Position Duties and Job Descriptions: Legal Considerations for Australian Employers

Position duties sound simple until a role changes, a worker pushes back, or an employment dispute lands on your desk. Many Australian employers make the same avoidable mistakes: they copy a vague job description from an old role, they list duties that do not match the award classification or salary, or they rely on a broad "other duties as directed" clause and assume that covers every future change. It usually does not.

The legal risk is not just about wording. Position duties affect pay, classification, performance management, flexibility, workplace safety and whether an employee can reasonably refuse a task. Before you sign a contract, before you hire your first worker, or before you restructure a team, you need to know what duties should be documented and how much freedom you really have to change them later. This guide explains what position duties mean in practice, what to check before you sign, where employers often get caught, and how to draft job descriptions that work in the real world.

Overview

Position duties help define what an employee is actually engaged to do, and that can affect much more than day to day task allocation. A clear, legally sensible description of duties supports the employment contract, helps with award coverage and classification, and reduces disputes when the role changes.

Employers should treat position duties as a live legal and operational issue, not just an HR template. The right approach usually balances enough detail to set expectations with enough flexibility to let the business operate.

• Make sure the written duties match the actual role the employee will perform.
• Check whether the duties affect award coverage, classification level, pay rates or entitlement assumptions.
• Decide whether the duties belong in the contract, a separate position description, or both.
• Use flexibility wording carefully, including any "reasonable directions" or "other duties" clauses.
• Review whether proposed changes are minor adjustments or a real change to the employment bargain.
• Consider workplace health and safety, licensing, training and supervision needs for the duties listed.
• Keep records of updated job descriptions, consultations and accepted role changes.

What Position Duties Means For Australian Businesses

Position duties are the tasks, functions and responsibilities an employee is engaged to perform, and they can shape the legal boundaries of the role. They are not just an internal description for recruitment.

For a startup or SME, this matters most when you are hiring quickly and expecting people to wear multiple hats. That may be commercially normal, but the contract still needs to reflect the reality of the job.

Why duties matter beyond HR paperwork

A job description often feeds into several legal questions at once. If the duties are inaccurate or overly broad, the problem can show up later in places you did not expect.

• Employment contracts: the duties help define what the employee has agreed to do and what instructions are likely to be reasonable.
• Awards and classifications: the substance of the role can affect which modern award applies and which classification level fits.
• Pay and entitlements: an employee performing higher level work may argue they were underclassified or underpaid.
• Performance management: vague duties make it harder to show that expectations were clear.
• Workplace health and safety: if the role includes physical, hazardous or specialised tasks, your training and risk controls need to match.
• Redundancy and restructure decisions: the actual duties can matter when assessing whether a role still exists or has materially changed.

This is where founders often get caught. They hire a "marketing manager" but the person mostly does admin and customer support, or they hire an "operations assistant" who is actually supervising staff and carrying higher responsibility than the title suggests.

Where position duties usually appear

Position duties may sit in more than one document. The safest structure depends on how fixed or changeable the role is.

• In the employment contract itself, where core duties are described in the body of the agreement.
• In a separate position description or job description attached to the contract.
• In workplace policies, team charters or internal role documents, although these should not override the contract.

Many employers prefer to keep the detailed duty list in a separate position description. That can make updates easier. Even so, the contract should say whether that position description forms part of the employment terms, whether it may be updated, and what limits apply.

How much detail is enough

The best drafting is specific enough to set real expectations and broad enough to allow normal business changes. A position description should usually identify the core function of the role, the main responsibilities, reporting lines, decision making authority and any special requirements.

For example, a café manager role might reasonably include staff supervision, rostering, stock control, customer service and compliance with food safety procedures. It would be risky to assume the same wording also lets you move the person into a full time marketing, logistics or head office procurement role without consent.

