Dismissal during probation (2026): Rights, notice, and unfair dismissal risks

Dismissal during probation doesn’t remove your legal rights. Probation offers employers flexibility, but it doesn’t suspend discrimination protection, whistleblowing rights, or family leave. In such scenarios, you may be able to bring a claim immediately, regardless of probation length, depending on the facts. But remember, time limits are strict; typically three months from dismissal. Consult an employment solicitor promptly if your probationary dismissal followed a protected complaint, as delay can materially weaken your claim.

Continue reading to understand which probationary dismissals are legally challengeable and when action is essential.

Unfair dismissal during probation: The two-year threshold and automatic exceptions

Unfair dismissal during probation period claims are blocked by a two-year service requirement, unless your dismissal involved a protected reason. Most employees cannot claim unfair dismissal before completing two years of continuous employment, even if the process was flawed or the decision harsh.

However, automatically unfair reasons bypass this barrier entirely. If your dismissal involved whistleblowing, discrimination, statutory right assertion, or related protected grounds, you may be able to bring a claim immediately, regardless of probation length, depending on the circumstances.

• Automatically unfair reasons: protected disclosure (whistleblowing), trade union activity, statutory right assertion (flexible working, maternity leave, jury service), health and safety complaints, working time enforcement, family leave participation.
• Procedural defects alone (no investigation, no hearing, no appeal) do not trigger unfair dismissal during probation unless the reason itself is automatically unfair.
• The burden to prove the dismissal reason rests with the employer at tribunal.
• Request written confirmation of the dismissal reason immediately to establish whether an exception applies.

Protected grounds during probation: Discrimination, whistleblowing & statutory rights

Dismissal during probation for discrimination, whistleblowing, or statutory right assertion is immediately actionable regardless of employment length.

Discrimination

Discrimination law does not pause during probation. If dismissed because of race, ethnicity, disability, pregnancy, sex, sexual orientation, religion, age, or gender reassignment, the dismissal breaches the Equality Act 2010 from day one.

Discrimination takes two forms: direct (overt treatment based on a protected characteristic) and indirect (neutral policy with disproportionate impact, without justification). Victimisation, dismissal because you made a protected complaint about discrimination, harassment, or equal pay, is a separate unlawful act. The employer will normally need to show that the dismissal was unrelated to that complaint

Whistleblowing

Protected disclosure (whistleblowing) under the Public Interest Disclosure Act 1998 covers illegal conduct, breach of legal obligation, miscarriage of justice, and health and safety dangers. Disclosures need not be formal; conversations, emails, or team comments count if they concern a qualifying matter. Retaliation extends beyond dismissal: demotion, suspension, exclusion, or adverse treatment all qualify as unlawful detriment.

Statutory rights

Statutory rights include family leave, jury service, working time enforcement, and health and safety participation. Dismissal for asserting these rights is automatically unfair regardless of probation status.

Understanding your legal claim requires clarity on three critical factors: time limits, evidence standards, and the burden of proof:

1. A three-month time limit applies to discrimination, whistleblowing, and statutory right claims from dismissal date; limited exceptions exist only in exceptional circumstances.
2. Document the disclosure (date, recipient, content), the complaint raised, and any subsequent dismissal communication to establish causation.
3. Once you establish a prima facie case (initial evidence of differential treatment or protected disclosure), the burden shifts to the employer to prove non-discriminatory or non-retaliatory reason.

Notice requirements during probation: Statutory minimums and contractual terms

Notice requirements during probation period are governed by statute: one week minimum unless your contract specifies longer. Employers cannot waive or reduce notice below one week unilaterally. Contracts can extend notice (e.g., two weeks), but probation-specific clauses shorter than one week are unenforceable.

Payment in lieu of notice (PILON) is lawful if contractually permitted or mutually agreed. Garden leave (continued pay without work) is also lawful. The employer should provide notice in writing with a clear effective date.

• Failure to provide notice may entitle you to recover one week’s salary as damages unless you waive it or PILON applies.
• PILON is lawful only if contractually agreed; employers cannot impose it unilaterally without contractual authority.
• Verbal notice may be procedurally challengeable; written notice with a clear effective date is essential.
• Check your employment contract for probation-specific notice clauses; if none exist, one week applies automatically.

