The legal issue
The tribunal had to decide whether the dismissal for misconduct was fair under the Employment Rights Act 1996, focusing on whether the employer genuinely believed the employee had committed misconduct, had reasonable grounds for that belief, and conducted a reasonable investigation.
The outcome
The tribunal dismissed the claim for unfair dismissal, ruling that Cordant Cleaning Limited acted fairly.
Key reasons:
- The employer had a genuine belief that the shunter breached a safety alert by using his mobile phone outside a designated area.
- The employer conducted a reasonable investigation, including witness statements and a proper disciplinary process.
- The shunter's refusal to attend the disciplinary hearing did not make the process unfair.
- The allegation of working for a competitor was not proven, but the other reasons were sufficient to justify dismissal.
No compensation was awarded as the claim failed.
Lessons & takeaways
- Safety-critical rules are taken seriously by tribunals; breaching them can justify dismissal even for long-serving employees.
- Refusing to attend disciplinary meetings can harm your case, as the employer may proceed in your absence.
- Employers should ensure they have a genuine belief in misconduct based on reasonable grounds and a fair investigation.
- If you are representing yourself, ensure you understand the legal issues and present evidence clearly.
This case shows how employment tribunals assess fairness when an employee is dismissed for breaching a safety rule. The shunter, who had worked for the company for six years, was seen using his mobile phone outside a designated area, in direct contravention of a safety alert. The employer suspended him and invited him to a disciplinary hearing, which he did not attend. The tribunal found that the employer had a genuine belief in the misconduct and had carried out a reasonable investigation, including obtaining witness statements and considering the employee's explanations.
What the employer did right
Cordant Cleaning Limited followed a structured process: they suspended the employee, investigated the incident, and invited him to a disciplinary hearing. Even though the employee refused to attend, they proceeded and gave him the opportunity to appeal. The tribunal noted that the employer's belief in the misconduct was reasonable, and the investigation was adequate. The fact that the employee had six years' service did not outweigh the seriousness of the safety breach.
What the employee could have done differently
The shunter could have attended the disciplinary hearing to explain his side. His refusal to engage may have weakened his case. He also raised an allegation about working for a competitor, which the tribunal found unproven. Focusing on the core issue—the mobile phone breach—and cooperating with the process might have led to a different outcome.
Why this matters
This case reinforces that employers in safety-critical environments can dismiss for breaching clear rules, provided they follow a fair process. Employees should take safety alerts seriously and engage with disciplinary procedures. The tribunal's decision highlights that a reasonable investigation does not need to be perfect, but must be sufficient to form a genuine belief in misconduct.
