  12. Resignation

    Claimant resigned with immediate effect, citing cumulative bullying and the failure to agree the meeting note as the last straw.

The outcome

The tribunal dismissed all claims for unfair dismissal, wrongful dismissal, holiday pay, and arrears of pay.

The key reasons were:

  • The manager's behaviour (raising her voice on two occasions) did not constitute bullying.
  • The employer conducted a reasonable grievance investigation and appeal, which did not uphold the bullying allegations.
  • The final straw – a disagreement over the grievance appeal meeting notes – was not a repudiatory breach of the implied term of trust and confidence.

No compensation was awarded as the claims were dismissed.

Lessons & takeaways

  • A single raised voice or moment of frustration is unlikely to amount to bullying or a breach of trust and confidence, especially if it is not part of a pattern.
  • Employers who carry out a reasonable grievance investigation and appeal process can defend against constructive dismissal claims based on mishandled complaints.
  • The 'last straw' must be a genuine breach of contract – a disagreement over meeting notes is unlikely to be sufficient to justify resignation.
  • Employees considering a constructive dismissal claim should ensure they have clear evidence of a fundamental breach before resigning.

When a grievance process can protect an employer

This case shows that an employer's reasonable handling of a grievance can be a strong defence against a constructive dismissal claim. The architectural assistant alleged bullying by his manager over several incidents spanning two years, including raised voices and critical feedback. However, the tribunal found that the manager's conduct did not cross the line into bullying – it was performance management, albeit delivered in a direct manner.

The employer investigated the grievance thoroughly, appointing a manager to hear the complaint and a separate appeal officer. Neither upheld the bullying allegations, though recommendations were made. The tribunal accepted that this process was reasonable, meaning the employer had not breached the implied term of trust and confidence.

The importance of the 'last straw'

The claimant's final straw was a dispute over the notes of his grievance appeal meeting. He argued that the employer's failure to agree the notes amounted to a breach. The tribunal disagreed, noting that this was a minor procedural disagreement, not a fundamental breach of contract. This highlights that the 'last straw' must be more than a trivial issue – it must be capable of contributing to a breakdown in trust and confidence.

What this means for similar claims

For employees, this case is a reminder that constructive dismissal claims are difficult to win. The bar for a repudiatory breach is high, and employers who follow fair procedures will often be protected. For employers, it demonstrates the value of a robust grievance process – even if the employee disagrees with the outcome, a reasonable investigation can defeat a claim. The key is to act promptly, impartially, and to give the employee a fair hearing at every stage.
