Employment Rights Act 2025:
what leaders actually need to know.
The Act is being overcomplicated. This is a practical summary of confirmed changes, accurate timelines, and what they mean for how you manage people — written for leaders who need clarity, not commentary.
The Employment Rights Act 2025 received Royal Assent on 18 December 2025. It is the most significant overhaul of UK employment law in decades — covering sick pay, family leave, unfair dismissal, fire and rehire, zero hours contracts, flexible working, and enforcement. But it is being implemented in phases, most changes have not yet taken effect, and several widely-reported details are wrong.
This article sets out what has actually changed, what is confirmed for when, and where things are still subject to consultation. It is written for founders, CEOs, and senior leaders — not HR teams. The aim is clarity on what requires action and when.
The businesses that succeed won’t be the ones with the most policies. They’ll be the ones with the clearest thinking.
One important correction upfront: the original Bill proposed making unfair dismissal a day-one right. This was dropped before the Act became law. The qualifying period reduces from two years to six months — but this does not take effect until 1 January 2027. Anyone hired from late June 2026 onwards will gain the protection from that date.
What’s changing — and what isn’t yet.
Eight areas of change. Dates and status confirmed from government and legal sources as of March 2026.
Statutory Sick Pay
From 6 April 2026, SSP is payable from day one of sickness absence — removing the current three-day waiting period. The Lower Earnings Limit is also abolished, meaning lower-paid and variable-hours workers who previously didn’t qualify now will.
Day-one family leave rights
Paternity leave and ordinary unpaid parental leave become day-one rights from 6 April 2026, removing the previous 26-week and one-year service requirements respectively.
Fair Work Agency established
A new statutory enforcement body — the Fair Work Agency — launches in April 2026, consolidating enforcement of SSP, holiday pay, and the National Minimum Wage. Matthew Taylor CBE has been appointed as its first chair.
Collective redundancy awards doubled
The maximum protective award for failure to collectively consult on redundancies doubles from 90 days’ pay to 180 days’ pay. This materially increases the risk of non-compliance with redundancy consultation obligations.
Tribunal time limits extended
Most Employment Tribunal time limits extend from three months to six months, giving employees significantly longer to bring claims from October 2026.
Sexual harassment duty strengthened
Employers must take all reasonable steps to prevent sexual harassment — including harassment by third parties such as customers or clients. NDAs cannot prevent workers from reporting harassment or discrimination.
Unfair dismissal qualifying period
The qualifying period for unfair dismissal reduces from two years to six months, effective for dismissals from 1 January 2027. The cap on unfair dismissal compensation is also removed, allowing unlimited awards. The proposed day-one right was dropped before the Act became law.
Fire & rehire restrictions
Dismissing an employee for refusing changes to core contractual terms — pay, hours, holiday, pension — will become automatically unfair in most cases. A narrow financial hardship exception applies. This was originally expected in October 2026 but has been pushed to January 2027.
When things happen — in plain terms.
The Act is phased across 2026 and 2027. Most changes have not yet taken effect. Here is the confirmed sequence.
Plain terms. No HR theatre.
SSP from day one and day-one family leave rights are confirmed and close. Review your sickness absence policies, payroll systems, and employment contracts before 6 April 2026.
Anyone you hire from late June 2026 onwards will have unfair dismissal protection from January. Your probation processes, performance management, and dismissal procedures need to be robust before then — not after.
The doubling of protective award maximums from April 2026 means getting collective redundancy consultation wrong is now substantially more expensive. If you are planning any restructuring, the process matters more than it did.
Extended tribunal time limits mean you are exposed for longer after any dismissal or dispute. Records of decisions, processes followed, and conversations held need to be thorough and contemporaneous.
The guaranteed hours rights are not in force yet and are still subject to consultation. If you use zero-hours or variable-hours arrangements, start auditing them now — but decisions can wait for confirmed detail.
People decisions now carry more weight, earlier, and with less room for error.
The Employment Rights Act isn’t a problem to solve. It’s a signal — that the cost and consequence of poor people decisions is increasing. The businesses that handle this well won’t be the ones with the most updated policy documents. They’ll be the ones with clear thinking and sound processes.
