Every Retail Hire From 1 July Can Claim Unfair Dismissal in Six Months

From 1 July 2026, the qualifying period for ordinary unfair dismissal drops from two years to six months. For retailers — who hire heavily for summer, back-to-school and Christmas — that single change quietly rewrites the risk on every new contract you sign from July onwards.

A seasonal sales assistant taken on in July 2026 will be able to bring an unfair dismissal claim from January 2027, while they are still on your books. Most shop owners have not budgeted for this. This guide explains what is changing, why retail is unusually exposed, and the practical steps to take before the summer hiring rush.

What Is Changing — and When

Under the Employment Rights Act 2025, the period an employee must work before they can claim ordinary unfair dismissal falls from two years to six months, with effect from 1 July 2026. The right is not quite "day one" — a short qualifying period remains — but in practice it means almost any worker who stays past their probation can challenge a dismissal at an employment tribunal.

Crucially, the change applies to new and existing staff alike. Anyone who has six months' service on or after 1 July 2026 is in scope. For a retailer with steady turnover, that is most of your team within weeks of the change.

Why Retail Is Especially Exposed

Retail runs on flexible, seasonal labour: summer cover, students, Christmas temps, and a higher-than-average rate of staff churn. Historically, the two-year qualifying period meant most of these shorter-tenure workers could be let go with little legal risk. From July 2026 that protection for employers largely disappears.

The businesses most affected are those that hire in waves and review performance informally — exactly the pattern in shops, supermarkets, garden centres and hospitality-retail. If you take on ten summer staff and part ways with three because "it did not work out," each of those three could, after six months, argue the dismissal was unfair unless you followed a fair process.

What Unfair Dismissal Actually Means

Unfair dismissal is not about whether you had a reason — it is about whether the reason was one the law recognises (conduct, capability, redundancy, legal restriction, or "some other substantial reason") and whether you followed a fair procedure. A dismissal can be substantively justified but still ruled unfair because the process was rushed or undocumented.

For retail managers, the practical takeaway is that "letting someone go" on a manager's say-so, without warnings, evidence or a chance to improve, is the kind of decision that becomes risky once the six-month threshold is crossed.

What It Can Cost You

A successful unfair dismissal claim has two parts: a basic award (calculated like statutory redundancy, on age, length of service and weekly pay) and a compensatory award for lost earnings. From April 2026 the maximum compensatory award rose to £123,543, or 52 weeks' gross pay if lower. Dismissals tied to discrimination, whistleblowing or health and safety are uncapped.

Even where awards are modest, the cost of defending a claim — management time, legal fees and the risk of a tribunal hearing — typically dwarfs the price of getting the process right in the first place.

What to Do Before 1 July

You do not need to stop hiring seasonal staff. You need to make your processes defensible:

• Use a real probation period. Set a clear probation (e.g. up to three or six months), with documented review points, so capability concerns are raised and recorded early.
• Write things down. Keep brief notes of performance conversations, training given, and any warnings. Tribunals reward employers who can show a paper trail.
• Follow a fair process. For conduct or capability, that means raising the issue, giving a chance to improve, and holding a meeting before any dismissal.
• Issue compliant contracts. Every worker is entitled to a written statement of terms from day one — make sure your seasonal contracts are in order.
• Train your managers. The biggest risk is a well-meaning store manager dismissing someone informally. A short briefing now prevents an expensive claim later.

Frequently Asked Questions

Does this affect staff hired before July 2026? Yes. Once an employee reaches six months' service on or after 1 July 2026, they are protected, regardless of when they started.

Can I still use probation periods? Yes, and you should. Probation does not remove unfair dismissal rights once the qualifying period is met, but a properly run probation gives you a fair, documented basis for ending employment that is not working out.

Are there dismissals that were always protected from day one? Yes — dismissals for reasons such as pregnancy, trade union membership, whistleblowing or asserting a statutory right have never required a qualifying period. The July 2026 change widens protection for ordinary unfair dismissal.

Key Takeaways

• From 1 July 2026, ordinary unfair dismissal rights begin at six months' service, not two years.
• Retailers who hire seasonal and high-turnover staff are among the most exposed.
• The fix is process: real probation reviews, written records, fair procedures and trained managers.