How to fight dismissal on probation: Legal grounds and evidence strategy

Fighting dismissal during probation requires identifying a protected legal ground: discrimination, whistleblowing, statutory right assertion, or automatically unfair reason. Generic capability or conduct dismissals, however procedurally flawed, fall outside unfair dismissal protection before two years of service. Protected elements change the entire legal landscape.

The burden shifts to the employer once you establish a prima facie case (initial evidence of discrimination or protected disclosure). At that point, they must prove the dismissal was unrelated to the protected element.

• Gather dismissal letter, employment contract, performance feedback, work emails, and records of any protected complaint you made.
• Collect evidence of how similarly-situated employees of different protected characteristics were treated (for discrimination claims).
• For whistleblowing claims, document what you disclosed, when, to whom, and the context in which you made the disclosure.
• Act within three months; contact ACAS or a solicitor promptly to preserve your rights and start evidence preservation.

Upcoming changes to probationary dismissal law (2027)

From 1 January 2027, significant reforms to employment law will change the legal landscape for probationary dismissal claims:

• The qualifying period for ordinary unfair dismissal claims reduces from two years to six months’ continuous service, meaning probationary employees dismissed after six months will be able to claim unfair dismissal on grounds of procedural or substantive unfairness.
• Time limits for bringing tribunal claims are expected to extend from three months to six months, giving claimants greater flexibility to gather evidence and pursue claims.
• The statutory cap on unfair dismissal compensation will be abolished, meaning awards could become uncapped and potentially significantly higher than under current law.
• Until 1 January 2027, the two-year qualifying period and three-month time limits described in this article remain in force; from that date, the six-month threshold and extended time limits will apply to new claims.

If you are dismissed in 2026, the current two-year qualifying period and three-month time limit apply; if dismissed from 1 January 2027 onwards, seek updated legal advice reflecting the new six-month regime and extended time limits.

FAQs

Can you claim unfair dismissal during probation? Only if the reason is automatically unfair (whistleblowing, discrimination, statutory right assertion) or if you have reached two years of continuous service. Most probationary dismissals for underperformance or conduct do not generally qualify for unfair dismissal protection before two years.

What notice period applies during probation? Statutory minimum is one week unless your contract specifies longer. If the contract states less than one week, the statutory one-week minimum typically applies. Payment in lieu is lawful if contractually agreed.

Is discrimination protection weaker during probation? No. Discrimination law applies entirely during probation. Dismissal because of race, disability, pregnancy, sex, sexual orientation, religion, or age is unlawful regardless of probation status or employment length.

What should I do immediately after a probationary dismissal? Document the dismissal letter and stated reason. If discrimination, whistleblowing, or a protected complaint preceded dismissal, contact ACAS or an employment solicitor promptly to preserve your rights.

Is probationary dismissal without notice ever lawful? Only if your contract explicitly permits immediate dismissal and you are paid in lieu of notice. The statutory minimum notice period generally applies unless overridden by written contract, and that override must be clear.

Probationary dismissal is not automatically unfair, but probation does not remove discrimination, whistleblowing, or statutory rights protections. If dismissed for reasons unrelated to protected grounds, the unfair dismissal regime generally does not apply before two years of service. Time limits are typically strict. Act promptly upon dismissal.

KEY TAKEAWAYS:

• Probation does not suspend discrimination, whistleblowing, or statutory rights protection; dismissal on these grounds is unlawful regardless of probation status or employment length, and these claims generally require no two-year qualifying period.
• Unfair dismissal during probation generally requires either two years of continuous service or an automatically unfair reason such as protected disclosure, trade union activity, or statutory right assertion; most capability or conduct dismissals during probation generally fall outside unfair dismissal scope.
• Time limits are typically strict and non-negotiable; claims are generally subject to a three-month deadline from dismissal, and contacting ACAS for early conciliation promptly preserves your right to claim and unlocks a free settlement process before tribunal costs arise.
