Inherent Requirements Of The Job: Employer’s Guide In Australia

Hiring well and managing fairly are two of the biggest levers for a productive, compliant workplace. One concept sits at the centre of many HR decisions in Australia: the inherent requirements of the job.

You’ll see this phrase pop up in recruitment, return-to-work planning, performance management and termination decisions. It’s also a key concept under the Fair Work Act and anti‑discrimination laws.

In this guide, we break down what “inherent requirements” actually means, how it interacts with your legal obligations, and the steps you can take to document roles, support your team and reduce risk. Our aim is to give you a practical, plain‑English roadmap you can apply in any workplace.

What Are The Inherent Requirements Of A Job?

Inherent requirements are the essential tasks or outcomes that are necessary to perform a particular role. They’re the core parts of a job without which the position can’t be effectively done.

Think of the job’s purpose and “non‑negotiables.” For example, operating a commercial vehicle safely and holding a valid licence are inherent requirements for a delivery driver. For a childcare educator, supervising children and maintaining required clearances are core to the role. For a developer in a small team, producing clean code to agreed standards may be an inherent outcome even if the tools or methods are flexible.

Importantly, inherent requirements are shaped by more than your job description. Industry standards, safety obligations and legal requirements all matter. When assessing a role, look at:

• The core purpose of the job (why the position exists).
• Essential outcomes the role must achieve (not just preferred skills).
• Legal or credential requirements (licences, registrations, clearances).
• Physical, cognitive or availability requirements that are genuinely necessary.
• Safety and regulatory context (e.g. high‑risk environments, child safety, food handling).

Defining these elements clearly helps you recruit fairly, make reasonable adjustments for injuries or disability, and manage performance or capacity issues with a consistent benchmark.

Why Do Inherent Requirements Matter For Employers?

Getting the inherent requirements right makes a real difference across the employment lifecycle:

• Fair recruitment: You can set selection criteria that are relevant and justifiable, lowering discrimination risk.
• Reasonable adjustments: You’ll know what can be adjusted without altering the essential nature of the role.
• Performance and capacity: Clear benchmarks support performance management, redeployment and, if needed, lawful termination.
• Compliance: Many legal tests refer back to whether an employee can perform the inherent requirements (with reasonable adjustments).

For practical management, it also makes conversations easier. When everyone understands the essential outcomes of a role, it’s easier to agree on adjustments, timeframes and next steps.

How Do Inherent Requirements Interact With The Law?

The concept runs through several parts of Australian employment law. The key is to apply it consistently, consult meaningfully and avoid jumping to conclusions.

Unfair Dismissal And Capacity To Perform

In unfair dismissal matters, the Fair Work Commission considers whether there was a valid reason related to the person’s capacity or conduct and whether a fair process was followed. If an employee can no longer perform the inherent requirements of their role (after considering reasonable adjustments), capacity may be a valid reason-but it’s not the whole story. Process still matters.

As part of that process, give the employee clear information about concerns, an opportunity to respond, and consider alternatives like adjustments or redeployment. For a deeper look at these procedural factors, see the analysis of section 387 of the Fair Work Act.

Temporary Absence Protections (Fair Work Act s 352)

It’s critical to understand the protections around illness and injury. Under the Fair Work Act, an employee is protected from dismissal because of a temporary absence due to illness or injury (with supporting evidence, and subject to the Fair Work Regulations). Broadly, this protection applies for certain periods (often discussed in terms of “up to three months” or a total of more than three months over 12 months), but the details can be technical.

Even if the protection no longer applies, other laws still do (e.g. discrimination and general protections), and a dismissal still needs a valid reason and a fair process. In short: don’t terminate simply because someone is unwell. Consider medical evidence, adjustments and timeframes, and take advice early.

Consultation And Redeployment Obligations

When changes affect a role’s viability (for example, due to restructuring or capacity issues), you may have consultation obligations under a Modern Award or enterprise agreement. If a role becomes redundant, you also need to consider whether redeployment to a suitable alternative role is reasonable before ending employment.

If redundancy is genuinely on the table, take care to map entitlements and timing correctly. Our practical guide on how to calculate redundancy payments explains the typical components and common pitfalls.

Medical Evidence And Fitness For Work

When capacity is unclear, it’s reasonable to seek medical information that is narrowly tailored to the inherent requirements. Focus on functional capacity rather than diagnosis where possible, and consult with the employee about what information is needed and why.

If you’re unsure about when and how to ask for medical information or fitness-for-work assessments, this guide to requesting medical clearance to return to work outlines good practice and compliance tips.

How To Identify And Document Inherent Requirements

A structured approach helps you get objective, defensible outcomes.

