At Franklins Solicitors, we support employers through every step of the dismissal process, from risk assessment and internal procedures to tribunal defence, helping reduce the likelihood of costly claims.
Who Can Bring an Unfair Dismissal Claim?
At the time of writing, in most cases, an employee must have completed at least two years of continuous service to be eligible to bring a claim for unfair dismissal. However, there are exceptions, including dismissals related to whistleblowing, discrimination, health and safety, or exercising statutory rights, in which case no qualifying service period is required.
However, the new Employment Rights Bill introduces key changes, including making unfair dismissal a “day one” right and implementing a statutory probationary period (IPE) for simplified dismissals, with expected implementation by Autumn 2026.
What Makes a Dismissal Fair?
Employers must show that a dismissal was for a fair reason and that a reasonable and lawful procedure was followed. The five potentially fair reasons for dismissal are:
- Conduct
If an employee’s behaviour breaches company policy or is deemed unacceptable, dismissal may be justified on conduct grounds. This could include:
- Gross misconduct, leading to summary dismissal without notice
- Misconduct following a series of disciplinary warnings
Even in serious cases, a fair disciplinary procedure must still be followed to reduce the risk of a successful claim.
- Redundancy
Redundancy occurs when a role is no longer required, often due to business restructure, closure, or reduced staffing needs. To fairly dismiss on the basis of redundancy, employers must:
- Follow a fair selection and consultation process
- Use objective criteria to determine who is at risk
- Explore suitable alternative employment opportunities
- Comply with collective consultation requirements if 20 or more employees are affected within a 90-day period
Failing to follow these steps can render the redundancy unfair.
3. Capability or Performance
An employee may be fairly dismissed due to poor performance or ill health that affects their ability to do the job. Employers must demonstrate:
- The employee was given adequate support and opportunities to improve
- Medical evidence and adjustments were considered (where relevant)
- A fair and transparent procedure was followed
4. Illegality
If continuing employment would be unlawful, for example, due to visa issues or legal restrictions, dismissal may be justified. This includes situations where:
- The employee is not legally entitled to work in the UK
- The role itself becomes legally restricted
Employers must still assess and document the circumstances thoroughly.
5. Some Other Substantial Reason (SOSR)
This is a broad category for unusual but significant reasons for dismissal, such as:
- Breakdown in working relationships
- Reputational risk
- Business reorganisations not classed as redundancy
Each case must be assessed individually to determine whether dismissal is fair.
