The outcome

The tribunal dismissed all claims. It found that the claimant resigned after obtaining a new job, and that the employer had not breached the implied term of trust and confidence. The tribunal also found no evidence of race discrimination or harassment: the claimant's pay was the same as comparators, the skills test was applied to all candidates, the computer allocation was based on legacy hardware, and the social media posts were not related to race. No compensation was awarded.

Lessons & takeaways

  • Resigning after securing a new job, without first raising a grievance about alleged discrimination, makes it very difficult to prove constructive dismissal.
  • To succeed in a direct discrimination claim, you must show that you were treated less favourably than a comparator in materially similar circumstances.
  • Employers can defend skills tests and computer allocation decisions if they can show they were applied consistently and based on objective criteria.
  • Allegations of harassment based on social media posts require evidence that the posts were related to a protected characteristic, not just that they were offensive.

When a resignation is just that

This case shows how difficult it can be to prove constructive dismissal when an employee resigns after securing a new job. The claimant, a Part 1 Architectural Assistant with four years' service, resigned in July 2021 after being promoted to Part 2 and receiving a salary increase to £25,000. She had already accepted a new role elsewhere. The tribunal found that the employer had not breached the implied term of trust and confidence – the claimant's resignation was a free choice, not a response to any fundamental breach by the employer.

The discrimination claims: no evidence of less favourable treatment

The claimant alleged that she was paid less than white colleagues, required to do a skills test at interview, given an older computer, and subjected to tokenistic social media posts about race. However, the tribunal found that her pay was the same as other Part 1 Architectural Assistants hired around the same time. The skills test was required of all candidates interviewed in the relevant period. The older computer was legacy hardware from a previous firm, not a reflection of her race. And the social media posts – while perhaps misguided – were not shown to be related to her race.

What the employer did right

Perpetua in Perpetuum Ltd was able to point to consistent treatment of employees. The claimant never raised a grievance about discrimination or harassment during her employment. The tribunal noted that the claimant's comparators were not in materially different circumstances, and that the employer's explanations for the alleged differences were credible and non-discriminatory.

Key takeaway for employees

If you believe you are being discriminated against, it is essential to raise a grievance internally before resigning. Without that, a tribunal is likely to see your resignation as voluntary rather than a response to a fundamental breach. And for discrimination claims, you need evidence of less favourable treatment compared to a real comparator in similar circumstances – not just a feeling that you were treated unfairly.
