What has changed in the employment tribunal system?
The way tribunal claims are handled has modernised significantly. Most processes are now digital, with employers submitting ET3 responses online through MyHMCTS. The 28-day deadline to respond remains strict and begins from the date the tribunal sends the claim.
Hearings increasingly take place remotely, which can reduce travel time but requires careful preparation to ensure witnesses and representatives are confident with the technology. Updated Employment Tribunal Procedure Rules (2024) now govern how cases are managed, including clearer provisions for costs and deposit orders.
Despite digital improvements, caseloads remain high. More than 40,000 single claims were received in the past year, with many still awaiting final hearings. This delay can shape strategy, influencing whether early settlement may be more effective than a lengthy defence.
What are the most common type of employment tribunal claims?
The main types of claims remain consistent: unfair dismissal, discrimination, whistleblowing and breach of contract.
Hybrid working has brought disagreements over attendance expectations and flexible working requests. Data protection issues are also surfacing, particularly where employee monitoring or biometrics are introduced without sufficient privacy assessments. Meanwhile, some businesses are seeing challenges linked to the use of artificial intelligence in recruitment or performance management decisions.
Each of these trends highlights the importance of up to date policies and transparent communication. A well-drafted hybrid working policy, clear data monitoring notices and regular training on equality obligations can reduce the risk of claims arising or, if they are raised, of succeeding. For further guidance, see our article on avoiding discrimination in the workplace.
Understanding the role of ACAS Early Conciliation in employment tribunals
Before a claim reaches the tribunal, employees must go through ACAS Early Conciliation in the majority of cases. This stage is designed to help both sides explore settlement before proceedings begin.
When ACAS becomes involved, a conciliator will contact you to discuss whether the matter can be resolved informally. Time limits are paused during this stage, and the parties receive an Early Conciliation certificate once it ends. The process can last up to twelve weeks, although if one party declines to engage, or if it becomes clear that a resolution is not going to happen, it can close earlier than that.
For employers, this is often the most cost-effective moment to reach agreement. ACAS data shows that most potential claims do not proceed beyond conciliation. Engaging constructively at this point can save time, costs and the stress of formal litigation. Tactically, some employers make a conscious decision not to engage with early conciliation and adopt a ‘wait and see’ approach, to see if the employee does decide to bring a claim. If they do, settlement can still be achieved via ACAS although there is a risk that the claimant may be less receptive to it by then, particularly if they’ve had to take the time and incur the cost of instructing their own solicitor.
Responding to an ET1
Receiving an ET1 can feel unsettling, but early organisation makes all the difference. As soon as the claim arrives, note the date it was sent and calculate your 28-day deadline to file the ET3 response.
Read the claim carefully, preserve all relevant evidence, and appoint a lead contact within your organisation to coordinate communications. If you have employment practices liability insurance, inform your insurer immediately to check whether panel solicitors are required.
The ET3 response must be submitted online through MyHMCTS. Once filed, the tribunal will confirm next steps, which may include a preliminary hearing to set directions for evidence and disclosure. Obtaining legal advice at this stage helps you identify the strengths and weaknesses of your case and plan your approach effectively.
How to respond to an employment tribunal claim
Tribunal cases usually follow a standard path. After the ET1 and ET3 are exchanged, a timetable is set so that the parties can prepare for the final hearing. In complex claims such as discrimination or whistleblowing, the tribunal will list a case management hearing to consider the issues in more detail. These usually take place by video.
The first stage in the timetable is to exchange relevant documents with the other side, after which a hearing bundle is prepared (usually by the respondent) and then witness statements are prepared and exchanged.
Witness statements serve as the witness’s main evidence and are read by the tribunal in advance. Hearings are increasingly hybrid or fully remote, and both parties must be ready to share digital documents quickly and clearly.
Meticulous organisation at this stage demonstrates professionalism and credibility, which is always of assistance to the tribunal and to how the parties come across.
How digital hearings and backlogs affect employment tribunals
The move to online systems has streamlined administration but not necessarily speed. Tribunals continue to face significant backlogs, meaning it can take many months or even years before a case is listed for hearing.
This delay has strategic consequences. Some employers use the time to explore settlement options, while others treat the pause as an opportunity to strengthen evidence or address systemic issues within the business.
Where hearings are remote, preparation is required. Test your technology in advance, check that witnesses have a quiet space to participate and remind them to speak slowly and clearly. Effective presentation, even through a screen, can have a real impact. Keep in mind too that the same rules apply as if the witness was giving evidence in the tribunal building: they can’t discuss their evidence whilst they are under oath, they must only have an unmarked copy of their witness statement and the hearing bundle in front of them whilst they give evidence and no one can assist them whilst they are giving their evidence. There can be serious consequences if those rules are breached.
Financial and reputational implications of an employment tribunal
Tribunal proceedings and outcomes can be costly. At the moment, compensation for unfair dismissal claims can be up to 52 weeks’ gross wages. This is subject to an overall cap of £123,543. In relation to any unfair dismissal where the effective date of termination is on or after 1 January 2027, that cap is removed altogether. In discrimination cases, compensation for injury to feelings is awarded using the Vento bands, which increased again in April 2026. The middle band now ranges up to £37,700 while serious cases can exceed £62,900.
Although tribunals rarely order one party to pay the other’s legal fees, costs and deposit orders can be made where a party acts unreasonably. Employers can also face a separate penalty of up to £20,000 for aggravated breaches of workers’ rights.
Beyond financial exposure, the reputational risks are significant. Judgments are published online, making disputes visible to clients, employees, future hires and the media. For businesses who work in the public procurement field, findings of discrimination often have to be disclosed as part of the procurement process, which can damage attempts to secure future contracts. A proactive communication plan and consistent messaging will help protect your brand throughout the process.

Common employment tribunal pitfalls to avoid
Many employers underestimate how strict tribunal timelines are. Missing the 28-day ET3 deadline can result in a default judgment that is difficult to overturn. Weak record-keeping is another recurring issue. Inconsistent notes, missing policies or incomplete disciplinary records can undermine even the strongest defence.
Data and privacy are also becoming flashpoints. If your business monitors staff activity or collects biometric information, ensure you have carried out a data protection impact assessment and informed employees clearly about what data is collected and why. Keep in mind too that from 19 June 2026, there is an obligation upon employers to deal with data protection complaints made by employees.
Finally, avoid fragmented internal communication. Disagreements between managers or inconsistent accounts can damage credibility in front of a tribunal judge. Such communications are discloseable in any litigation including tribunal proceedings, so employers may be faced with the need to explain those disagreements or inconsistencies.
How to prepare your organisation for employment tribunal law changes
The best way to minimise tribunal risk is through prevention. Review employment contracts, policies and training regularly to ensure they reflect current law and your working practices.
Invest in management training that covers fair process, equality and note-taking. Revisit flexible working and hybrid arrangements to confirm they are applied consistently and transparently.
The Employment Rights Act 2025 will extend most tribunal time limits to six months (likely from October 2026) and will reduce the qualifying period of employment from two years to six months from 1 January 2027, meaning that a much wider group of individuals will be able to bring unfair dismissal claims. Changes have already been introduced in relation to family-related leave, so employers should familiarise themselves with those if they are not already aware of them. If redundancies or restructuring are planned, our redundancy process guide explains how to manage changes lawfully and fairly.
