Decision snapshot

  1. What happened

    • LMN was employed by STC, a school board, and raised 22 separate complaints about her treatment at work.
    • She alleged the board failed to provide a safe workplace, did not support her induction or training, mishandled student records, and did not take her health and safety seriously.
    • LMN also claimed the board breached her privacy by contacting her past principals and references without her consent, and by discussing her return to work with her GP.
    • Another key issue was that the board failed to acknowledge her medical certificates and placed her on leave without pay instead of processing her sick leave.
  2. What the court had to decide

    • The main legal issue was whether the employer’s actions - specifically contacting references without consent and failing to process sick leave with valid medical certificates - amounted to an unjustified disadvantage and breach of the duty of good faith under the Employment Relations Act 2000.
    • The Court also considered whether a range of other alleged failures (such as induction, training, and handling of complaints) breached legal or contractual obligations or caused real disadvantage to the employee.
  3. What the court decided

    • The Employment Court found that the employer unjustifiably disadvantaged LMN by contacting her references without consent and by failing to acknowledge her medical certificates, placing her on leave without pay instead of sick leave.
    • The Court ordered compensation of $5,000 and correction of sick leave and wage entitlements.
    • All other claims were dismissed, and the employer was awarded costs due to the limited success of the employee’s case.

Practical impact

Practical read

  • LMN v STC shows that New Zealand employers must get consent before contacting employee references and must process sick leave correctly when medical certificates are provided.
  • The Court found that these failures were unjustified disadvantages, but dismissed most other complaints.
  • Employers should have clear policies for handling personal information and sick leave, train managers on privacy and employment obligations, and respond to grievances in writing.
  • Minor workplace issues or misunderstandings, without a breach of duty or real disadvantage, are unlikely to succeed as personal grievances.

Useful next steps

  • Employers must get consent before contacting employee references.
  • Medical certificates must be acknowledged and sick leave processed correctly.
  • Minor or technical issues usually do not amount to unjustified disadvantage.
  • Most workplace complaints will not succeed unless there is a real breach and harm.
  • Clear processes and good documentation help prevent and resolve disputes.

The story

LMN worked for STC, a school board, and raised a long list of complaints about her treatment at work. She said the board failed to provide a safe workplace, did not support her induction or training, mishandled student records, and did not take her health and safety seriously. LMN also claimed her privacy was breached when the board contacted her past principals and references without her consent, and when they discussed her return to work with her GP.

Another key issue was how the board handled her sick leave. LMN provided medical certificates, but the board placed her on leave without pay for some periods instead of processing her sick leave. She brought a personal grievance for unjustified disadvantage and breach of good faith, challenging an earlier decision that had dismissed her claims. The Employment Court reviewed all 22 issues she raised, but only two were upheld.

Practical sense check

  • Employee raised 22 separate complaints about treatment at work
  • Privacy breach: references contacted without consent
  • Medical certificates not acknowledged; sick leave mishandled
  • Most other complaints (bullying, exclusion, etc.) were dismissed

What the Court decided

The Employment Court found that only two of LMN’s 22 complaints amounted to an unjustified disadvantage. First, the board breached the collective agreement and the duty of good faith by contacting LMN’s past principals and references without her consent. Second, the board failed to acknowledge two medical certificates and wrongly placed LMN on leave without pay instead of sick leave for those periods.

All other claims, including those about induction, training, student records, bullying, and health and safety, were dismissed. The Court said these issues did not breach legal or contractual duties or cause real disadvantage. The Court ordered the board to pay LMN compensation and correct her sick leave entitlements, but also noted that the board was entitled to costs because most claims failed.

What the court focused on

  • Privacy breach and sick leave errors were unjustified disadvantages
  • All other complaints did not meet the threshold for a personal grievance
  • Compensation and sick leave corrections ordered
  • Employer awarded costs due to limited employee success

How to read this for your business

This case is a clear reminder for employers to respect employee privacy and follow proper processes for sick leave. Contacting references or past employers without consent is a breach of good faith and can lead to liability. Similarly, ignoring valid medical certificates and failing to process sick leave correctly can result in compensation orders.

However, the Court also made it clear that not every workplace issue will amount to a personal grievance. Employers are not expected to be perfect, but they must act in good faith and follow the law and employment agreements. Minor mistakes, misunderstandings, or issues that do not cause real harm are unlikely to succeed in court.

Practical sense check

  • Always get consent before contacting references or past employers
  • Acknowledge and process medical certificates promptly
  • Follow collective agreements and workplace policies
  • Document all employment actions and decisions
  • Address complaints seriously, but know not all will be upheld

Operating checklist for employers

To avoid similar issues, employers should have clear processes for handling employee information and sick leave. Regular training for managers and HR staff can help prevent breaches of privacy or good faith. Documenting all employment actions and decisions is also important if a dispute arises.

For example, before contacting any reference or past employer, get written consent from the employee and keep a record. When an employee provides a medical certificate, process their sick leave promptly and confirm in writing how their leave is being handled. If a grievance or complaint is raised, respond in writing and keep all correspondence. These steps help show that you are acting in good faith and following the law if your decisions are ever challenged.

Sense check

  • Get written consent before contacting references
  • Keep employee medical information confidential
  • Process sick leave as soon as a valid certificate is provided
  • Check collective agreements for specific obligations
  • Respond to grievances and complaints in writing

Common questions

What is an unjustified disadvantage in employment?

An unjustified disadvantage occurs when an employer’s actions or decisions cause real harm to an employee’s employment or conditions, and those actions are not justified by law or contract. Examples include breaching privacy, ignoring medical certificates, or failing to follow agreed processes.

Can an employer contact an employee’s references without consent?

No. In this case, the Court found that contacting references or past principals without the employee’s consent breached both the collective agreement and the duty of good faith.

What should employers do when an employee provides a medical certificate?

Employers must acknowledge valid medical certificates and process sick leave correctly. Placing an employee on leave without pay instead of approved sick leave, without good reason, can amount to an unjustified disadvantage.

Do all workplace issues amount to a personal grievance?

No. The Court made clear that only breaches of legal or contractual duties that cause real disadvantage will succeed as personal grievances. Minor issues or misunderstandings are not enough.
