What the Employment Rights Act 2025 changes mean for employers

Introduction: Why the Employment Rights Act 2025 changes matter

The Employment Rights Act 2025 brings some of the most significant reforms to UK employment law in recent years. Its provisions promise stronger worker protections, tighter rules for employers and the creation of a new enforcement body. For businesses of all sizes, understanding these changes and preparing now is essential to reduce legal risk and ensure compliant people management.

Main body

Key changes employers need to know

One of the headline reforms is the reduction in the qualifying period for unfair dismissal claims. Under the Act, employees will only need a minimum of six months’ continuous service to bring a claim to the Employment Tribunal, down from the current two years. The reduction is scheduled to take effect on 1 January 2027.

The Act also introduces protections related to industrial action: it will remove the current 12‑week qualifying period for claims arising from termination of employment for taking part in industrial action, widening dismissal protections for those involved in lawful industrial action.

Employers should be aware of a new unfair dismissal ground where dismissal arises because an employee refuses to agree to changes to certain key terms of their employment contract. This protection is subject to a high‑threshold exemption, meaning there are limited circumstances in which employers can rely on it.

Other notable points include proposed changes to statutory sick pay (SSP) and the establishment of a new enforcement body to oversee and enforce parts of the framework. The Act itself runs to over 300 pages and provides a framework for detailed regulations and guidance that will follow.

Timelines and immediate actions

Although many measures are not due to come into force until January 2027, guidance indicates a phased implementation with some changes or preparatory steps relevant in the first half of 2026. Employers are advised to act now: review recruitment procedures, update template contracts and sick pay policies, and ensure managers are trained—particularly during Q2—so processes are consistent before the new rules land.

Conclusion: What this means for readers

The Employment Rights Act 2025 will reshape employer obligations and employee rights. Organisations should triage the key changes, plan mitigation strategies and seek specialist advice as further details and timelines are confirmed. Proactive policy updates, manager training and careful workforce planning will help limit disruption and legal exposure as the new regime is introduced.
