Edgecumbe Supermarket Ltd v Petersen [2026] NZEmpC 56 - ERA unjustified dismissal finding upheld

Edgecumbe Supermarket unsuccessfully challenged the Employment Relations Authority determination in favour of Mrs Petersen. After hearing the matter afresh, the Employment Court held that the employer's conduct amounted to an unjustified dismissal and left the Authority's awards in place.

Background

Mrs Petersen worked for Edgecumbe Supermarket. A dispute arose after she raised concerns about carrying out a task. The employer immediately suspended her, required her to leave her uniform and threatened her with trespass. There was also disagreement about proposed leave and whether the employment relationship was otherwise due to continue.

Why the Court found a dismissal

The Court considered it reasonable for Mrs Petersen to understand from the employer's words and conduct that her employment had ended. The Court also found that the relevant conversation had led her reasonably to believe her leave had been approved and that her employment was continuing.

The purported suspension was not treated as a neutral holding measure. In the circumstances it amounted to an unjustified dismissal.

Contribution

The Court accepted that an employee may raise concerns about work but is expected to communicate those concerns constructively. That issue did not alter the conclusion that the dismissal was unjustified.

Why this case matters

The case is particularly useful because the employer exercised its right to a de novo challenge and the employee's ERA result survived the fresh hearing. It also illustrates that the legal character of an employer's actions depends on their objective effect: calling something a suspension will not prevent it being treated as a dismissal where the surrounding conduct reasonably communicates that the employment is over.
