Claimant v Royal Mail Group Limited

1 December 2025Before Employment Judge AnstisReadingin person

Outcome

Partly successful

Individual claims

Unfair Dismissalsucceeded

The tribunal found the claimant's dismissal unfair due to multiple related factors: the disciplinary allegations were insufficiently clear, the respondent never properly investigated what material the claimant shared and when, and did not fully explore the allegations of dishonesty and collusion. The respondent had no reasonable grounds to conclude the claimant had acted in collusion. While the claimant did breach confidentiality rules, which constituted potential misconduct, the process was fundamentally flawed.

Failure to Make Reasonable Adjustments(disability)failed

The tribunal found that while some requirements did put the claimant at a disadvantage (e.g., being given only three days to respond to interview notes, the lack of appropriate interpreter at the 12 August meeting), in most cases the respondent did not know and could not reasonably have been expected to know that the claimant was at that disadvantage because of his disability. The claimant communicated in written English, appeared to respond adequately within deadlines, and did not request additional time or support. The respondent could not reasonably have anticipated issues with dialect differences in BSL interpreters absent any indication from the claimant.

Discrimination Arising from Disability (s.15)(disability)failed

The claimant alleged he was dismissed because he failed to understand the need for confidentiality and its consequences, arising from his disability. However, the tribunal found clear evidence that the claimant did understand the confidentiality requirements and their seriousness. He acknowledged receiving and understanding clear instructions not to discuss the case with Paula Watts. His position was that he believed he had permission to share material, not that he didn't understand the need for confidentiality. Since the 'something arising' was not established on the facts, the claim could not succeed.

Facts

The claimant, a profoundly Deaf postman with BSL as his first language and limited written English literacy, raised a bullying and harassment grievance in early 2020. During the investigation and subsequent disciplinary process concerning alleged breaches of confidentiality, he shared confidential witness statements with a colleague (Paula Watts) on two occasions, seeking help to understand documents he could not fully read. The respondent alleged this constituted gross misconduct (breach of GDPR, dishonesty, and collusion) and dismissed him in October 2020. The claimant argued he did not understand the confidentiality requirements due to his disability and that reasonable adjustments (BSL interpretation, additional time) were not provided.

Decision

The tribunal found the unfair dismissal claim succeeded because the disciplinary allegations were insufficiently clear, the investigation was inadequate (never properly establishing what was shared when, or exploring dishonesty and collusion allegations), and there were no reasonable grounds for the collusion finding. However, the disability discrimination claims failed: reasonable adjustments were not required as the respondent could not reasonably have known the claimant was disadvantaged (he appeared to cope adequately), and discrimination arising from disability failed because the claimant did understand the confidentiality requirements. A 75% Polkey reduction was applied with no contributory fault deduction to avoid double-counting.

Practical note

Employers must ensure disciplinary allegations are clear and specific, and investigations thorough, even when an employee appears to be coping adequately; however, the duty to make reasonable adjustments depends on actual or constructive knowledge of disadvantage, not just knowledge of disability.

Adjustments

Polkey reduction75%

The tribunal found that if the respondent had acted fairly, they would have discovered the claimant had twice breached confidentiality rules but found no basis for allegations of dishonesty or collusion. A fair procedure would have taken a further four weeks, after which there was a 75% chance the respondent would have fairly dismissed the claimant. The claimant had some mitigation based on the circumstances he found himself in.
