The legal issue
Whether the employer's failure to handle the employee's grievance amounted to a breach of the implied term of trust and confidence, making her resignation a constructive dismissal, and whether compensation should be increased for unreasonable failure to follow the ACAS Code.
The outcome
The tribunal held that the employee was constructively and unfairly dismissed. The employer had failed to address her grievance for many months, and when it finally proposed a meeting, the arrangements were impractical because her union representative was restricted and she was unwilling to return to the place where she had experienced bullying.
Compensation was awarded as follows:
- Basic award: £1,093.50
- Compensatory award: £10,345.00 (after a 25% uplift for breach of the ACAS Code)
- Total: £11,438.50
Lessons & takeaways
- Employers must handle grievances promptly and reasonably; ignoring them can lead to a constructive dismissal claim.
- If you resign because of your employer's conduct, you must do so promptly after the last act of breach, or you may lose the right to claim.
- A 25% uplift in compensation can be applied if the employer unreasonably fails to follow the ACAS Code of Practice on disciplinary and grievance procedures.
- Length of service and age affect the basic award calculation; here, three years' service and age over 41 gave 1.5 weeks' pay per year.
- Representing yourself is possible, but having professional advice can help ensure all losses are properly claimed.
What this case shows
This case is a textbook example of constructive dismissal caused by poor grievance handling. The employee had been off sick for nearly two years when she raised a grievance. Instead of dealing with it, the employer left her waiting for months. By the time they offered a meeting, the arrangements were unworkable – her union rep was restricted, and she was expected to return to the very place where she said she had been bullied. She resigned, and the tribunal agreed that the employer had destroyed the trust and confidence needed for the employment relationship.
What the employer could have done differently
The employer's key mistake was delay. A grievance should be investigated and responded to within a reasonable time. Here, the employee waited so long that when a meeting was finally proposed, it was too little, too late. The employer also failed to consider alternatives – such as holding the meeting at a neutral venue or allowing a different representative. A prompt, fair process might have avoided the resignation and the claim.
Why this matters
The case also shows the importance of the ACAS Code of Practice. Because the employer ignored the grievance without reasonable cause, the tribunal increased the compensatory award by 25%. This uplift is designed to encourage employers to follow proper procedures. For employees, it means that if your employer unreasonably fails to handle a grievance or disciplinary matter, you may be entitled to extra compensation.
The compensation
The tribunal awarded a basic award of £1,093.50 (based on three years' service and age over 41) and a compensatory award of £10,345.00, which included the 25% uplift. The total of £11,438.50 reflects the employee's actual financial losses, but the tribunal did not award anything for injury to feelings as no separate claim was pursued.
