Uncategorised Employment Law Changes: Why Probation Periods Will Matter More From April 2026

As we have raised in previous articles, UK employment law is changing. From April 2026, a series of reforms will begin to reshape the employer-employee relationship. While much of the discussion focuses on expanding employee protections, there is a clear operational impact for employers, too. One such area is probation periods, and employers need to review how they manage them.

With unfair dismissal protection expected to apply much earlier in employment under forthcoming reforms, employers will need to ensure performance management starts from day one rather than several months in.

For SMEs especially, this means probation periods can no longer be treated as an administrative formality. Instead, they must become structured, actively managed processes.

What is changing?

Currently, employees must usually have two years’ continuous service before they can bring a claim for ordinary unfair dismissal. However, upcoming employment law reforms are expected to significantly reduce this qualifying period. Proposals indicate that this protection could instead apply after around six months of employment. While the exact implementation timeline is still developing, the direction of travel is clear. Employees will gain protections much earlier in their employment, including probation periods. For employers, this reduces the margin for error when hiring and managing new staff.

In practical terms, this means businesses must identify performance or capability concerns much earlier and address them in a structured way.

Why probation periods now carry more risk

Most organisations already use probation periods of between three and six months. We always recommend six months. Traditionally, these have provided a relatively low-risk period to assess suitability for the role. However, if unfair dismissal protection begins much earlier, the timing of these reviews becomes far more important. If concerns about performance, conduct, or capability are not addressed before legal protections apply, employers may face greater risk if issues arise later. This does not mean employers cannot dismiss employees after probation. It does mean decisions must be fair, documented, and supported by evidence much earlier than before.

As a result, employers should view probation periods as a critical risk management stage rather than a routine HR process.

What employers should be doing now

Preparing early will help businesses avoid reactive decisions later. Employers do not need to overhaul their processes overnight, but they should start reviewing how probation periods are managed.

Key steps include:

1. Review probation period length

Many businesses already operate six-month probation periods. However, some may wish to consider whether shorter initial review points would provide better oversight. Introducing formal check-ins at three months, for example, can help identify concerns sooner and allow time for improvement plans if needed.

2. Introduce structured review points

Informal check-ins are no longer enough. Employers should ensure probation reviews happen at planned intervals, such as:

  • 30 days
  • 60 days
  • 70 days
  • 80 days
  • 90 days
  • Final probation review at six months

This creates clear opportunities to address concerns and demonstrate fair management practices.

3. Train managers to have early conversations

One of the biggest risks during probation periods is delayed feedback. Managers often hope that issues will resolve themselves or that they will avoid difficult conversations. However, early and constructive conversations are essential. Managers should feel confident discussing:

  • Performance expectations
  • Areas for improvement
  • Training needs
  • Behavioural concerns

Addressing issues early often leads to better outcomes for both employer and employee. Issues never go away!

4. Document concerns properly

Documentation is often the difference between a defensible decision and a risky one.

Employers should ensure that:

  • Review meetings are recorded on appropriate forms, which are then discussed
  • Concerns are clearly explained
  • Improvement expectations are documented
  • Support provided is noted
  • A summary of what was discussed and agreed upon should be emailed to the employee

Good documentation shows decisions are transparent, reasonable, consistent, and fair.

5. Align contracts and policies

Employment contracts, handbooks, and probation policies should all reflect how probation is actually managed. This may include reviewing:

  • Probation clauses
  • Extension provisions
  • Review processes
  • Notice periods during probation

Ensuring documents match real processes reduces risk and confusion.

Common probation period mistakes to avoid

As employment protections expand, some common habits could create unnecessary risk. Employers should avoid:

  • Leaving reviews too late – waiting until month five to raise concerns gives little time to address issues properly.
  • Treating probation informally – casual conversations are helpful but should not replace formal reviews.
  • Failing to set clear expectations – employees cannot improve if they do not understand what is required.
  • Avoiding difficult conversations – early conversations are usually easier than formal processes later.
  • Assuming probation removes all risk – even during probation, employers must still act reasonably and follow fair processes.

Turning probation into a business advantage

While these changes may seem challenging, they also present an opportunity. A well-managed probation process can improve hiring outcomes and increase retention of strong performers. It allows the early identification of training needs and strengthens management capabilities. It’s also an opportunity to reduce long-term HR risk. Businesses that treat probation as part of their wider people strategy, rather than just a contractual step, often see better workforce stability as a result.

How businesses can prepare with confidence

Employment law is evolving, but preparation does not need to be complex. Small, practical improvements to recruitment, onboarding, and performance management can make a significant difference. Reviewing probation periods and their processes now allows employers to reduce legal exposure while showing support to managers. The trickle-down effect is that the overall employee experience improves, enabling you to build stronger teams. Most importantly, it allows businesses to stay ahead of change rather than reacting under pressure later.
