Employment law in the UK is evolving, and for SMEs, one of the most significant upcoming changes is the expected reform to unfair dismissal rights.

For years, many small businesses have operated with a degree of flexibility during the early stages of employment, particularly within probation periods. But with proposed changes expected to come into effect in 2027, that landscape is shifting.

Put simply, employers will need to be more structured, more consistent and more evidence-based from the very start of the employment relationship, and this requires some preparation.

What’s changing?

While final details are still being confirmed, the direction of travel is clear. The proposed changes aim to strengthen employee protections earlier in employment, reducing the traditional qualifying period currently required to bring an unfair dismissal claim.

This means employees may gain the right to challenge dismissal much sooner than before, potentially from day one or after a significantly shorter period of service.

For SMEs, this represents a fundamental shift.

The assumption that early-stage employment carries lower legal risk will no longer hold in the same way. Decisions made in the first few months of employment will need to stand up to greater scrutiny.

Why this matters for SMEs

In large organisations, structured HR processes are often already in place, but in SMEs, people management can be more informal, and that’s where the risk lies.

Many small businesses rely on trust, instinct and quick decision-making. While these are strengths, they can become vulnerabilities when legal expectations increase.

If dismissal decisions are made without clear documentation, consistent processes or evidence of fairness, the risk of challenge increases.

For SMEs, a single claim can have a disproportionate impact, financially, operationally and emotionally.

The end of “informal probation”

One of the biggest shifts will be how probation periods are managed.

Probation will still exist, but it will no longer act as a safety net in the way some employers have relied on historically. The idea that you can simply “let someone go” during probation without a structured process is becoming increasingly risky.

Instead, employers will need to demonstrate that:

• Expectations were clearly communicated
• Performance or conduct concerns were raised promptly
• The employee was given an opportunity to respond and improve
• Decisions were reasonable and evidence-based

In practice, this means probation periods need to be actively managed, not just noted in a contract.

Performance management starts from day one

With earlier access to unfair dismissal rights, the first few weeks of employment become more important than ever.

Clear onboarding, defined objectives and regular check-ins are part of risk management.

Employees should understand what success looks like in their role from the outset. Managers should be having structured conversations about progress, challenges and expectations.

If issues arise, they need to be addressed early, clearly and constructively.

This approach benefits both sides. It gives employees the best chance to succeed, and it provides the business with a clear record of support and communication.

Documentation will become essential

One of the most common challenges SMEs face in employment disputes is lack of documentation.

Even when managers have had conversations or raised concerns, if those discussions aren’t recorded, they are difficult to evidence later.

Under the new landscape, documentation doesn’t need to be complex, but it does need to exist.

Simple records of probation reviews, feedback conversations and agreed actions can make a significant difference. They demonstrate fairness, consistency and transparency.

Without this, decisions can appear arbitrary, even when they are not.

Consistency across the business

As expectations increase, consistency becomes critical.

If similar situations are handled differently across the business, it creates risk. Employees may perceive unfair treatment, even if the intention was reasonable.

Having clear policies and ensuring managers apply them consistently helps reduce this risk. It also builds trust within the team.

Consistency means following the same principles and processes in a fair and balanced way.

Supporting managers to get it right

In SMEs, much of the responsibility for managing people sits with line managers, many of whom have had little formal HR training.

As expectations around fairness and process increase, manager confidence becomes even more important.

Managers need to feel comfortable:

• Having honest performance conversations
• Giving clear, constructive feedback
• Following structured processes
• Escalating issues when needed

Without this support, businesses are more likely to fall back into informal practices that increase risk.

A shift towards proactive HR

The changes to unfair dismissal are part of a wider trend.

Employment law is moving towards greater protection, earlier rights and higher expectations on employers to act fairly and transparently.

For SMEs, this means moving from reactive HR to proactive HR.

Instead of dealing with issues when they arise, businesses need to build strong foundations. Clear contracts, effective onboarding, structured probation, and confident management.

What SMEs should be doing now

You don’t need to wait until 2027 to act.

Now is the time to review how your business manages new starters and early-stage employment. Consider whether expectations are clearly set, whether managers are supported, and whether key conversations are documented.

Look at your probation processes.

Are they structured?

Are review points built in?

Are decisions explained and recorded?

Small improvements now will make a significant difference when the changes come into effect.

The upcoming changes to unfair dismissal represent a shift in how employment relationships are managed from day one.

For SMEs, this is about creating clarity, fairness and confidence in how people are managed.

Businesses that prepare early will not only reduce risk, they will also build stronger, more engaged teams.

Those that rely on informal approaches may find the transition more challenging.
