    • At the end of the plan, Health NZ determined that the issues had not been resolved and dismissed her for serious misconduct.

    • The Court had to decide if Ms Yang was properly informed about the risks, whether she had a genuine opportunity to mitigate her losses, and whether reinstatement was practicable given ongoing competency concerns and supervision requirements in a safety-sensitive workplace.

    • Reinstatement was declined due to practical difficulties and ongoing competency concerns.

The story

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.

Key takeaways

  • Employers must clearly communicate performance concerns and risks.
  • Supported training plans should be documented and transparent.
  • Dismissal decisions must follow fair process and allow mitigation.
  • Reinstatement may not be practicable in safety-sensitive roles with ongoing competency issues.
  • Courts will assess compensation and lost wages based on fairness and communication.

What the Court decided

The Employment Court reviewed the Authority’s findings and Ms Yang’s challenge. The Court agreed that Ms Yang had been unjustifiably dismissed and disadvantaged, but focused on whether reinstatement was practicable and how compensation should be calculated.

The Court found that reinstatement was not reasonable due to ongoing competency concerns and the requirement for Ms Yang to work under supervision. It increased lost wages to three months and reduced compensation for hurt and humiliation by only five percent, finding Ms Yang was not properly informed about the risks and could not reasonably mitigate her losses.

Practical checks for employers

Employers should ensure that any performance management process is clear, fair, and well documented. Supported training plans must specify expectations, supervision arrangements, and feedback mechanisms. Employees should be informed about the consequences of failing to meet standards, including the risk of dismissal.

If dismissal is considered, employers must give employees a genuine opportunity to improve and mitigate losses. Communication should be direct and documented, especially in safety-sensitive roles where ongoing supervision or competency issues may affect reinstatement.

How to read this for your business

This case is especially relevant for businesses in regulated or safety-sensitive sectors. If you manage staff whose roles require accreditation or ongoing competency, you must be proactive in addressing performance issues and documenting all steps.

Dismissal should not be a surprise. Employees must understand the risks and have a fair chance to respond. If you are considering restructuring or changing roles, ensure new requirements are communicated and support is provided. Courts will look at whether employees were blindsided and whether mitigation of loss was possible.
