Dismissal during probationary period can be straightforward and low risk when you follow a fair, documented process. I’m John Bloor from EBS Law, and in this guide I explain what you can (and should) do when a new hire isn’t working out, how to manage notice and pay, and how to avoid the traps that lead to costly claims.
Managing risk while keeping the dismissal during probationary period process proportionate
A probation is a contractual trial period, not a separate legal status. Consequently, the usual rules of employment law still apply. Although ordinary unfair dismissal protection typically requires two years’ service, some claims arise from day one — for example, discrimination, whistleblowing, health and safety, trade union activity, or asserting statutory rights. Therefore, you must be confident the reason for ending employment is legitimate and untainted by a protected reason.
At the same time, you do not need to run a full disciplinary process to end a short-service contract for performance or fit. However, you should still act reasonably: raise concerns early, give short, focused feedback, and record what happened. ACAS guidance stresses that employers should use a fair and reasonable procedure and deal correctly with notice, especially where gross misconduct is alleged. You can read the ACAS overview on dismissals and notice here: ACAS: dismissals with and without notice.
When is dismissal during probationary period appropriate?
In many cases the new starter is simply not meeting the required standards despite support. In others, conduct issues or cultural fit make continued employment impractical. Provided the reason is not discriminatory or automatically unfair, and you give the correct notice (unless it is genuinely gross misconduct), dismissal during probationary period is usually lawful. You should still balance legal risk, costs, role criticality, and the likelihood of improvement.
A short, fair process that protects your business
You can keep the process light but robust. Follow these steps and you’ll place your company in the strongest position if the decision is later challenged:
- Identify specific concerns. Refer to measurable performance gaps, attendance issues, or clear conduct examples. Avoid vague labels such as “not a team player”.
- Give focused feedback. Meet with the employee and explain concerns. Confirm any training offered, shadowing, or targets. Keep brief notes.
- Allow a short opportunity to improve. Where possible, set clear expectations with a tight timeframe (for example, one to two weeks) and state that employment may end if improvement is not achieved.
- Hold a final meeting. Invite the employee, outline the evidence, and take their response. You may allow a companion as good practice.
- Decide and confirm in writing. If you proceed to dismissal during probationary period, give written reasons in neutral terms, confirm notice arrangements, last working day, pay in lieu if applicable, and the right of appeal.

Notice, pay and holiday when ending probation
Check the contract first. Most contracts either provide a reduced notice during probation (often one week) or the standard contractual notice. If the employee has at least one month’s service, statutory minimum notice is one week unless you are dismissing for gross misconduct. For non-misconduct cases you may either ask them to work their notice or pay in lieu if the contract allows. Confirm any accrued but untaken holiday pay and reimburse reasonable expenses.
Only dismiss without notice where gross misconduct genuinely applies and you have a fair basis for that decision. Even then, follow a reasonable process to investigate and hear their response.
Capability, performance and possible disabilities
Sometimes performance concerns point to an underlying health condition or disability. If that may be the case, pause and consider reasonable adjustments, medical input, or an extension to probation. Dismissing during probation in the face of a potential disability issue can lead to discrimination claims from day one. A short, well-documented adjustment period can significantly reduce risk and is often the fairest outcome for both sides.
Pregnancy, whistleblowing and other automatically unfair reasons
Be particularly careful if the employee has recently raised health and safety concerns, requested family-related leave, joined a trade union, or disclosed wrongdoing. Terminating employment in those situations may constitute an automatically unfair dismissal regardless of length of service. Where in doubt, seek advice before you act.
Extending probation or offering an alternative exit
If the employee shows promise but has not quite met the bar, an extension (where the contract permits it) can be a sensible middle ground. Set precise objectives and review dates. Alternatively, where trust and confidence have broken down, a mutually agreed exit with an appropriate payment and a basic reference may be quicker and less contentious. A protected conversation or early settlement can be managed lawfully with the right wording.
Letters and records you should keep
Good paperwork needn’t be long. Keep the contract of employment, probation review notes, any targets or training offered, invitation letters or emails for meetings, a brief outcome letter, and a payroll record of notice and holiday pay. These documents provide the audit trail that shows you acted reasonably if the decision is later questioned.
A concise checklist before you dismiss
- Is the reason for dismissal during probationary period non-discriminatory and not automatically unfair?
- Have you given clear feedback and a short chance to improve where appropriate?
- Have you checked whether disability, pregnancy, or other protected issues might be relevant?
- Are you using the correct contractual or statutory notice, or paying in lieu?
- Have you confirmed the decision in writing and offered a brief appeal?
How to communicate the dismissal during probationary period decision professionally
Plan the meeting. Be courteous, concise, and factual. Explain that, despite support, the required standards have not been reached or that conduct fell below expectations. Confirm that the decision is dismissal during probationary period, set out notice or payment in lieu, state the last day of employment, and signpost the right of appeal. After the meeting, issue the written confirmation promptly and inform payroll and IT so off-boarding happens smoothly.
Frequently asked employer questions
Can we end employment without meetings? I recommend at least one short review and a final meeting. It adds minimal time but significantly reduces risk and demonstrates reasonableness.
Must we give reasons in writing? While short-service dismissals do not require detailed reasons, a brief explanation shows transparency and helps avoid speculation about protected reasons.
Can we rely on “poor cultural fit”? Use objective examples — communication, accuracy, attendance — rather than labels. Objective evidence travels well if challenged.
What about references? Provide a short, factual reference confirming dates and job title unless your policy says otherwise. Avoid subjective commentary.
Handled correctly, dismissal during probationary period is a lawful management tool. However, a few minutes of planning — checking the contract, taking a short statement of the issues, and confirming notice and pay — can save days of management time later. If you are uncertain, call me for a quick view before you act.
