages, and various forms of harassment. They operate as specialist courts, aiming to provide a relatively accessible and cost-effective means of resolving workplace grievances, often without the full formality of higher courts. Historically, these tribunals were intended to offer a swifter resolution process compared to civil courts, making justice more attainable for individuals who might otherwise be deterred by the complexities and costs of traditional litigation. The current crisis, however, challenges this fundamental principle of accessible and timely justice.
Unpacking the "Why": Beyond Economic Cycles
The Tribunal National User Group meeting convened nearly 30 key stakeholders, presided over by Judge Barry Clarke, the President of the Employment Tribunals for England and Wales. During the meeting, Judge Clarke expressed a degree of perplexity regarding the precise causes behind the substantial increase in single claim receipts. He noted a departure from traditional patterns, stating that "The traditional explanation for a growth in receipts, being an economic downturn (reflecting the ET’s historically countercyclical profile), was not at all apparent." This observation is significant because employment tribunals have historically seen an uptick in claims during periods of economic instability, as job losses and corporate restructuring tend to lead to more disputes. The current economic landscape, while facing inflation and cost-of-living challenges, has not presented the kind of severe downturn typically associated with such a surge in tribunal claims.
Instead, alternative theories are emerging. One suggestion, highlighted in the minutes, posits that "more individuals seek to enforce their rights when those rights (or an expansion in those rights) featured more in the news." This points to a potential increase in public awareness regarding employment rights, possibly fueled by media coverage of high-profile cases, legislative changes, or social movements advocating for greater workplace fairness. The digital age, with its rapid dissemination of information and increased public discourse on social justice issues, could certainly contribute to this heightened awareness among the workforce.
The Shifting Landscape of Case Complexity
Beyond the sheer volume, an even more impactful factor identified is the dramatic shift in the "case mix." Fifteen to twenty years ago, "open track claims" — which are typically the most complex cases, often involving intricate issues such as whistleblowing, multiple forms of discrimination, or extensive contractual disputes — constituted a mere 20-25% of all single claims received. The minutes reveal a startling transformation: "That figure has risen steadily in the 2010s, and with unexpected rapidity in the last 2-3 years. That proportion was now 60%. It was closer to 70% in London." This represents a near tripling of complex cases as a proportion of the total caseload, fundamentally altering the operational demands on the tribunals.
Open track cases are inherently more resource-intensive. They require significantly more judicial time, often necessitating multiple preliminary hearings to manage evidence, scope issues, and facilitate case progression. The final hearings for these cases are also considerably longer, frequently spanning several days or even weeks, in contrast to simpler claims that might be resolved in a single day. This shift towards a higher proportion of complex cases directly impacts the tribunals’ capacity to process claims, slowing down the entire system and exacerbating the backlog.
The Unexpected Role of Artificial Intelligence
In a particularly noteworthy observation, Judge Clarke highlighted an anecdotal but increasingly apparent cause for the increased complexity: the use of artificial intelligence (AI). The minutes recorded his assessment that "Anecdotally, the increased use of AI seemed to be at least a partial cause of claims of increased complexity." While AI tools can streamline certain aspects of legal research and document generation, they appear to be contributing to a new layer of complexity within the tribunal system.
Judge Clarke elaborated on this, noting that while "For the moment, it was still relatively easy to spot the use of AI in a document," the collective view among judges was that "AI was likely behind an increase in the complexity of claims, applications for reconsideration and applications for interim relief, as well as inflated schedules of loss." This suggests that AI might be enabling claimants or their representatives to construct more elaborate, multi-faceted claims, potentially identifying more avenues for legal challenge or crafting more expansive arguments for damages. While this might be seen as leveraging technology for a more comprehensive pursuit of rights, it places an additional burden on tribunals, which must then meticulously dissect and adjudicate these increasingly intricate submissions. The increased length of hearings, a direct consequence of this complexity, inevitably reduces the rate at which the tribunal system can dispose of cases, directly fueling the sharp rise in the backlog.
A System Under Strain: Operational Challenges
The strain on the employment tribunal system is not uniformly distributed. The most significant challenges are concentrated in London and the South East, regions that collectively account for half of all tribunal cases initiated in Great Britain. This geographical imbalance presents considerable operational hurdles, particularly concerning judicial resourcing.
Judge Clarke reported on efforts to bolster judicial capacity, specifically the recruitment drive for 36 full-time salaried judges. However, these efforts fell short by 10.5 full-time equivalent (FTE) positions, with the entire shortfall focused squarely on London. The minutes revealed a critical recruitment dilemma: "The president had been faced with a large number of candidates seeking deployment to the non-London locations and who were unable or unwilling to move to London." While measures have been taken, such as persuading new candidates to split their time between London and other regions, the persistent shortage of judges in the capital remains a significant impediment to clearing the backlog.
The impact of these resource constraints is starkly visible in hearing schedules. Five-day hearings in South London are now being scheduled as far out as the first half of 2029, a delay of over four years from the present. In stark contrast, most other regions across England and Wales can still accommodate hearings in 2026 or 2027, highlighting the severe disparity in access to timely justice based on geographical location. This lengthy wait not only causes immense stress and financial hardship for both claimants and respondents but also undermines public confidence in the efficiency and fairness of the justice system.

