Case Summary

A preliminary hearing to determine whether the claimant was disabled within the meaning of the Equality Act 2010. The claimant suffered from stress and anxiety arising from work-related pressures from November 2023 to February 2025. The tribunal found that the claimant had a mental impairment with substantial adverse effects on normal day-to-day activities (including sleep difficulties, concentration problems, and social withdrawal) that was long-term in nature.

Why this outcome?

The tribunal found that the claimant had a mental impairment (stress and anxiety) supported by contemporaneous medical records from November 2023 onwards. The impairment had substantial adverse effects on normal day-to-day activities including significant sleep difficulties, concentration problems, and social withdrawal. The adverse effect was long-term as it lasted from November 2023 to February 2025 and was likely to recur based on the evidence available at the material time.
