With unfair dismissal rights set to kick in after just six months from January 2027, it’s understandable that some employers are questioning whether probation periods still serve a purpose.
After all, if most probation periods last three to six months, hasn’t the window for action effectively closed?
In reality, the opposite is true.
Probation periods have never mattered more than they do now.
The legal landscape is shifting fast
Under the current rules, employees need two years’ service before they can bring an unfair dismissal claim. That timeframe has historically given employers breathing space to correct hiring mistakes with relatively low risk.
From 1 January 2027, that breathing space disappears.
The qualifying period for unfair dismissal will reduce to six months, and the statutory cap on compensation will be removed altogether. That combination significantly raises both the legal and financial exposure of getting early employment decisions wrong.
Importantly, day‑one rights remain unchanged. Claims linked to discrimination, whistleblowing or automatically unfair dismissal don’t require any length of service at all.
Why probation now carries real weight
Previously, probation was often treated as a formality. If someone didn’t quite work out and the process wasn’t perfect, the two‑year qualifying period usually acted as a safety net.
That safety net is going.
Probation is now your only protected window to properly assess suitability, address concerns and make decisive calls before full unfair dismissal rights apply.
Without a clear and well‑managed probation process, employers risk drifting into month six with an underperformer who now has full legal protection. At that point, ending the employment relationship requires a fair reason, a formal process and robust evidence.
A strong probation process helps you avoid that scenario altogether.

What “good” probation looks like in practice
A probation clause alone won’t protect you. What matters is how probation is managed day to day.
An effective probation process should include:
- Clear expectations from day one – including a defined role, early objectives and a realistic learning plan
- Regular, structured review points – not a single conversation at the end
- Timely, specific feedback when concerns arise, recorded in writing
- A genuine chance to improve, with support and training where appropriate
- A formal outcome in writing – confirming pass, extension or termination
This creates an evidence trail that demonstrates fairness, transparency and reasonable decision‑making – all critical if decisions are later challenged.
Rethinking the length of probation
Many organisations default to six‑month probation periods. In the new legal context, that can be a risk rather than a safeguard.
Shortening probation to three months often leads to better outcomes. It forces earlier conversations, sharper decision‑making and prevents issues being deferred until they’re much harder to resolve.
A short, clearly defined extension (for example, one month) can still provide flexibility for borderline cases – without drifting dangerously close to the six‑month threshold.
The goal is simple: decisions about suitability should be made well before unfair dismissal rights come into effect, not at the point they already have.
The hidden risk: unprepared managers
Probation failures are rarely just about the employee.
More often, they stem from managers who avoided difficult conversations, assumed problems would resolve themselves or didn’t appreciate how much the rules had changed.
Without proper guidance, managers can unintentionally expose the business to significant risk – even when intentions are good.
Training managers to handle probation confidently and consistently is just as important as having the right policy on paper.