A useful description often includes:

• the job title and reporting line
• the primary purpose of the role
• the key duties and expected outcomes
• any supervisory or budget responsibilities
• required qualifications, licences or checks
• location and any travel requirements
• a carefully drafted flexibility statement about reasonable additional duties consistent with the role

Titles do not control the legal answer

The real work performed matters more than the label on the contract. Calling someone a coordinator, manager or consultant does not decide classification, entitlement or status by itself.

Before you classify someone as a contractor, or before you set a salary and assume the award does not matter, look closely at the actual position duties. Regulators and courts usually focus on substance over branding.

Legal Issues To Check Before You Sign

Before you sign, check whether the position duties line up with the full employment arrangement, not just the recruitment ad. The main legal risk is mismatch: duties that say one thing, while pay, classification, supervision and business expectations say another.

1. Award coverage and classification

The duties performed can affect which modern award applies and where the employee sits within that award. This matters even if your contract uses an annual salary.

A misclassified role can lead to underpayment claims, back pay exposure and confusion about hours, overtime, penalty rates and allowances. You should compare the actual duties, skill level and responsibility against the relevant award descriptors. If the position is mixed, focus on the nature of the role as a whole rather than one isolated task.

This issue often arises when a business scales and a role evolves. An employee hired to do junior admin work may later supervise staff, manage stock, handle rosters and train new workers. If the written duties never changed, the payroll settings may still reflect the old classification.

2. Contractual flexibility to change duties

You can usually direct an employee to perform duties within the scope of their role and the employment contract, but you cannot assume unlimited power to redesign the job. A broad flexibility clause helps, but it is not a blank cheque.

Clauses referring to "other duties as reasonably directed" are common and often sensible. The key word is "reasonably". A direction is more likely to be reasonable where the new tasks are:

• consistent with the employee's skills, experience and seniority
• connected to the purpose of the role
• safe, lawful and properly supervised
• not a major demotion or disguised promotion without proper adjustment
• not inconsistent with the express contract terms

If you want the power to shift duties across business units, locations or functions, that should be drafted carefully and used carefully. A material change may still require consultation or agreement, especially where it affects pay, status, hours, location or reporting lines.

3. Consultation obligations when roles change

Some modern awards and enterprise agreements include consultation obligations if an employer makes major workplace changes. That can include changes to duties, structure, technology or hours.

Consultation is not just courtesy. If an industrial instrument applies, you may need to notify affected employees, discuss the likely effects and consider their views before making the change. This becomes particularly relevant during restructures, cost cutting and role redesigns.

Even where a strict consultation term does not apply, a sensible consultation process can reduce disputes and support employee buy in.

4. Performance management and disciplinary risk

Clear position duties make performance management easier and fairer. If a business later alleges poor performance, the employee may argue they were never given a clear statement of what success looked like.

Before you start a performance process, check:

• whether the duties were communicated clearly
• whether the employee had training and resources to perform them
• whether the role changed informally without updated documentation
• whether the standards being enforced are consistent with the contract and workplace policies

A vague or outdated job description can weaken the employer's position in an unfair dismissal or general protections context.

5. Work health and safety

Position duties should reflect the actual physical, technical and psychosocial demands of the role. If the role includes manual handling, site visits, driving, remote work, lone work, customer aggression risks or use of specialised equipment, the business should not bury those realities in an overly generic job description.

When duties change, WHS controls may need to change too. Extra tasks may require new training, different supervision or updated risk assessments. A contract clause does not remove your safety obligations.

6. Licences, checks and legal prerequisites

Some duties cannot be performed lawfully unless the worker holds a licence, permit, registration or clearance. That might include drivers, forklift operators, childcare workers, security staff, health professionals or responsible service roles.

If those duties are part of the role, the contract and position description should state that requirement clearly. It should also deal with what happens if the worker loses the necessary qualification or check.

7. Employee versus contractor risk

Position duties can also shed light on worker status. If a worker performs an ongoing role integrated into your business, follows your systems, reports to your managers and carries out duties much like an employee, calling them a contractor may not fix the underlying risk.

