The Employment Rights Act 2025 is due to receive Royal Assent on 18 December 2025 and represents one of the most significant reforms to UK employment law in recent years. The Act introduces wide-ranging new worker protections, including the expansion of unfair dismissal rights, changes to Employment Tribunal time limits, broader access to family leave, and enhanced protections against harassment and discrimination. These reforms will have direct and lasting implications for employers’ policies, procedures, and workforce management.

Most of the Act’s key provisions will be introduced in stages over the next two years, making early awareness and forward planning essential. In this practical guide, we set out the anticipated implementation timetable and identify what actions employers need to take – and when – to ensure compliance, minimise risk, and adapt to the new regulatory landscape.
