Dismissed for posting racism allegations on Yammer: tribunal finds fair process

What this case shows in practice

A long-serving general assistant at Sainsbury's was summarily dismissed after posting on the internal Yammer network that some managers had 'racist mindsets and tendencies'. He had previously raised a fair treatment complaint and brought a tribunal claim, but his dismissal was triggered by the Yammer posts and a subsequent conversation with a manager about a colleague's racist comments.

The tribunal found that the conversation did not amount to a protected disclosure because the claimant did not provide specific details about the racist remarks. The dismissing officer, who was independent, concluded that the claimant had made spurious allegations on a public forum, breached his suspension by posting again, and broke confidentiality. The tribunal held that this was a reasonable decision within the range of responses open to a reasonable employer.

What the losing side could have done differently

The claimant argued that his dismissal was automatically unfair because he had made a protected disclosure about a manager's racist comments. However, the tribunal noted that he had not given specific details during the conversation with his manager. If he had provided clear information about the alleged racist remarks, the outcome might have been different. Additionally, posting on Yammer after being suspended was a clear breach of the suspension terms, which undermined his case.

Why the result matters for similar claims

This case highlights that employees who raise discrimination concerns must do so in a specific and measured way. General social media posts accusing managers of racism, without concrete details, are likely to be seen as misconduct rather than protected disclosures. Employers can safely dismiss for such conduct if they follow a fair process, including an independent investigation and a reasonable decision-making process.