Before you accept the provider's standard terms or issue a freelance agreement, think about the real duties, control and day to day working arrangement. Misclassification can have significant consequences.

Common Mistakes With Position Duties

The most common mistake is treating position duties as an afterthought. Employers often focus on salary and start date, then recycle a generic duty list that does not fit the business.

Using descriptions that are too vague

Words like "assist with operations" or "support business needs" are not always wrong, but they are not enough on their own. If everything is broad, it becomes harder to prove what the role actually required.

This creates problems when:

• you want to manage underperformance
• the employee says a task falls outside the role
• you need to assess award classification
• another manager starts assigning inconsistent work

Making the role so broad it stops being credible

Some employers overcorrect and draft a job description that says the employee can do virtually anything in the business. That approach often looks flexible, but it can be legally weak and commercially unhelpful.

If the role is described as including every possible task, the employee may argue the clause is uncertain or the later direction is unreasonable. Team leaders also lose clarity about what the employee is really accountable for.

Failing to update duties after promotion or restructure

A role can change slowly and still become legally significant. A startup's first operations hire may take on recruiting, procurement, payroll coordination and team supervision over twelve months. If the contract and position description still describe an entry level support role, the documents are no longer reflecting reality.

This can affect classification, remuneration, bonus structures, restraint clauses and notice expectations. Review duties when someone is promoted, moved, or given sustained higher level responsibility.

Relying too heavily on "other duties as directed"

That phrase is useful, but only when used properly. It usually helps with incidental or related duties, not a fundamental rewrite of the role.

For example, asking a retail supervisor to help with stocktake is likely to be reasonable. Directing the same employee to perform a substantially different technical role without training, consultation or pay review is a different issue.

Ignoring the award consequences of actual duties

A title does not protect you from an underpayment claim. If the real position duties fit a higher classification, the employee may be entitled to different pay and conditions.

This often arises in hospitality, retail, admin and trades related businesses where team members start supervising others or take on specialised responsibilities without formal role updates.

Forgetting location, travel and hybrid work expectations

Position duties are not only about tasks. They can also intersect with where and how the work is performed. If the role requires travel between sites, client visits, warehouse work and home based admin, your documents should say so.

Without that clarity, disputes can arise when an employee resists travel, refuses a site transfer, or objects to a changed work pattern.

Not separating essential duties from occasional tasks

A practical job description distinguishes the core purpose of the role from less frequent or incidental duties. That makes recruitment, probation reviews and performance conversations much easier.

It also helps if the employee later says a particular duty was never a real part of the job. Essential duties should be obvious from the document.

Overlooking accessibility and discrimination issues

Some duties are genuinely inherent requirements of the role. Others are habits, preferences or legacy practices. That distinction matters when dealing with discrimination, flexible work requests and reasonable adjustments.

Before you insist that every listed task is mandatory, ask whether it is truly inherent to the role. If not, there may be room to adjust duties without changing the core job.

FAQs

Should position duties be in the employment contract or a separate job description?

Usually both, in a practical way. The contract should define the role and include flexibility language, while a separate position description can list detailed duties that are easier to update.

Can an employer change an employee's duties without consent?

Sometimes, but only within limits. Minor or related changes are often permitted if they are reasonable and consistent with the contract, while major changes to the nature of the role may require consultation or agreement.

Does a job title decide the employee's award classification?

No. The actual work performed, level of skill and responsibility usually matter more than the title.

What if an employee refuses to do a task not listed in their job description?

The answer depends on whether the task is a lawful and reasonable direction connected to the role. A task can still be required even if it is not listed word for word, but the further it sits from the agreed role, the more risk there is in forcing the issue.

How often should employers review position duties?

Review them when you hire, at the end of probation, after promotions, after restructures and whenever the role has materially changed in practice. Annual reviews can also help catch role drift before it becomes a legal problem.
