Under the Equality Act 2010, a person is considered to be disabled if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities. “Substantial” means more than minor or trivial, and “long term” usually requires that the effect has lasted or is likely to last at least 12 months. In the recent case of Stedman v Haven Leisure Ltd, the Employment Appeal Tribunal (EAT) has provided guidance on applying this definition to a neurodivergent claimant.
