OCO v ZUA [2025] NZERA 790

This page summarises and embeds an Employment Relations Authority (ERA) determination. It is not legal advice.

Story in plain English

This was an anonymised constructive dismissal case. OCO complained that another driver had threatened him. ZUA investigated that complaint, but then suspended OCO as well on the basis that he was supposedly trying to manipulate the investigation. The Authority found there was no proper basis for that suspension.

The Authority also found that ZUA acted unfairly when it told OCO there was not sufficient evidence to uphold his complaint, when the real position was that the investigator had accepted what unnamed staff members had said. ZUA then started a disciplinary process against OCO while refusing to identify the complainants or properly set out the allegations. The Authority held those steps were serious process failures. They materially contributed to OCO's resignation and made resignation a reasonably foreseeable result, so the Authority found constructive dismissal and awarded reimbursement and compensation.

Key case markers

• This is an anonymised Christchurch ERA determination.
• The Authority member was Philip Cheyne.
• There had been an earlier preliminary determination granting leave to raise the grievance out of time.
• The Authority did not accept every criticism made by OCO, but it did accept the critical complaints about suspension, complaint handling, and disciplinary fairness.
• No contributory conduct was found against OCO.

Key events described

• OCO had worked for ZUA from late 2017 and had ongoing shoulder injury and ACC-related work issues from 2020 onward.
• On 5 November 2022 OCO complained that another driver had threatened him.
• ZUA suspended that other driver and started an investigation into OCO's complaint.
• On 8 November 2022 ZUA suspended OCO, alleging he was trying to manipulate the investigation.
• On 21 November 2022 ZUA told OCO there was not sufficient evidence to sustain his complaint and treated the complaint investigation as closed.
• In the same 21 November 2022 correspondence ZUA began a disciplinary process against OCO based in part on allegations from unnamed employees.
• OCO resigned on 22 November 2022.

Decision markers

• The Authority found ZUA's investigation into OCO's complaint was timely and not rushed.
• The explanation given for closing OCO's complaint was misleading and unfair.
• The messages relied on by ZUA did not provide any substantive ground to suspend OCO for supposedly manipulating the investigation.
• The suspension decision and the way it was made were not actions a fair and reasonable employer could have taken in the circumstances.
• ZUA was entitled to raise concern about OCO's reported statement that he would set himself and ZUA on fire, and about practical separation issues in the workplace.
• But a fair inquiry into serious allegations required timely full and fair disclosure of the material case against OCO, including generally the identity of complainants. ZUA's refusal to provide that information was a significant breach of obligation.
• The unfair suspension, unfair closure of the complaint, and unfair disciplinary process were material factors in OCO's resignation and made resignation reasonably foreseeable.
• The Authority found OCO was constructively dismissed and that ZUA had not justified the dismissal.

Orders and payments mentioned

• Reimbursement: $11,868.84 gross under s 123(1)(b) of the Employment Relations Act 2000.
• Compensation: $30,000.00 under s 123(1)(c)(i) of the Employment Relations Act 2000.
• Payment timeframe: Within 28 days of the determination.
• Costs: Reserved.

Note: the reimbursement figure was calculated by comparing OCO's usual fortnightly remuneration with the ACC earnings related compensation he received after termination, and the Authority limited recovery to the period proved on the evidence through to 31 March 2023.

Practical takeaways

• An employer cannot fairly suspend an employee on a weak or invented basis and then expect that step to disappear from the legal analysis.
• If an employer rejects an employee complaint, it needs to explain the outcome honestly and fairly.
• Where serious disciplinary allegations are raised, fair process usually requires timely full and fair disclosure of the case to be met, including complainant identities unless there is a proper basis not to disclose them.
• A resignation can still amount to constructive dismissal even if the resignation email itself is brief or refers to other pressures.
• Where emotional harm overlaps with ACC-covered injury consequences, the Authority may confine compensation to the harm properly attributable to the personal grievance itself.
