The legal issue
The tribunal had to decide whether the claimant was unfairly dismissed for conduct, whether the dismissal was automatically unfair because of protected disclosures about unauthorised use of his personal smartphone, and whether he suffered detriment for whistleblowing.
The outcome
The tribunal decided that the claimant was unfairly dismissed, but not automatically unfair for whistleblowing. The key reason was that Tesco's disciplinary process was flawed: the claimant was not given witness statements or shown CCTV footage, which made the dismissal procedurally unfair. However, the tribunal found that the reason for dismissal was his aggressive behaviour, not his protected disclosures.
Compensation will be determined at a separate remedy hearing. The tribunal did not award any damages at this stage.
Lessons & takeaways
- If you make a protected disclosure, ensure it is clearly recorded and linked to any subsequent detriment or dismissal to strengthen a whistleblowing claim.
- Employers must provide employees with relevant evidence, such as witness statements and CCTV, during disciplinary proceedings to ensure fairness.
- An angry reaction to a workplace issue may still lead to dismissal for conduct, even if the underlying issue is a protected disclosure.
What this case shows in practice
This case highlights the importance of fair process in disciplinary proceedings, even when an employee's behaviour is clearly unacceptable. The claimant, an HGV driver with two years' service, was dismissed for aggressive behaviour after he reacted angrily when managers contacted him on his personal smartphone without permission. While the tribunal accepted that his behaviour was hostile, it found that Tesco's failure to provide him with witness statements or show him CCTV footage during the disciplinary process made the dismissal procedurally unfair.
What the losing side could have done differently
Tesco could have avoided the unfair dismissal finding by ensuring the claimant had access to all relevant evidence before the disciplinary hearing. Providing witness statements and allowing him to view the CCTV footage would have given him a fair opportunity to respond to the allegations. The tribunal noted that the claimant was not even given an accurate summary of the investigation meeting, which further undermined the process.
Why the result matters for similar claims
This case demonstrates that even where an employee's conduct is the genuine reason for dismissal, procedural flaws can still lead to a finding of unfair dismissal. It also shows the difficulty of proving that a dismissal was because of whistleblowing, rather than conduct. The claimant's protected disclosures about data protection were accepted as genuine, but the tribunal found they were not the reason for his dismissal. For employees, this means that making a protected disclosure does not automatically protect them from dismissal for unrelated misconduct.
