Ms Yoon, a migrant worker, was employed as an office manager by MGK Homes Ltd, a construction company in Tauranga. Her employment was tied to her work visa, which depended on her working for MGK. After a payment error and changes in staffing, a meeting on 12 May 2020 led to the end of her employment. MGK claimed it was a mutual agreement, but Ms Yoon argued she was dismissed without justification.
Ms Yoon later raised a personal grievance, seeking compensation for lost wages and costs incurred due to her visa being affected. The dispute centred on whether the dismissal was justified and whether she acted within the legal timeframe.
