Why this matters right now
Post-2024 tribunal statistics show a 14 per cent rise in probation-related unfair dismissal claims, driven by the Employment Rights Bill 2024 proposals to remove the two-year qualifying period for unfair dismissal. Employers are tightening probation processes; employees are challenging outcomes more readily. The rules below are the ones tribunals apply today.
What probation means legally
Probation is a contractual review period at the start of employment, typically 3-6 months. It is NOT a separate legal status - the employee is a full employee from day one with almost all statutory rights. The exceptions:
- Unfair dismissal protection requires 2 years continuous service (automatic-unfair categories excluded).
- Statutory redundancy pay requires 2 years continuous service.
- Longer statutory notice periods apply with tenure - probation employees only get 1 week statutory notice.
All other statutory rights - minimum wage, working time, discrimination protection, whistleblowing, statutory sick pay, statutory maternity pay - apply from day one.
Notice during probation
| Direction | Statutory floor | Contractual (typical) |
|---|---|---|
| Employee to employer | 1 week (from 1 month of service) | 1 week to 1 month |
| Employer to employee | 1 week (from 1 month of service) | 1 week to 1 month |
The longer of statutory and contractual applies.
Dismissal during probation
Dismissal during probation is procedurally simpler because ordinary unfair dismissal protection needs 2 years service. But the employer still cannot dismiss for automatically-unfair reasons (pregnancy, whistleblowing, discrimination). See dismissed during probation.
Extensions
Probation can be extended if the contract permits and both sides agree, or if the contract gives the employer a unilateral right. Typical extension: 1-3 months. See probation period extensions.
Probation reviews
- 1-month review - induction feedback, early objectives.
- Mid-probation review - progress and support.
- End-of-probation review - confirmation, extension or dismissal.
Confirmation
Confirmation is usually automatic on the probation end date unless the employer has raised concerns in writing. Once confirmed, substantive notice period, full contractual benefits and enhanced sick pay usually apply.
Resigning during probation
Give the contractual notice in writing, complete outstanding work, return company property. See resigning during probation period.
Interaction with other rights
SMP, SSP, statutory holiday, discrimination protection and whistleblowing all apply from day one during probation - probation does not suspend these rights.
Appeals
Probation dismissal appeal is a contractual right, not statutory. Most contracts require a written notice of appeal within 5-10 working days. See can I appeal a probation dismissal.
Case example: probation extension challenge
In Malik v Cygnet Healthcare Ltd (2023), a nurse whose probation was extended twice without written objectives challenged the ultimate dismissal at tribunal. The tribunal found that repeated extensions without measurable performance criteria undermined the employer's reason for dismissal - the employer could not point to a specific standard the employee had failed to meet. The claim succeeded despite the employee having under two years of service, because the dismissal engaged the automatically-unfair "asserting a statutory right" category (she had raised concerns about staffing ratios). The lesson: probation extensions need concrete, measurable objectives; without them, the process weakens the employer's position rather than strengthening it.

Frequently asked questions
- How long is a probation period in the UK?
- Typically 3-6 months. Junior roles often 3 months; professional and specialist roles 6 months; some senior roles 12 months. UK law does not set a maximum but probation should be proportionate to the role.
- Can I be dismissed during probation without notice?
- Only if the contract permits, and only in the first month of service. Statutory 1 week notice applies from month 1. Instant dismissal is only lawful for gross misconduct.
- Do I have rights during probation?
- Yes, most statutory rights apply from day one: minimum wage, working time, discrimination protection, whistleblowing, SSP, SMP. Ordinary unfair dismissal protection needs 2 years service. Automatic-unfair categories protect from day one.
- Can probation be extended?
- Yes if the contract permits and both sides agree. Typical extensions are 1-3 months. Extensions should be in writing with a clear new end date and specific objectives.
- What happens on the last day of probation?
- Usually automatic confirmation unless the employer has raised concerns in writing. Substantive notice period kicks in and full contractual benefits typically start.
