Unfair Dismissal Law Changes 2027: Why Probation Management Matters More Than Ever

Effective Probation Period Management will be increasingly important for employers as, from 1 January 2027, employees will be able to bring an unfair dismissal claim after just six months’ service, down from two years, and the cap on compensation is being removed. Much of the discussion has focused on legal risk. The more practical question is whether your managers are equipped to spot and address performance concerns early enough to make informed decisions before that protection kicks in.

For many employers, the discussion has focused on legal risk and employment documentation.

However, the more important question may be a practical one: are your managers equipped to identify, address and manage performance concerns early enough to make informed decisions before unfair dismissal protection applies?

For many businesses, particularly smaller and growing organisations, probation period management has traditionally been treated as relatively informal.

A new employee joins, settles into the role and a review takes place towards the end of their probationary period. The reduction in the qualifying period for unfair dismissal means that approach may no longer provide employers with sufficient time to assess suitability and address concerns before statutory protection applies.

Performance management starts long before there is a problem

One of the most common misconceptions is that performance management begins when an employee starts underperforming. In reality, effective performance management starts from the first day of employment.

A well-managed probation period should provide employers with an opportunity to assess capability and suitability for the role, whilst ensuring employees receive appropriate support, training and feedback to help them succeed.

ACAS guidance emphasises the importance of setting clear expectations from the outset, integrating probation into wider performance management arrangements and conducting regular review discussions throughout the probationary period. Employees should understand what is expected of them, how their performance will be assessed and what successful completion of probation looks like. Establishing those expectations early can help provide a clear framework for performance discussions should concerns arise later.

Why probation periods now carry greater significance

The practical reality of the new unfair dismissal regime is that employers will have less time available to assess whether a new employee is right for the role. Whilst probation periods remain contractual rather than statutory, they are likely to become increasingly important in helping employers make informed decisions about ongoing employment.

A probation period supported by regular review meetings, meaningful feedback and timely intervention provides a greater opportunity to identify concerns whilst they remain capable of being addressed. In many cases, issues raised promptly can be managed through additional support, coaching, clearer objectives or further training before they become more significant problems.

Probation is not a free pass

The forthcoming changes should not obscure an important point: probation periods have never provided complete freedom to dismiss employees without risk.

Employees have long enjoyed protection against unlawful discrimination, harassment and victimisation from the commencement of employment. Certain dismissals may also be automatically unfair regardless of service length, including dismissals connected to whistleblowing, health and safety activities and trade union rights. The importance of handling probation fairly therefore extends well beyond ordinary unfair dismissal rights.

The reduction in the qualifying period simply means that employers are now likely to face greater scrutiny of decisions affecting employees much earlier in the employment relationship.

The importance of feedback, support and documentation

One of the difficulties employers frequently encounter is the absence of any meaningful record of performance discussions. Managers may have genuine concerns regarding capability or conduct, but those concerns have never been clearly articulated or documented during employment.

Good performance management does not require excessive bureaucracy. In many cases, brief written records of review meetings, objectives, feedback provided and actions agreed will be sufficient. What matters is that both parties understand what has been discussed and what is expected moving forward.

Equally important is the question of support. Employers should consider whether concerns may be resolved through additional training, clarification of expectations, coaching or other workplace support. A fair approach to performance management is rarely limited to identifying shortcomings; it also involves providing employees with a reasonable opportunity to improve.

When an extension may be appropriate

Not every probation period concludes with a clear decision to confirm employment or terminate it. In some cases, employers may reasonably conclude that additional time is required before a final decision can be made.

Where this occurs, an extension to probation may provide a sensible solution, particularly where there are signs of potential but further evidence is required.

Employers should ensure that any right to extend probation is clearly set out within the employment contract and that employees understand the reasons for the extension, the standards expected moving forward and the possible outcomes if improvement is not achieved.

An extension should not be used simply to postpone a difficult decision, but where applied properly it can provide valuable additional time for both employer and employee.

What should employers be doing now?

As the 2027 reforms approach, employers should consider whether their existing probation period management arrangements remain fit for purpose. In particular, businesses may wish to review:

  • Employment contracts and probation clauses.
  • Any contractual right to extend probation.
  • Onboarding and induction practices.
  • Performance review arrangements during probation.
  • Manager capability and training.
  • Staff handbooks and performance management procedures.
  • Processes for recording probation discussions and outcomes.

These changes are not about creating unnecessary formality or introducing burdensome procedures. Rather, they are about ensuring managers have the tools and confidence needed to make fair, informed and defensible decisions regarding employee performance.

Probation Period Management – The bigger picture

The reduction in the unfair dismissal qualifying period is likely to encourage a greater focus on effective people management from the earliest stages of employment.

Businesses that already set clear expectations, provide regular feedback and address concerns promptly are unlikely to require significant change. Those relying on informal or inconsistent probation arrangements may wish to review their approach before the new regime takes effect.

Ultimately, effective performance management is not simply about avoiding claims. It is about creating an environment in which both employers and employees have the greatest possible opportunity to succeed.
