The outcome

The tribunal dismissed the claim for constructive unfair dismissal.

The key reasons were:

  • The alleged derogatory comments by colleagues were not acts of the employer; the employer had taken reasonable steps to address them informally.
  • The claimant did not submit a formal grievance despite being advised she could, so the employer had not failed to provide a reasonable opportunity for redress.
  • The decision to investigate the claimant's use of a car hire vehicle was a reasonable management action, not a breach of contract.

No compensation was awarded as the claim failed.

Lessons & takeaways

  • If you believe you have been bullied or harassed at work, consider submitting a formal written grievance to ensure the employer is on notice and must follow a proper procedure.
  • Informal complaints may not be enough to establish a breach of the implied term of trust and confidence – the employer must have a reasonable opportunity to address the issue formally.
  • Resigning before exhausting the employer's internal grievance procedure can weaken a constructive dismissal claim, as the tribunal may find you affirmed the contract.
  • Conduct by colleagues that is not endorsed by the employer may not be attributed to the employer for the purposes of constructive dismissal.

What this case shows in practice

This case highlights the importance of using formal grievance procedures when an employee feels they are being bullied or harassed. The claimant, an Operational Support Grade at HMP Garth, alleged that colleagues made derogatory comments and called her names over a period of two years. She raised these concerns informally with managers, but never submitted a formal written grievance. When she resigned after being told an investigation into her use of a car hire vehicle would proceed, she claimed that the employer's failure to address her complaints amounted to a fundamental breach of contract.

The tribunal found that the employer had acted reasonably. Managers had investigated her informal complaints, offered mediation, and repeatedly advised her that she could pursue a formal grievance if she wished. The alleged conduct by colleagues was not attributed to the employer because there was no evidence that the employer condoned or was responsible for it. The tribunal also noted that the decision to investigate the car hire issue was a legitimate management action, not a breach of trust and confidence.

What the employer did right

The employer's response to the claimant's informal complaints was key to defeating the claim. Managers met with the claimant, listened to her concerns, and offered her the option of a formal grievance procedure. They did not ignore her complaints or dismiss them out of hand. By providing a reasonable opportunity for redress, the employer avoided a finding that it had fundamentally breached the employment contract.

Why this matters for similar claims

For employees considering a constructive dismissal claim, this case is a reminder that informal complaints may not be enough. To establish a breach of the implied term of trust and confidence, the employer must have acted (or failed to act) in a way that is likely to destroy or seriously damage the relationship. If the employer offers a proper avenue for redress, such as a formal grievance procedure, and the employee does not use it, a tribunal is likely to find that the employer has not breached the contract. Resigning without giving the employer a fair chance to put things right can be fatal to a claim.
