Case details

Key facts

  • The claimant was employed as a security officer from 13 March 2007 until dismissal on 29 March 2021.
  • On 4 January 2021, the claimant took a PCR test for Covid-19 and attended work, later testing positive on 6 January 2021.
  • The claimant had a cough but it was not a new or continuous cough; it was a side effect of his blood pressure medication.
  • The respondent dismissed the claimant for gross misconduct, alleging he attended work with Covid-19 symptoms.
  • The original disciplinary process was flawed and treated the claimant's guilt as a foregone conclusion.
  • The appeal process did not cure the defects and involved embellished evidence.

Timeline

  1. Employment start

    The claimant began employment with a previous employer, later transferring to the respondent.

  2. TUPE transfer

    The claimant's employment transferred to Profile Security Services Ltd under TUPE.

  3. PCR test and work shift

    The claimant took a PCR test for Covid-19 and attended his shift at the Thames Barrier.

  4. Positive test result

    The claimant received notification of a positive Covid-19 test and informed his line manager.

  5. Deallocated from shifts

    The respondent informed the claimant he was deallocated from shifts.

  6. Investigation meeting

    An investigation meeting was held with Steve Marsters.

  7. Disciplinary meeting

    A disciplinary meeting was chaired by Eugene Jonas.

  8. Dismissal

    The claimant was dismissed without notice for gross misconduct.

  9. Appeal investigation start

    Appeal investigation meetings began, conducted by Mr Ely.

  10. Tribunal hearing

    The substantive hearing took place over two days.

The outcome

The tribunal ruled that the claimant was unfairly dismissed. The disciplinary process was flawed because the investigator treated the claimant's guilt as a foregone conclusion and the appeal did not remedy this. A 60% Polkey reduction was applied, meaning the claimant would have been dismissed anyway in 60% of scenarios. No contributory fault was found.

  • Unfair dismissal: successful
  • Wrongful dismissal: successful (breach of contract for no notice)
  • Polkey reduction: 60%
  • Contributory fault: 0%

Lessons & takeaways

  • Employers must not treat a disciplinary outcome as predetermined; a fair investigation requires an open mind.
  • An appeal process that relies on embellished evidence or fails to correct original defects will not save a flawed dismissal.
  • Long-serving employees with clean records are entitled to a thorough and impartial process before dismissal for misconduct.

A flawed process from the start

This case highlights how a rushed and biased disciplinary process can lead to an unfair dismissal, even when the underlying allegation is serious. The security officer, who had 14 years of unblemished service, was dismissed for attending work while waiting for a Covid-19 test result after developing a cough. However, the tribunal found that the cough was a side effect of his blood pressure medication, not a Covid-19 symptom. The employer's investigation assumed guilt from the outset, and the dismissing officer did not consider the claimant's explanation properly.

What the employer could have done differently

The employer could have avoided this outcome by conducting a more balanced investigation. Instead of treating the claimant's attendance as an automatic breach of Covid-19 rules, they should have explored whether he genuinely believed he was symptom-free. The appeal process also failed: the appeal officer embellished evidence and did not correct the original defects. A fair process would have given the claimant a proper opportunity to respond and would have considered his long service and clean record.

Why this matters for similar claims

This decision reinforces that even in the context of a pandemic, employers must follow fair procedures. A dismissal based on a flawed investigation and a predetermined outcome will be found unfair, regardless of the seriousness of the alleged misconduct. The 60% Polkey reduction reflects that the claimant might still have been dismissed if a fair process had been followed, but the employer's failures meant the dismissal was not within the range of reasonable responses. For employees, this case shows that a long service record and a lack of prior issues can strengthen a claim of unfair dismissal when the process is defective.
