Dismissing a Pregnant Employee During Probation in the UK

Hiring during busy periods often means moving quickly - and probation periods help you assess fit in those early months. But what if the person you’ve hired tells you they’re pregnant, and things aren’t working out?

It’s a sensitive situation, and the stakes are high. UK law offers strong protections around pregnancy and maternity, and a misstep can result in costly claims. The good news is that with the right process and documentation, you can manage performance or conduct concerns fairly and lawfully - without discriminating.

In this guide, we explain what UK law says about dismissing a pregnant employee during probation, the risks to watch, and a step-by-step process to follow if dismissal is genuinely necessary for reasons unrelated to pregnancy.

Can You Dismiss A Pregnant Employee During Probation In The UK?

Short answer: yes, you can dismiss a pregnant employee during probation - but only if the reason is entirely unrelated to pregnancy or maternity, and you follow a fair, evidence-based process.

Two key principles shape the legal landscape here:

• Pregnancy and maternity are protected characteristics under the Equality Act 2010. Any unfavourable treatment because of pregnancy, a pregnancy-related illness, or maternity leave is unlawful discrimination.
• Dismissal connected to pregnancy or maternity is “automatically unfair” under UK employment law. There’s no minimum qualifying service needed for an employee to bring this claim.

Probation doesn’t reduce these protections. Even in the first few weeks of employment, decisions that are influenced by pregnancy or pregnancy-related absence can lead to discrimination and automatic unfair dismissal claims.

So, the crucial question isn’t “Is the employee on probation?” - it’s “What is the real reason for dismissal, and can we show our process was fair?” Strengthen your position by ensuring your probation process is clear, consistent and well-documented. If you’re setting up or refreshing your early-stage hiring framework, it’s worth baking this into your Employment Contract and related HR documents from day one.

Risks And Legal Grounds You Must Consider

If performance or conduct issues arise during probation, your next steps depend on the underlying facts. Here’s how the risk profile typically looks.

Automatically Unfair Dismissal

A dismissal is automatically unfair if the reason (or principal reason) is pregnancy, a pregnancy-related illness, or maternity leave. There’s no minimum service needed to bring this claim.

Practical examples of high-risk decisions include:

• Counting pregnancy-related sickness absences against absence thresholds.
• Moving straight to dismissal after disclosing pregnancy without any performance management steps.
• Refusing reasonable time off for antenatal appointments and then citing “commitment” issues.

Discrimination (Equality Act 2010)

Any unfavourable treatment because of pregnancy or maternity is unlawful. This can include changing duties, reducing hours, or ending employment if pregnancy plays any part in the decision. Tribunals will look at timing, comments made, comparators, and whether your process differed from how you treat non-pregnant staff.

Health And Safety Duties

Once notified that an employee is pregnant, you must assess workplace risks and make reasonable adjustments (for example, adjusting heavy lifting, exposure to hazards, or scheduling). If the job can’t be done safely with adjustments, consider suitable alternative work or suspension on full pay. Cutting corners here and then dismissing can look like the decision was pregnancy-related.

Genuine Business Or Conduct Reasons

Where there are robust, non-pregnancy reasons - for example, persistent lateness unrelated to antenatal care, substantiated misconduct, or clearly documented underperformance - dismissal can be lawful if you follow a fair process. Evidence is key. If misconduct is involved, follow an investigation and hearing process that aligns with your policies and the ACAS Code. Our step-by-step overview of Workplace Investigations is a helpful benchmark.

Pay, Benefits And Other Rights On Dismissal

If you proceed to dismissal for a lawful reason, ensure you meet all exit obligations, such as:

• Contractual or statutory notice (or pay in lieu).
• Accrued holiday pay.
• Any outstanding wages or commissions.

In some cases, a pregnant employee may still qualify for Statutory Maternity Pay (SMP) or Maternity Allowance depending on earnings and timing, even if employment ends - so handle payroll queries carefully and provide timely information.

A Fair, Lawful Process Step By Step

The safest approach is consistent, transparent management that you would apply to any employee in the same situation. Here’s a practical framework.

1) Separate The Reason From Pregnancy

Start by asking: what is the specific issue? Is it performance against measurable targets, a conduct breach, or a role fit problem? Write this down in neutral, factual terms, backed by examples and dates. If pregnancy, antenatal appointments, or pregnancy-related absence play any part, stop and seek advice.

2) Do A Health And Safety Check

Once you’re aware the employee is pregnant, carry out a risk assessment and record adjustments. If any performance concerns might be linked to unsafe conditions or a lack of reasonable adjustments, fix those first and allow time for improvement.

3) Provide Clear Feedback And Support

Explain concerns early, ideally in a probation review meeting. Set out expectations in writing, agree measurable objectives, provide support or training, and set a reasonable review period. If antenatal appointments affect scheduling, accommodate them and adjust targets where appropriate.

4) Consider A Probation Extension

If progress is mixed but there’s a chance of improvement, a short extension can be reasonable. Ensure your right to extend and the notice mechanics are set out in the Employment Contract, and confirm the extension in writing with new objectives and dates.

