Baseline response (no ZPI)

Based on UK employment law (as of June 2024): **No, the employee does not have a valid claim for unfair dismissal based on length of service.** **Reason:** To claim ordinary unfair dismissal, an employee must have at least **2 years' continuous service** with their employer at the date of dismissal (Employment Rights Act 1996, s.108). The employee in your scenario has **20 months' service** (which is less than 2 years). **Exceptions:** There are some exceptions where the 2-year qualifying period does not apply (e.g., dismissals for reasons related to discrimination, whistleblowing, asserting statutory rights, etc.), but redundancy is not one of these exceptions. **Conclusion:** Unless the employee can show their dismissal falls under one of the exceptions to the qualifying period, **they do not have the right to claim ordinary unfair dismissal** after 20 months' service. **Note:** They may still be entitled to a redundancy payment (if they have at least 2 years' service) and notice pay, but not to claim unfair dismissal in this scenario.

Enhanced response (with ZPI)

No, because employees need at least two years’ continuous service to claim unfair dismissal for redundancy, and 20 months is less than two years.
