The Employment Rights Act, which received Royal Assent on 18 December 2025, has been described as the biggest upgrade to workers’ rights for a generation. Coming from the Labour Government’s manifesto pledge to ‘Make Work Pay’, it sets out the most ambitious set of employment related reforms for over half a century. Among some of the most significant changes, the Act will reduce the two-year qualifying period for ordinary unfair dismissal claims to six months and remove the cap on the compensatory award for unfair dismissal, broaden the right to statutory sick pay, enhance protections for workers on zero hours contracts, ban fire and rehire processes in most circumstances and make sweeping changes to trade union rights.
The Act was the subject of extensive debate and amendment throughout its parliamentary passage until the House of Lords finally gave way to amendments by the House of Commons following a number of concessions.
On 1 July 2025 the Government published an Employment Rights Bill Implementation Roadmap setting out its anticipated commencement dates for the various changes under the legislation. The Roadmap sets out a phased approach to implementing the changes over the next two years. For more information on the anticipated timings of the various changes, see our Employment Rights Act timeline.
The key changes for employers to be aware of are outlined below.
