Employment Law Updates 2026 - Why Employers Must Rethink Probation & Performance Management Now

The Employment Law Updates 2026 that Every Employer Must Prepare For

As we approach a significant shift in UK employment legislation, many employers are still operating under assumptions that will soon be out of date. The employment law updates 2026 will not just tweak existing processes. They will fundamentally change how businesses manage probation periods, performance concerns and dismissal risk.

For CEOs, HR managers and business owners, this is not a distant legal development. It is something that requires preparation now.

The Employment Rights Act 2025 is introducing one of the most substantial changes to unfair dismissal rights in decades. If your organisation relies on traditional probation periods as a safety net, it is time to revisit that strategy.

The Six-Month Threshold: A Major Shift in Unfair Dismissal Rights

Currently, employees need two years of continuous service to bring a claim for ordinary unfair dismissal. From January 2027, that qualifying period will reduce to six months.

This creates a clear legal milestone at the six-month mark. Once an employee reaches that point, they will gain the right to claim unfair dismissal. In practical terms, this significantly reduces the window in which employers can assess suitability without facing the risk of a full unfair dismissal claim.

For many organisations, probation periods are typically set at three or six months. Under the new framework, if performance concerns are not identified, documented and addressed early, employers may find themselves managing complex dismissal procedures much sooner than anticipated.

There is also an additional financial consideration. The statutory cap on unfair dismissal compensation is set to be removed in 2027. This increases potential financial exposure where dismissals are mishandled. A poorly managed probation process will no longer carry relatively limited risk.

These employment law updates 2026 require a proactive approach. Waiting until 2027 will be too late.

Dismissal during Probation Is Not a Litigation Free Zone

One of the most common misconceptions we encounter is that employees have very few rights during probation. That has never been correct, and it will become even more risky to rely on that assumption moving forward.  

Regardless of length of service, employees are protected from day one in several important areas:

• Protection from discrimination under the Equality Act 2010, including age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex and sexual orientation
• Protection for whistleblowing where an employee makes a protected disclosure
• Statutory rights such as entitlement to minimum notice, holiday pay and the national minimum wage

These rights already apply during the probation period. The reduction in the unfair dismissal qualifying period simply narrows the gap between day one protections and unfair dismissal rights.

Employers must therefore treat probation as a structured and legally managed process rather than an informal trial period.

Rethinking Performance Management Before Month Six

Under the employment law updates 2026, performance management can no longer be reactive. It must begin early and be clearly documented.

Too often, issues are left unaddressed until the end of a probation period. Managers may hope that performance will improve naturally or feel uncomfortable raising concerns. Under the new framework, this approach carries significant risk.

Performance management should be viewed as an ongoing cycle from the first weeks of employment. Clear expectations must be set at the outset. If an employee does not understand what success looks like, it will be difficult to justify any decision to terminate their employment.

There are several essential steps every employer should be taking:

• Define clear written KPIs and performance standards at the start of employment
• Hold regular documented one-to-one meetings during the first three months
• Address concerns as soon as they arise rather than waiting for a formal review point
• Keep written records of discussions, action plans and agreed improvements

From a legal perspective, documentation is critical. In tribunal proceedings, written evidence will carry far more weight than recollections of informal conversations. If performance concerns are not recorded, it becomes much harder to demonstrate fairness.

Under the six-month qualifying period, employers cannot afford to delay difficult conversations until month five. Early intervention is now a core risk management strategy.

Extending Probation - Proceed with Care

Many contracts allow for the extension of a probation period where performance is close to the required standard. While extensions remain lawful if permitted by the employment contract, their strategic value is changing.

If a probation period is extended beyond six months, the employee will still gain ordinary unfair dismissal protection once they cross that statutory threshold. Extending probation will no longer provide protection from tribunal claims once six months of service has been reached.

This means employers must think carefully before relying on extensions as a solution. An extension may still be appropriate in some circumstances, but it should not be viewed as a way to delay difficult decisions beyond the new legal deadline.

Contracts and handbooks should be reviewed now to ensure they accurately reflect how probation and extensions will operate under the new regime.

Why Acting Now Matters

The employment law updates 2026 are not simply about legal compliance. They are about organisational culture, leadership and accountability.

Businesses that manage probation and performance well are more likely to retain strong employees and address underperformance constructively. Those that rely on informal processes or delayed decision making may find themselves exposed to costly disputes.

Reviewing policies now provides breathing space. It allows time to train managers, update documentation and embed consistent procedures across departments.

Our Business Employment team is already working with employers to prepare for these changes. This includes reviewing contracts of employment, auditing probation clauses, updating staff handbooks and advising on practical performance management frameworks.

Preparing Your Business for the 2026 Employment Law Changes

If you are a CEO, HR director or business owner, now is the time to ask:

• Are our probation processes structured and documented?
• Are managers trained to address performance issues early?
• Do our contracts allow for lawful and strategic probation extensions?
• Are we prepared for the removal of the unfair dismissal compensation cap?

Answering these questions now will reduce risk significantly in 2027.

We offer ongoing HR support through our myHR Service, acting as an external HR and legal partner for businesses that want real time advice on employee relations matters. Our 24 Month HR and Policy Guarantee also ensures that your documentation remains legally compliant as legislative changes take effect.
