Machine Room Manager dismissed after blocking subordinate: conduct dismissal upheld

What this case shows in practice

This case illustrates how tribunals assess the fairness of a conduct dismissal when the employee admits the key facts. The Machine Room Manager, who had eight years' service, accepted that he raised his voice and physically blocked a subordinate from leaving a cleaning room during a heated argument. The employer, UHV Design Limited, dismissed him for gross misconduct after a disciplinary hearing.

The tribunal focused on whether the employer followed a fair process and whether dismissal was a reasonable response. Despite the manager's long service and the fact that the subordinate had also used foul language, the tribunal found that the employer acted reasonably. The manager's admission of physically blocking the exit was critical — it meant the employer did not need to resolve disputed facts.

What the losing side could have done differently

The manager's decision not to appeal the dismissal was a significant factor. The tribunal noted that an appeal could have addressed his concerns about the process, such as the timing of witness interviews. By not appealing, he missed an opportunity to show that the employer's decision was flawed. Additionally, while the manager expressed contrition, he did not fully acknowledge the seriousness of physically blocking a colleague, which the employer and tribunal viewed as a serious breach of trust.

Why the result matters for similar claims

This case reinforces that employers can dismiss for a first offence of gross misconduct if the conduct is serious enough, even for long-serving employees. Physical blocking, even without violence, can be treated as gross misconduct. It also highlights that a fair investigation does not need to be perfect — it must be reasonable in the circumstances. Employees who admit misconduct should consider appealing if they believe the process was unfair, as failing to do so may harm their claim.
