The legal issue
The tribunal had to decide whether the claimant was constructively unfairly dismissed, subjected to whistleblowing detriment, or suffered unauthorised deductions from wages. It also considered whether the whistleblowing detriment claims were brought within the statutory time limit.
The outcome
The tribunal dismissed all claims brought by the sales advisor against EE Ltd.
- Whistleblowing detriment: The claims were out of time, as most alleged acts occurred before 27 March 2021, and the tribunal declined to extend time.
- Constructive unfair dismissal: The tribunal found no fundamental breach of contract. The grievance process was thorough and fair, and the reduction in hours was agreed. The 'last straw' did not amount to a repudiatory breach.
- Unauthorised deductions and Working Time Regulations claims: These were also dismissed as the hours reduction was agreed and no unlawful deductions were proven.
Lessons & takeaways
- If you believe you have been subjected to detriment for whistleblowing, you must bring a claim within three months of the act – delays can be fatal even if the overall treatment is ongoing.
- A constructive dismissal claim requires a fundamental breach of contract by the employer; a thorough and fair grievance process can help the employer show it did not breach trust and confidence.
- Agreeing to a change in working hours, even under pressure, may later be treated as consent – get any changes in writing and seek advice if you feel coerced.
- Making a protected disclosure does not automatically protect you from all subsequent treatment – the employer's response must be assessed on its merits.
- If you resign, ensure you do so promptly after the alleged 'last straw' – delay may be seen as affirming the contract and waiving the breach.
A whistleblowing claim that unravelled on procedure
This case shows how even serious allegations of fraud and harassment may not succeed if the employer follows a proper process. The sales advisor, who had worked for EE Ltd for nearly four years, made three protected disclosures between August 2019 and February 2021, reporting concerns about indecent exposure, drug use, sexual coercion, and fraud. She later submitted a 10-page grievance and resigned in July 2021, claiming constructive dismissal.
What the employer did right
The tribunal found that EE Ltd's grievance process was thorough and fair. The grievance was investigated, partially upheld, and the claimant was given a detailed outcome. The tribunal noted that the claimant's allegations were not substantiated, and the employer had not acted in a way that destroyed trust and confidence. The reduction in the claimant's hours from 30 to 18 per week in September 2018 was found to have been agreed, not imposed.
Why the claims failed
Most of the whistleblowing detriment claims were out of time – the alleged acts occurred before 27 March 2021, and the tribunal declined to extend the time limit. On constructive dismissal, the tribunal found no repudiatory breach: the 'last straw' relied on by the claimant did not, when viewed in context, amount to a fundamental breach. The claimant had also continued working for some time after the alleged acts, which suggested she had affirmed the contract.
What this means for similar claims
Employees considering a constructive dismissal claim should act quickly and ensure they can point to a clear, serious breach by the employer. A well-handled grievance process can be a strong defence for employers. For whistleblowing claims, time limits are strict – waiting too long, even if the treatment is ongoing, can bar the claim entirely.
