The outcome

The tribunal dismissed all claims against Atalian Servest Limited and the individual respondents.

  • The tribunal found that the incidents complained of were routine workplace disputes and not related to the claimant's Romanian nationality.
  • The grievance process was ongoing at the time of resignation, and the employer had not acted in a way that fundamentally breached the contract.
  • No compensation was awarded as all claims failed.

Lessons & takeaways

  • Resigning before a grievance is concluded can weaken a constructive dismissal claim, as the employer may still be addressing the issue.
  • To succeed in a discrimination claim, there must be evidence linking the treatment to a protected characteristic like race or nationality.
  • Routine workplace disputes, without evidence of discriminatory motive, are unlikely to amount to unlawful harassment or constructive dismissal.
  • Employers should ensure grievances are handled promptly and fairly, but a short delay may not be a fundamental breach of contract.

This case shows the difficulty of proving that workplace conflicts are driven by discrimination rather than ordinary tensions. The claimant, a cleaner of Romanian nationality with two years' service, alleged that her supervisor bullied her by giving her the heaviest jobs and shouting at her. She resigned after a grievance meeting was cancelled, claiming constructive dismissal.

What the tribunal found

The tribunal accepted that there were disputes between the claimant and her supervisor, but concluded these were routine disagreements about work allocation and conduct, not acts of race discrimination or harassment. The claimant had not provided evidence that her Romanian nationality was a factor in how she was treated. The grievance process was still active when she resigned, and the employer had not committed a fundamental breach of contract that would justify resignation.

What could have been done differently

The employer could have proceeded with the grievance meeting sooner, but the short delay (a few days) was not unreasonable. For the claimant, waiting for the grievance outcome or raising concerns more formally might have provided a clearer basis for a claim if the employer had failed to act. The tribunal noted that the claimant's own conduct, such as taking unauthorised breaks, contributed to the tensions.

Why this matters

This case is a reminder that not all workplace friction amounts to discrimination or constructive dismissal. Employees considering resignation should first exhaust internal procedures, and ensure they can point to a clear breach of contract or discriminatory motive. Employers should handle grievances promptly but will not necessarily be penalised for minor delays if the overall process is reasonable.
