Bus driver dismissed for refusing alcohol test after collision: dismissal fair

A clear breach of contract

This case shows that in safety-critical roles, employers are entitled to enforce strict policies on alcohol and drug testing. The bus driver had been employed for six years but was dismissed after refusing a breath alcohol test following an at-fault collision. His contract explicitly stated that refusal to undergo such a test amounted to gross misconduct. The tribunal found that the employer had a genuine belief in the misconduct and followed a reasonable process, including an investigation and disciplinary hearing.

What the employer did right

London United Busways Ltd had a clear policy, a consistent approach to testing, and a thorough disciplinary procedure. The claimant was suspended, investigated, and given a hearing before dismissal. The appeal was also considered. The tribunal noted that the testing was random and not targeted, which helped defeat the discrimination claims. The employer also had evidence that the claimant had been evasive about a previous drug test, though the dismissal was based on the alcohol test refusal.

Why this matters for similar claims

For employees in safety-sensitive jobs, this case reinforces that contractual obligations around testing are taken seriously. A refusal to comply, even if the employee believes the test is unnecessary, can justify dismissal. For employers, it highlights the importance of having clear policies, applying them consistently, and documenting the process. The dismissal of the discrimination claims also shows that random testing programmes are unlikely to be discriminatory if they are genuinely random and not based on protected characteristics.
