Major reforms to UK employment law are on the horizon — and they are set to reshape the way employers handle dismissals. As changes to the Employment Rights Bill (ERB) advance through Parliament, businesses and HR leaders must prepare now.
Here is what is changing — and how organisations should adapt.
What’s Changing: A Shift from Two Years to Six Months
Under current UK law, most employees must complete two years of continuous service before they can bring an ordinary unfair dismissal claim.
That is about to change. In late November 2025, the Government announced it was abandoning its plan to grant day-one unfair dismissal protection, instead setting a new six-month qualifying period.
Under the revised rules:
- Employees who complete just six months’ service will gain the right to claim unfair dismissal.
- Existing protections from discrimination, automatic unfair dismissal (e.g. for whistle-blowing or trade union activity) remain effective from day one.
These changes reflect a compromise aimed at balancing worker protection with business flexibility.
Compensation Caps Could Disappear — What That Means
Another significant change under consideration: the Government plans to remove statutory limits on compensation for unfair dismissal.
Under current rules, awards are capped at either 52 weeks of the employee’s gross pay or a fixed statutory amount — whichever is lower.
If the cap is lifted, successful claimants — including high-earners and executives — could receive awards far in excess of current limits. That elevates the financial stakes for employers, and may prompt more cautious — and better documented — dismissal and redundancy procedures.
Implications for Employers: What You Should Do Now
The forthcoming reforms will require many organisations to re-evaluate their HR, recruitment and dismissal practices. Key areas for action:
- Review probation and onboarding practices. With unfair dismissal protection arriving after six months rather than two years, probation periods and performance management processes will need revising. Clear documentation, structured reviews and early performance feedback will be essential.
- Strengthen dismissal and redundancy procedures. Employers should ensure fairness, consistency and compliance — especially if dismissals occur around the six-month mark. Procedural fairness and robust record-keeping will be more critical than ever.
- Reassess risk exposure. Without a compensation cap, claims against high-paid employees could become far more costly. Organisations should evaluate their potential liability and consider whether settlement-oriented approaches or alternative dispute resolution are prudent.
- Communicate and train line managers. Managers must understand the new rules and handle dismissals, performance reviews and misconduct investigations properly. Many employers will likely need updated policies and training to stay compliant.
What Employees Should Know — And What Companies Should Expect
For employees, the changes mean earlier access to protection if they face unfair dismissal. For employers, it signals a new era where the dismissal safety net is broader and the consequences of missteps more significant.
Workers now gain protection after six months, but it remains crucial to distinguish between ordinary unfair dismissal and automatically unfair or discriminatory dismissal — which have always carried day-one protection. Meanwhile, companies should expect higher scrutiny on dismissal decisions, and possibly more claims overall.
As one employment-law consultancy warns, organisations may face a “significant increase in liability” unless they update policies, processes and training ahead of the reforms.
Looking Ahead: What HR Leaders Should Do Before 2026
With the Employment Rights Bill’s provisions likely to take effect in 2026, there is no time to wait. For HR leaders and business owners, the coming months are critical for preparation.
- Audit existing employee contracts, probation terms and dismissal procedures
- Create standardised documentation and decision-making frameworks for dismissal, redundancy, performance and misconduct
- Train managers on fair process, communication, and compliance
- Review severance / exit policies and financial exposure to potential claims
- Consider alternative dispute resolution strategies to mitigate risk
By anticipating what is coming and acting early, organisations can reduce risk, safeguard fairness and ensure that both employer and employee interests are protected under the new regime.
The Bottom Line for HR and Business Leaders
The pending reforms to UK unfair dismissal law mark a significant recalibration of worker protection and employer responsibility. A six-month qualifying period and the possible removal of compensation caps change the stakes, making fairness, clarity and good processes more important than ever.
For UK employers, 2026 will not be business as usual. It will be a test of how well your people strategy, governance structures and dismissal procedures stand up to a new standard of protection and scrutiny.
