Amendment hearing
The tribunal allowed the amendment to add indirect sex discrimination claim.
The legal issue
Whether the claimant should be permitted to amend her claim to add a new legal label (indirect sex discrimination) based on facts already pleaded, and whether the delay in applying was justified.
The outcome
The tribunal granted the claimant's application to amend her claim to include indirect sex discrimination.
The key reasons were:
- The facts supporting the claim were already in the original chronology (refusal of flexible working, childcare responsibilities, single parent status).
- The amendment was a relabelling exercise, not a new set of facts.
- The respondent had been aware of the underlying facts since August 2021.
- The claimant, as a litigant in person, had only recently obtained detailed legal advice.
No compensation was awarded at this stage as the amendment was procedural.
Lessons & takeaways
- If you are a litigant in person, ensure your initial claim form includes all relevant facts, even if you don't know the legal labels.
- Employers should be aware that refusing flexible working to a single parent during school closures may give rise to indirect sex discrimination claims.
- Tribunals are more likely to allow late amendments if the new claim is a relabelling of existing facts and the other party is not prejudiced.
What this case shows
This case highlights how a claimant who initially filed a claim without a specific legal label can later add that label if the underlying facts are already present. The former employee, a single parent, had requested flexible hours due to home-schooling pressures during the pandemic. When her employer refused, she brought claims for constructive unfair dismissal, race and disability discrimination, but did not initially mention sex discrimination. However, her chronology included details about her childcare responsibilities and the refusal of flexible working.
The tribunal allowed her to amend her claim to include indirect sex discrimination, treating it as a relabelling exercise. The judge noted that the 'childcare disparity' is so well-known that it can be judicially noticed, meaning the claimant did not need to explicitly state that women are disproportionately affected.
What the employer could have done differently
The London Borough of Bexley could have avoided this by granting the flexible working request or by engaging more constructively. Instead, they offered only a temporary two-week arrangement, which did not address the claimant's ongoing needs. Employers facing similar requests should consider whether a refusal might disproportionately impact women with childcare responsibilities, especially during exceptional circumstances like school closures.
Why this matters
For employees, this case is a reminder to include all relevant facts in your initial claim, even if you are unsure of the legal categories. For employers, it underscores that refusing flexible working to a single parent during a pandemic can lead to a sex discrimination claim, even if the employee initially frames it differently. The decision also shows that tribunals will take a pragmatic approach to amendments where the respondent has been aware of the facts from the outset.
