When an employee is unwell for a long period, employers often feel stuck.
You want to support the person, keep the role functioning, and comply with your legal obligations — but you’re also trying to run a business.
Across New Zealand and Australia, the concept of medical incapacity allows employers to make decisions about employment where long-term illness or injury prevents the employee from safely or effectively performing their role.
But medical incapacity is not simple.
Handled poorly, it creates:
- discrimination risk,
- unfair dismissal claims,
- breach of good-faith obligations,
- significant emotional harm,
- reputational damage,
- workplace tension,
- safety issues.
Handled well, it is fair, transparent, kind — and fully compliant.
Here’s your HR Unlocked guide to managing medical incapacity safely, lawfully and with humanity.
1. Medical incapacity: what it actually means (plain English)
Medical incapacity is NOT:
- firing someone because they’re sick,
- losing patience,
- personal disappointment,
- a quick fix for absenteeism,
- punishment for illness.
Medical incapacity is:
A fair-process decision made when an employee can no longer perform the role safely or effectively, and no reasonable adjustments or alternative options exist.
It is always the last resort.
2. Key legal principles (NZ + AU)
New Zealand
Employers must follow:
- good-faith under the Employment Relations Act,
- natural justice,
- anti-discrimination laws (Human Rights Act),
- reasonable accommodation obligations,
- consultation requirements.
Australia
Employers must comply with:
- Fair Work Act,
- disability discrimination laws,
- WHS laws (psychosocial risk included),
- obligations to consider reasonable adjustments,
- procedural fairness.
In both jurisdictions, failure to follow proper process is high-risk — even if incapacity is genuine.
3. The biggest mistake employers make: moving too fast or too slow
Too fast:
- terminating without proper information,
- assuming incapacity based on assumptions,
- not considering adjustments,
- ignoring medical advice,
- bypassing consultation.
Too slow:
- avoiding difficult conversations,
- never requesting medical information,
- allowing indefinite uncertainty,
- harming team morale,
- creating operational strain.
The answer is the middle ground: structured, supported, fair process.
4. Step 1: Start with welfare and support, not termination
Your first step is always a welfare meeting.
Purpose:
- check in,
- understand current health status,
- explore support needs,
- signal partnership,
- begin clarifying work capacity.
A safe script:
“We want to understand how you’re doing and how we can support you. This isn’t disciplinary — it’s about your wellbeing and clarity.”
This builds trust and sets the right tone.
5. Step 2: Request medical information properly
You need accurate, job-specific medical advice.
Ask:
- What tasks can the employee safely perform?
- What tasks can they not perform?
- What restrictions or adjustments are required?
- How long is recovery likely to take?
- Is capacity expected to improve?
- What is the prognosis for return to normal duties?
- Are there safety risks?
Best practice:
- use a consent form,
- provide the job description,
- ask specific capacity-related questions,
- allow the employee input on the questions.
Avoid broad or intrusive questions about diagnosis.
You are assessing function, not symptoms.
6. Step 3: Explore reasonable adjustments (legally required)
You must consider adjustments such as:
- reduced hours,
- modified duties,
- flexible working,
- ergonomic changes,
- staged return plans,
- task reallocation,
- additional supervision,
- temporary redeployment.
Reasonable does NOT mean:
- unlimited,
- indefinite,
- unsafe,
- unsustainable for the business.
Adjustments must balance:
- employee wellbeing,
- WHS/HSWA obligations,
- business needs,
- team impact.
Document every option considered.
7. Step 4: Consider redeployment before incapacity
Before medical incapacity can be considered, you must fairly explore:
- alternative roles,
- temporary or permanent redeployment,
- equivalent roles,
- training for suitable positions.
This step is critical in NZ and AU.
If skipped, dismissal becomes unlawful.
8. Step 5: Move to a medical incapacity process only if:
- medical evidence shows limited or no likelihood of returning to full duties in a reasonable timeframe,
- reasonable adjustments are not viable,
- redeployment is not available,
- the role cannot be held open any longer without genuine business impact,
- consultation has occurred at every stage.
The threshold is high — and should be.
9. Step 6: Conduct a fair medical incapacity meeting
This meeting must include:
- clear explanation of concerns,
- medical evidence being relied upon,
- genuine consultation,
- an opportunity for the employee to comment,
- support person option,
- exploration of any new information,
- discussion of redeployment,
- possible outcomes (including termination).
Tone matters.
This is not disciplinary — it is a compassionate legal process.
10. Step 7: Make a balanced, evidence-based decision
You must weigh:
- medical advice,
- safety risk,
- impact on the business,
- likelihood of recovery,
- ability to wait,
- fairness to the employee,
- fairness to the team,
- operational constraints.
If termination is necessary:
- explain clearly and compassionately,
- provide notice (or payment in lieu),
- pay entitlements correctly,
- offer support (EAP, transition support),
- maintain dignity.
Handled well, even difficult outcomes feel fair.
11. Common employer mistakes (NZ + AU)
Avoid:
- confusing performance with health,
- pushing for return before medically safe,
- ignoring psychological health conditions,
- relying on Google or assumptions,
- failing to consult,
- not providing medical information to the employee,
- breaching privacy,
- allowing bias (“they’re taking advantage”),
- delaying decisions for months without explanation,
- failing to document each step.
These errors create significant legal exposure.
12. The human side: medical incapacity is emotional
Employees may feel:
- scared,
- ashamed,
- guilty,
- overwhelmed,
- anxious about income,
- afraid of judgement.
Leaders may feel:
- unsure,
- worried about fairness,
- pressured by operational needs,
- fearful of getting it wrong.
This process requires humanity.
One HR Unlocked client said:
“Your medical incapacity framework helped us balance compassion and clarity. Even though the outcome was hard, the employee told us she felt respected throughout.”
That’s what good HR looks like.
The bottom line
Medical incapacity is one of the most sensitive processes in HR — but when done properly, it is fair, lawful, kind and transparent.
Across NZ and Australia, the safest and most effective approach is to:
- start with support,
- seek accurate medical advice,
- consider adjustments,
- explore redeployment,
- consult at every stage,
- act with compassion,
- follow legal requirements,
- document everything,
- treat the employee with dignity.
Handled well, medical incapacity decisions protect people — and the organisation.
