Many employers are familiar with the current employment tribunal time limits. In most cases, employees have three months less one day to bring a claim following an incident such as dismissal, discrimination or unlawful deduction of wages.
Under the Employment Rights Act 2025, that position is set to change. The Government plans to extend the time limit for many employment tribunal claims from three months to six months, giving employees significantly longer to pursue legal action. While this may seem like a procedural change, the impact on employers could be substantial. For businesses, longer claim periods mean longer legal exposure, greater importance of workplace documentation and an increased need for effective people management practices.
In this guide, we explain what is changing, why it matters and how employers can prepare.
An employment tribunal is an independent legal body that resolves disputes between employers and employees. Tribunals hear cases involving a wide range of workplace issues, including:
Unfair dismissal
Discrimination
Harassment
Unpaid wages
Breach of contract
Whistleblowing
Working time disputes
Employment tribunals play a key role in enforcing workplace rights and providing remedies where legal obligations have not been met.
Currently, most employment tribunal claims must be submitted within three months less one day of the relevant incident. For example, if an employee is dismissed on 1 January, they would generally have until 31 March to begin the tribunal process, subject to ACAS Early Conciliation rules. Many employers view this period as a key point after which the likelihood of legal action begins to reduce.
The Government intends to extend the time limit for many employment tribunal claims from three months to six months. The proposed change is expected to take effect during 2026 as part of the wider Employment Rights Act implementation programme. The aim is to provide employees with additional time to seek advice, gather evidence and consider their options before commencing legal proceedings. For employers, however, this means workplace disputes may remain "live" for considerably longer.
The Government has stated that some employees struggle to access advice and support within the current three-month period. Extending the deadline is intended to improve access to justice and ensure workers have a reasonable opportunity to pursue legitimate claims. The change aligns with broader reforms designed to strengthen workplace protections and employment rights.
The most significant impact is likely to be increased legal exposure. Issues that might previously have been considered resolved after a few months may now remain potential tribunal risks for much longer. Employers may need to retain records for longer periods, conduct more robust investigations and ensure managers document workplace decisions effectively.
The extension also reinforces the importance of maintaining accurate records relating to:
Disciplinary actions
Grievances
Performance management
Workplace investigations
Absence management
Harassment complaints
Employee communications
Strong documentation can be critical if an employer needs to defend a tribunal claim months after an incident occurred.
Many tribunal cases are won or lost based on evidence rather than intention. Managers may leave the business, memories fade and details can become difficult to verify over time. Clear documentation provides an accurate record of events and demonstrates that decisions were made fairly and consistently. As claim periods increase, employers should review their document retention practices and ensure important records can be accessed when needed.
While all employers should prepare for the changes, some sectors may face greater exposure due to workforce size, employee turnover or operational complexity.
This may include:
Construction
Warehousing and logistics
Security services
Manufacturing
Retail
Hospitality
Care services
Employers in these sectors often manage large workforces and may encounter a higher volume of employee relations issues.
Preparation should begin before the new rules come into force. Employers should review workplace procedures and ensure managers understand the importance of accurate record keeping.
Areas to consider include:
Investigation procedures
Disciplinary processes
Grievance handling
Employment contracts
Workplace policies
Manager training
Compliance audits
Organisations that invest in strong people management processes are likely to be better positioned to manage future employment disputes.
Employment tribunal claims often arise from management decisions, communication failures or procedural mistakes.