5) Investigate Concerns Properly

For conduct or serious performance allegations, gather evidence before taking action. Speak to witnesses, review documents, and provide the employee with the information you’re relying on. Follow an investigation and hearing process aligned with your disciplinary policy and the ACAS Code. A documented, even-handed approach is critical (see the practical flow for Workplace Investigations).

6) Invite To A Meeting And Allow Representation

Write to the employee setting out the concerns, the possible outcomes (including dismissal), and their right to be accompanied at a disciplinary or capability hearing. Share evidence in advance and give reasonable notice.

7) Make A Balanced Decision

After the meeting, weigh the evidence and the employee’s response. Ask yourself: would we make the same decision if the employee wasn’t pregnant? Does our reasoning stack up on paper? Are we applying our policies consistently? If the answer is yes, document your rationale.

8) Communicate The Outcome And Appeal Rights

Confirm the decision in writing. If dismissing, confirm the lawful reason, notice or pay in lieu, termination date, holiday pay and any property to be returned. Offer an appeal. A clear paper trail helps demonstrate fairness and can reduce dispute risk.

9) Process The Exit Cleanly

Handle final pay correctly and promptly, return personal data and property as required, and issue any statutory forms. If you use a checklist when Ending An Employment Contract Fairly, you’ll reduce loose ends that often escalate into grievances.

Documents And Policies To Have In Place

Your best defence is a strong HR framework that you actually follow. At minimum, ensure the following are up-to-date and consistently used.

Employment Contract

A well-drafted Employment Contract should include a clear probation clause (length, extension, reviews), performance expectations, notice provisions, and links to policies. It should also explain any right to pay in lieu of notice.

Staff Handbook And Core Policies

Your Staff Handbook should include disciplinary, capability and grievance procedures, absence management, and equality/anti-discrimination standards. Having a comprehensive Staff Handbook Package makes it easier to demonstrate consistent processes and meet the ACAS Code.

Standalone Policies Where Needed

Some businesses prefer standalone policies for clarity and training. For example, a disciplinary or equality policy can be issued as a separate document for easy reference. If you’re formalising or updating your framework, a tailored Workplace Policy helps align day-to-day practices with legal standards.

Investigation And Hearing Templates

Use consistent letters for investigation invitations, hearing notices, outcome letters and appeal confirmations. Templates ensure you cover rights to be accompanied, the issues at stake, and reasonable timeframes.

Manager Training Notes

Make sure line managers know the basics: pregnancy protections, adjustments, antenatal time off, and when to escalate to HR. Small, practical guides prevent accidental missteps like counting pregnancy-related sickness as “absence triggers”.

Common Mistakes Employers Make (And How To Avoid Them)

Most legal issues in this area arise from process slips rather than bad intentions. Here are common pitfalls and how to stay on the right side of the line.

1) Letting Pregnancy Influence Timing Or Tone

Even subtle comments like “we need someone more reliable now you’re pregnant” can be strong evidence of discrimination. Stick to neutral language focused on specific performance or conduct facts.

2) Counting Pregnancy-Related Absence As A Mark Against Performance

Sickness or absence due to pregnancy must not be used for disciplinary action or dismissal. Adjust targets and schedules where antenatal care or pregnancy-related illness affects availability.

3) Skipping Investigation Or Meetings During Probation

“On probation” isn’t a free pass to bypass fair procedure. Tribunals expect you to raise concerns, provide a chance to respond, and make a reasoned decision. Keeping to a clear process also reduces the risk of claims - a theme that often features in why Employers Lose Employment Tribunals.

4) No Paper Trail

If it isn’t written down, it’s hard to prove later. Keep concise notes of meetings, objectives, and evidence considered. Confirm key points by email. Use consistent templates where possible.

5) Overlooking Health And Safety Adjustments

Failure to assess risks and make reasonable adjustments can undermine a capability or conduct case and suggest the issue was pregnancy-related. Do the assessment early and record your actions.

6) Rushing To Dismiss Instead Of Extending Probation

Where there’s partial progress, a short, reasonable extension with clear objectives can show fairness and give you better evidence of the outcome either way. Just ensure your contract allows for extensions and you confirm the terms in writing.

7) Inconsistent Treatment Across The Team

If similar issues were handled more leniently for non-pregnant colleagues, expect close scrutiny. Align your decision with past practice and your written policies, or document why this case is materially different.

Key Takeaways

• You can dismiss a pregnant employee during probation in the UK, but only for reasons that are not connected to pregnancy or maternity - and only after a fair, well-documented process.
• Pregnancy and maternity are protected: decisions influenced by pregnancy, pregnancy-related illness, or maternity leave can amount to discrimination and automatic unfair dismissal, with no minimum service needed to claim.
• Follow a clear process: identify the non-pregnancy reason, carry out a health and safety risk assessment, give feedback and support, consider a probation extension, investigate properly, hold a hearing, and confirm outcomes in writing.
• Get your foundations right: use a robust Employment Contract, maintain a practical Staff Handbook, and align day-to-day practice with your Workplace Policy documents.
• Avoid common pitfalls: don’t count pregnancy-related absence, don’t shortcut investigations, and ensure your language and timing don’t suggest pregnancy influenced the decision.
• If you do proceed to dismissal, meet all exit obligations (notice or PILON, accrued holiday pay, final wages) and use a checklist when Ending An Employment Contract Fairly.
