Key facts
- The claimant was employed as Trade Counter Sales Manager from 15 January 2018 until his dismissal on 18 December 2020.
- The claimant raised concerns about COVID-19 safety measures, including the removal of a barrier, which the tribunal found were protected disclosures.
- The respondent investigated customer complaints about the claimant's behaviour, which the tribunal found were not genuinely unprompted but were gathered by the respondent.
- The disciplinary hearing was flawed: the claimant was not given proper opportunity to respond, and the decision to dismiss was predetermined by the managing director.
- The tribunal found the dismissal was unfair because the respondent did not carry out a reasonable investigation and the decision was outside the range of reasonable responses.
- The tribunal dismissed claims of automatically unfair dismissal for whistleblowing and health and safety detriments, finding those were not the reason for dismissal.

The legal issue
The tribunal had to decide whether the dismissal was unfair, whether it was automatically unfair due to whistleblowing or health and safety concerns, and whether the employer breached the employment contract.
The outcome
The tribunal decided that the claimant was unfairly dismissed and wrongfully dismissed (breach of contract).
Key reasons:
- The employer's investigation into customer complaints was not reasonable; complaints appeared to have been gathered rather than genuinely unprompted.
- The disciplinary hearing was flawed: the claimant was not given a proper opportunity to respond, and the decision to dismiss was predetermined by the managing director.
- However, the tribunal dismissed claims of automatically unfair dismissal for whistleblowing and health and safety detriments, finding those were not the reason for dismissal.
Compensation: To be determined at a further hearing. No reductions for Polkey or contributory fault were made.
Lessons & takeaways
- Employers must carry out a genuine and reasonable investigation before dismissing for misconduct; gathering complaints from colleagues can undermine fairness.
- A disciplinary hearing must give the employee a proper opportunity to respond, and the decision must not be predetermined by senior management.
- Raising health and safety concerns does not automatically protect an employee from dismissal if the employer can show a different reason for the dismissal.
- Length of service (here nearly 3 years) is relevant to the range of reasonable responses expected from an employer.
This case shows how an employer's flawed investigation and predetermined decision-making can make a conduct dismissal unfair, even when the employee had raised protected concerns.
What went wrong
The employer, Charles Watts Engineering Limited, dismissed a Trade Counter Sales Manager after customer complaints about his behaviour. However, the tribunal found that the complaints were not genuinely unprompted but were gathered by the employer. The disciplinary hearing was also flawed: the claimant was not given a proper opportunity to respond, and the managing director had already decided on dismissal before the hearing. The tribunal concluded that the investigation was not reasonable and the decision was outside the range of reasonable responses.
What the employer could have done differently
The employer could have conducted a more thorough and impartial investigation, ensuring that complaints were independently verified. The disciplinary process should have allowed the claimant to fully respond to allegations, and the decision-maker should not have been influenced by senior management's predetermined views. Following the ACAS Code of Practice on disciplinary procedures would have helped avoid these pitfalls.
Why this matters
This case highlights that even where an employee has raised health and safety concerns, a dismissal can still be unfair if the process is flawed. However, the tribunal rejected claims of automatic unfair dismissal for whistleblowing, showing that the burden is on the employee to prove that the protected disclosure was the reason for dismissal. For employees, this underscores the importance of ensuring that any protected disclosures are clearly documented and that the employer's actions are scrutinised for procedural fairness. For employers, it is a reminder that a fair process is not just a legal requirement but also a protection against costly unfair dismissal claims.