1. Define the role’s purpose. Start with why the role exists. What business need does it meet? What outcomes must be delivered?
2. List essential outcomes and tasks. Identify the “must do” tasks or results. Separate them from duties that are useful but non‑essential or can be reallocated.
3. Capture legal and industry requirements. Note any licences, registrations, clearances, accreditation or safety requirements that are mandatory for the role.
4. Assess the environment and risks. Consider location, hours, travel, exposure to hazards, client contact, or security needs that are genuinely necessary.
5. Consult stakeholders. Check with supervisors, WHS representatives and HR about what’s truly essential. Avoid embedding preferences as “inherent.”
6. Write it down. Update the position description to reflect inherent requirements, and keep it attached to the relevant Employment Contract.
7. Review periodically. Roles evolve. Reassess and update inherent requirements when technology, structure or safety obligations change.

Good documentation makes recruitment fairer and simplifies return‑to‑work and performance conversations later on.

Reasonable Adjustments, Safety And Privacy

Defining inherent requirements goes hand‑in‑hand with reasonable adjustments, WHS duties and privacy considerations.

Reasonable Adjustments And Unjustifiable Hardship

Under disability discrimination laws, employers must make reasonable adjustments to help a person perform the job’s inherent requirements. Adjustments might include modified duties or hours, assistive tech, changes to work methods or additional breaks.

You don’t need to make adjustments that would cause unjustifiable hardship or that would fundamentally change the role’s essential nature. Always consult the employee, consider medical input and document what you considered and why.

Work Health And Safety (WHS)

Your WHS duty sits alongside anti‑discrimination obligations. If a particular task or condition is a genuine safety requirement, it can form part of the inherent requirements. Be careful to base safety decisions on risk assessments and evidence-not assumptions. Where risk can be controlled through adjustments, consider those first.

Privacy And The Employee Records Exemption

Employers often handle sensitive health information when assessing capacity. In the private sector, the Privacy Act includes an “employee records” exemption for personal information directly related to current or former employment. However, it doesn’t cover everything and doesn’t remove your obligations to handle information securely and on a need‑to‑know basis. It also doesn’t apply to job candidates (pre‑employment information isn’t an “employee record”).

Practical steps include limiting the scope of information you request, keeping it confidential, and aligning your processes with your Privacy Policy.

Practical Scenarios And A Fair, Defensible Process

Capacity cases are rarely black and white. A fair, step‑by‑step process will help you reach the right outcome and reduce legal risk.

A Cautious Scenario (Not A One‑Size‑Fits‑All)

Imagine an employee in a physically demanding role who suffers a non‑work injury. They provide medical certificates and engage in discussions. You explore temporary adjustments (reduced lifting, altered roster) and trial alternative duties. You obtain functional capacity information focused on the role’s inherent requirements.

If, after genuine consultation and reasonable adjustments, the medical evidence supports that the person can’t perform the role’s inherent requirements, you’ve considered redeployment, and any temporary absence protections and consultation duties have been observed, ending employment may be open to you. Whether it’s lawful will still depend on the facts and your process.

Key point: avoid “overly definitive” decisions. The same injury can affect different roles in different ways. Take advice early and tailor your steps to the circumstances.

Process Tips You Can Apply Now

• Anchor every discussion to the documented inherent requirements, not preferences.
• Consult early and often. Invite the employee’s input on workable adjustments and timeframes.
• Seek targeted medical information about functional capacity. Avoid unnecessary health details.
• Trial and review adjustments where feasible, and document what worked and what didn’t.
• Check any Award or agreement consultation obligations and consider redeployment options.
• Assess temporary absence protections before taking adverse action.
• If termination is contemplated, ensure a valid reason, a fair process, and sound documentation from end to end.

Documents And Policies That Support Compliance

Clear documents help set expectations and show that your decisions are anchored to objective role requirements and fair processes.

• Employment Contract: Sets duties, reporting lines, hours and references to the position description with inherent requirements.
• Staff Handbook and workplace policies: Outline WHS, equal opportunity, reasonable adjustments, and return‑to‑work procedures.
• Position description: A living document that captures the role’s purpose, essential outcomes and credentials (attach to the contract and update as roles evolve).
• Performance management process: A clear framework for addressing underperformance or incapacity, including consultation and review milestones.
• Privacy Policy and data handling procedures: Explain how medical and other sensitive information is collected, used and stored.
• Fit‑for‑work and return‑to‑work procedures: Practical steps for collecting medical evidence, making adjustments and reviewing capacity over time.
• Redundancy and redeployment materials: If organisational changes affect roles, plan consultation and, where relevant, map entitlements with care-see our guide on redundancy payments.

Well‑drafted documents don’t just reduce legal risk-they also build trust by showing staff that you manage health, safety and inclusion consistently and respectfully.

Key Takeaways

• Inherent requirements are the essential outcomes and tasks a role must deliver, shaped by purpose, safety and legal obligations-not preferences.
• Documenting inherent requirements supports fair hiring, reasonable adjustments, performance management and defensible decisions.
• Before ending employment for incapacity, consider reasonable adjustments, temporary absence protections, consultation duties and redeployment options, and follow a fair process aligned with section 387 factors.
• Seek targeted medical evidence focused on functional capacity, and handle health information carefully within your Privacy Policy and the employee records framework.
• Strong foundations-an up‑to‑date position description, a clear Employment Contract, practical policies and consistent records-make hard decisions easier and reduce risk.