Expert Perspectives: Legal and Conciliation Views
The implications of this growing crisis resonate deeply within the legal and conciliation sectors. Jainika Patel, a senior associate at Freeths law firm, offered a candid assessment, stating that the figures underscore a challenging reality for employers. "The number of claims is not only rising," she observed, "but they are also becoming significantly more complex; and will likely show no signs of slowing down in light of the Employment Rights Act 2025."
Patel further elaborated on the practical consequences for businesses: "With discrimination cases now forming the majority of new claims, employers face longer delays, heavier procedural demands and escalating costs, often driven by expansive pleadings and inflated claims." She emphasized that the current delays are not merely temporary operational glitches but represent a "structural" issue due to the immense pressure on tribunal resources. For employers, this necessitates a proactive and sophisticated approach: "For employers, this sharpens the need for early risk assessment, disciplined case management and that litigation strategy matters as much as legal merits, in an increasingly congested system." This highlights the critical importance of robust internal HR processes, effective dispute resolution mechanisms, and comprehensive legal advice from the outset of any potential workplace conflict.
Further evidence of the escalating demand comes from Acas (Advisory, Conciliation and Arbitration Service), the public body that provides free and impartial advice to employers and employees on workplace relations. Tony Lowe, Acas’s individual dispute resolution operations manager, provided a written statement to the meeting, revealing record-breaking activity. From April 2025 to February 2026, Acas received over 135,000 early conciliation notifications. This figure represents the "highest number on record by a significant margin," underscoring that a vast number of workplace disputes are arising and seeking resolution, even before reaching the tribunal stage. Early conciliation is a mandatory step before most employment tribunal claims can be submitted, meaning this surge in notifications serves as a leading indicator of future tribunal workload.
The Looming Impact of New Legislation
The landscape of employment rights is set to evolve further with the impending implementation of the Employment Rights Act 2025. While the specifics of this legislation were not fully detailed in the minutes, it is widely anticipated to introduce new protections and expanded rights for employees. Tony Lowe of Acas explicitly predicted that the implementation of these new rights is expected to further increase demand on the conciliation service by an additional 15-20%. This forecast indicates that the current challenges are likely to intensify rather than abate, as employees become empowered by new legal frameworks and seek to enforce their enhanced entitlements. The Act’s provisions, potentially covering areas like flexible working, parental leave, or new forms of discrimination protection, will inevitably generate new types of claims and interpretations, adding another layer of complexity to the tribunal system already struggling under its existing burden.
Broader Implications: Justice Delayed, Justice Denied?
The burgeoning backlog and increasing complexity within the employment tribunal system carry profound implications for all stakeholders.
For employees, the primary concern is access to timely justice. Lengthy delays can lead to prolonged periods of uncertainty, financial hardship if they are out of work, and significant psychological stress. The principle of justice being swift and accessible is severely compromised when individuals must wait years for their cases to be heard. This can erode trust in the legal system and deter some legitimate claims from being pursued, effectively denying justice.
For employers, the implications are equally severe. Protracted disputes mean higher legal costs, extended periods of management distraction, and the potential for reputational damage. The uncertainty of a long-pending claim can also impact business planning and employee morale. Furthermore, the increased complexity of claims, potentially fueled by AI, means that employers must invest more heavily in robust HR practices, legal counsel, and proactive risk management to mitigate exposure. The advice from Jainika Patel about the need for early risk assessment and disciplined case management underscores this critical shift in strategy.
For the justice system itself, the crisis represents a significant challenge to its efficiency, credibility, and capacity. The inability to recruit sufficient judges, particularly in high-demand areas like London, highlights systemic issues within judicial resourcing and potentially judicial remuneration or working conditions. The structural nature of the delay means that piecemeal solutions may be insufficient. A sustained backlog can lead to an accumulation of older, more complex cases, further compounding the problem and potentially overwhelming the system entirely.
Potential Pathways Forward: Addressing the Crisis
Addressing this multi-faceted crisis will require a comprehensive and coordinated approach.
One critical area is increased investment in judicial resources. This includes not only funding for more judges but also addressing the factors that deter candidates from serving in high-demand areas like London. Strategies might include enhanced remuneration, improved administrative support, or more flexible working arrangements.
Procedural reforms within the tribunals could also play a role. Exploring ways to streamline processes for simpler claims, perhaps through enhanced digital tools or revised hearing formats, could free up judicial time for complex cases. However, any reforms must be carefully considered to avoid inadvertently compromising fairness or access to justice.
Enhanced early conciliation and mediation could also be key. Acas already plays a vital role, and further investment in their services could help resolve more disputes before they ever reach the tribunal stage, thereby reducing the incoming caseload. This would require greater awareness among employers and employees of the benefits of early resolution.
Finally, there needs to be an ongoing assessment of the impact of technology, particularly AI, on legal processes. While AI offers potential for efficiency, its current contribution to claim complexity suggests a need for guidelines or perhaps even new procedural rules to manage AI-generated content within legal submissions, ensuring it aids clarity rather than obfuscation.
The impending breach of the 60,000-claim backlog threshold for single employment tribunal cases is more than just a statistic; it is a stark indicator of a justice system under immense duress. The confluence of rising claim volumes, escalating complexity driven partly by technological advancements, and persistent resource shortages, particularly in key regions, presents a formidable challenge. Without urgent and strategic intervention, the promise of timely and accessible justice in the workplace risks becoming an increasingly distant reality for thousands across England and Wales.
