Probation in Practice: Preparing for the Unfair Dismissal Changes

Employers keep asking me about the upcoming changes to unfair dismissal rights. It’s clearly a big concern, and they’re right to start thinking now — tightening processes early will prevent being caught out later.

From 1st January 2027:

• Unfair dismissal protection will reduce from two years to six months.

• The statutory compensation cap will be removed.

This fundamentally affects how probation is managed and how organisations handle short-service employees moving forward.

Probation: Policy vs Reality

Probation policies often look structured: 3–6 months with scheduled reviews. In practice, it’s often very different:

• Manager-led, informal, and influenced by operational pressures

• Reviews delayed or poorly documented

• HR usually involved only when dismissal is likely

The gap between policy and reality creates risk. Strong evidence and documentation standards will be essential to ensure fair and defensible decisions.

To adapt to the new legal environment, organisations are likely to:

• Introduce more checkpoints during probation

• Run more structured review meetings

• Provide earlier feedback and review cycles

• Monitor performance and capability more closely

  
  

These changes will make probation more formal and scrutinised but also safer and fairer for both employees and employers.

Who Gains Rights and When

The new “six-month rule” means:

• Employees with six months’ service on 1st Jan 2027 automatically gain unfair dismissal rights

• Staff under two years’ service today will suddenly gain protection at that point

• New hires after 1st July 2026 only qualify once they reach six months

• Leaving dismissals very close to 1st Jan 2027 could create legal exposure due to statutory notice rules

Review and manage current short-service staff now.

Why Employees Leave During Probation

Most early exits result from one or a combination of the following:

• Performance gaps

• Attendance concerns

• Conduct issues

Managing Probation Fairly

A defensible probation process includes:

• Clear expectations from day one

• Scheduled review meetings with documented feedback

• Robust evidence of performance, behaviour, and support offered

• Opportunity for employees to respond

• Evidence-based decisions

• Consistency across teams

Informal feedback is fine, but strong documentation and evidence standards protect both the employee and the organisation under the new rules.

Decisions often rely heavily on manager judgment, but gaps in documentation increase legal risk. Structured, evidence-based reviews ensure employees have the opportunity to respond, and help safeguard both employee and organisation. Probation dismissals are likely to face greater scrutiny from HR, lawyers, and Employment Tribunals, making clear evidence and employee voice essential.

Preparing for the Legal Changes

To adapt to the new rules:

✔️ Review and update probation policies

✔️ Strengthen documentation and evidence standards

✔️ Assess manager capability and train them to handle early performance concerns proactively

✔️ Review and update dismissal processes to ensure fairness and compliance

✔️ Consider shortening probation periods for new starters

Preparation is the key to reducing risk.

Wider Organisational Impacts

The changes affect more than individual cases and could result in the following:

• More cautious hiring decisions to avoid future risk

• Increased HR oversight

• Potential increase in fixed-term contracts

• Consistency challenges: manager capability varies, operational pressures remain, evidence/documentation is often inconsistent, and different teams may approach probation differently

Unintended consequences may include:

• More defensive HR practices

• Earlier dismissals

• Heavier admin and HR involvement

• Higher training costs

• Increased Employment Tribunal claims and associated costs

• Reputational damage

• More settlement agreements

Addressing these risks requires robust policies, strong evidence/documentation, structured processes, and training for managers.

Conclusion

Probation will inevitably become more formal and scrutinised. Employers who act now — updating policies, documenting feedback, training managers, and strengthening evidence standards — will reduce risk, improve employee experience, and strengthen trust.

Start today: your current and future hires, and your organisation’s legal and reputational standing will thank you.
