The UK Employment Tribunal Backlog: Why Justice Is Taking So Long and What Can Be Done

The UK Employment Tribunal system is facing unprecedented pressure. For many employees and employers, what was once a process measured in months is now stretching into years. In some cases, claimants are being told their final hearing may not take place until the end of the decade. This level of delay is more than an inconvenience, it has serious consequences for justice, wellbeing, and business certainty.

How long does one need to wait?

Recent data and investigative reporting paint a stark picture. According to Ministry of Justice statistics, the number of open employment tribunal cases has increased sharply, with single-claim backlogs now at their highest level since records began. In practical terms, many claimants are experiencing average waiting times of at least 12 to 18 months from issuing a claim to receiving a final hearing, and considerably longer in complex cases, particularly in London and the South East of England.  

It has been reported that some tribunals are already listing hearings as far ahead as 2029 or 2030, particularly for longer discrimination and whistleblowing cases. These delays risk turning access to justice into little more than a theoretical right.

Why is the tribunal system struggling?

The backlog is driven by a combination of structural and political factors rather than a sudden increase in weak or speculative claims.

  1. A surge in claims and complexity
    Many modern claims are legally and factually complex, particularly discrimination, whistleblowing, and harassment cases. Such claims require longer hearings, the discussion of multiple preliminary issues, and extensive case management.
  1. Insufficient judicial capacity
    While claim volumes have risen, tribunal resources have not kept pace. Reports show that the number of sitting days and judges has fallen in real terms, particularly in London where caseloads are significantly higher than in other regions.
  1. Legislative change without matching funding
    Recent and forthcoming employment law reforms are expected to increase the number of potential tribunal claims further. However, without sustained investment in the tribunal system itself, these changes risk worsening the backlog rather than improving workplace justice.

For employees, prolonged proceedings can cause financial strain, stress, and prolonged uncertainty. Many are forced to abandon valid claims or accept lower settlements simply to move on with their lives. For employers, unresolved claims represent long‑term risk. Key witnesses may leave the business, memories fade, and management time is repeatedly diverted to a dispute that cannot be concluded.

It is likely that any meaningful improvement will require increased and sustained funding for employment tribunals and certainly the recruitment and retention of salaried employment judges. However, these are long‑term solutions and unlikely to deliver quick relief for those currently facing claims.

How can we help you in the meantime?

Admittedly, we cannot eliminate tribunal delays, however, we can help our clients navigate the system far more effectively by:

  1. Providing early strategic advice
    Many disputes can be resolved before a claim is even issued. Early advice can help employers assess risk realistically and explore alternatives such as settlement.
  1. Robust case management
    Where claims do proceed, careful preparation from the outset such as identifying witnesses early, and narrowing issues, can significantly reduce the risk created by long delays.
  1. Pragmatic settlement strategy
    With hearings so far away, commercial settlement discussions are increasingly shaped by time and cost considerations. We can help parties reach outcomes that reflect both legal merits and practical realities without the need of having to go all the way to the final hearing.

If you are facing an employment dispute, whether that be as an employer or employee, understanding your options early can make a decisive difference in a system where waiting may no longer be viable.
