Lisa O’Hara, a 36-year-old former zookeeper at Edinburgh Zoo, has lost her bid for compensation after claiming that her ADHD hindered her ability to identify monkey breeds, which led to her resignation in February 2025. O’Hara worked in sections of the zoo that included squirrel and capuchin monkeys but struggled with her probationary training, alleging she faced 'degrading' treatment and was excluded from her team. During a 12-day tribunal hearing, she described feeling ostracized and criticized for her timekeeping, while also raising concerns about health and safety practices at the zoo. However, employment judge Brian Campbell ruled that O’Hara failed to prove her claims, stating that while her health was negatively affected, the zoo and its management were not legally liable. The Royal Zoological Society of Scotland expressed satisfaction with the tribunal's decision, highlighting the importance of animal identification in zookeeping.
