Ms Yang worked as a scientist in Whāngarei Hospital’s laboratory, which is subject to strict accreditation requirements. In 2020, the laboratory faced accreditation risks, prompting a restructuring. Ms Yang moved into Microbiology, a demanding area operating around the clock.
After ongoing concerns about her competency, Ms Yang was placed on a six-month supported training plan. The plan involved supervision, feedback, and training, but at the end of the period, Health NZ decided the issues had not been resolved. Ms Yang was dismissed for serious misconduct. She filed a personal grievance, seeking reinstatement and compensation for lost wages and humiliation.
