For Australian employers, operational change is inevitable. Growth, restructures, technology, and economic pressures often require changes to employee roles and duties.
However, changing an employee’s role without following the correct legal process can expose your business to unfair dismissal claims, adverse action disputes, breach of contract claims, and civil penalties.
This employer-focused guide, prepared by our employer lawyers, explains when you can change duties, when you cannot, and how to implement change lawfully and safely under Australia’s workplace laws.
Key Takeaways
Employers may issue lawful and reasonable directions, but generally cannot unilaterally change pay, classification, or core role functions.
Awards and enterprise agreements require consultation before major workplace change or changes to regular hours or rosters.
If the original role no longer exists, redundancy obligations (not redeployment by force) may apply.
A significant reduction in duties or remuneration may legally be treated as a dismissal.
Requiring higher-level duties may trigger higher-duties pay or reclassification obligations.
When Employers Can Change Duties or Roles
1. Lawful and Reasonable Directions
Employers are entitled to manage how work is performed. You can generally direct employees to adjust tasks within their existing skill set, comply with operational requirements, attend the usual workplace and follow updated processes or systems.
To be enforceable, the request must be lawful, reasonable management action, consistent with the employment contract and any applicable modern award or enterprise agreement.
Directions that fall outside these boundaries may be refused and can escalate into disputes.
2. Changes Permitted by Contract or Industrial Instrument
Some employment contracts include flexibility clauses allowing reasonable variation of duties within a role or classification. These clauses can be useful – but they are not unlimited.
Employers must be sure that contracts do not override minimum entitlements, any changes must still comply with modern awards, enterprise agreements, and the National Employment Standards and that flexibility clauses do not authorise demotion or pay reduction.
For enterprise agreement employees, changes to terms must follow the statutory variation process and be approved by employees and the Fair Work Commission.
3. Individual Flexibility Arrangements (IFAs)
If you and an employee agree, an Individual Flexibility Arrangement can vary certain award or enterprise agreement terms.
For employers, IFAs must be genuinely agreed, be in writing, leave the employee better off overall, and not undercut minimum standards.
IFAs are particularly useful where business needs and employee preferences align.

When Employers Cannot Unilaterally Change Roles or Duties
1. Changes to Fundamental Employment Terms
Employers should not unilaterally change pay or classification level, core duties outside the role scope, regular hours or roster patterns, and work location where it causes significant detriment.
Doing so can amount to breach of contract or repudiation, allowing the employee to treat the contract as terminated.
2. Demotion and Downgrading Duties
Reducing duties, seniority, or pay (even without termination) may constitute a dismissal at law.
The Fair Work Commission assesses the practical effect of the change, not the label that employers apply. If the employee’s status or remuneration is significantly reduced, unfair dismissal exposure may arise.
3. Adverse Action Exposure
Role changes that disadvantage an employee may breach general protections laws if motivated by prohibited reasons. This is also called ‘adverse action’ and includes:
exercising workplace rights
raising workplace complaints
union involvement
discrimination on protected grounds
Legal Tip: These claims reverse the onus of proof onto the employer to prove that the change to the employee’s role was not a result of that employee exercising any workplace right. Adverse action carries serious financial and reputational risk.
4. Using Role Changes to Avoid Legal Obligations
Employers must not restructure roles to avoid fixed-term contract limits, redundancy pay or award or enterprise agreement obligations.
Anti-avoidance provisions apply, and penalties can be significant.
Consultation Obligations Employers Must Follow
All modern awards and enterprise agreements contain consultation clauses.
Before implementing major change, employers must notify affected employees, provide written information about the proposed change, discuss impacts and mitigation strategies, and genuinely consider feedback.
There is a specific statutory requirement to consult before changing regular rosters or ordinary hours. Failure to consult can invalidate the change and expose the business to claims.

Role Changes, Redundancy, and Redeployment
If, after restructure, your business no longer requires a particular role to be performed by anyone, the situation points to redundancy.
For a redundancy to be “genuine,” employers must eliminate the role, comply with consultation obligations, and consider redeployment options.
Forcing employees into materially different roles without consent can undermine the genuineness of a redundancy and lead to unfair dismissal liability.
Practical Compliance Checklist for Employers
Before changing duties or roles, employers should ask themselves:
Is the change covered by a lawful and reasonable direction?
Does the contract clearly authorise the change?
Does an award or enterprise agreement require consultation?
Will the change affect classification or pay?
Could the change be seen as a demotion or adverse action?
Is the role actually being eliminated (redundancy risk)?
Document all decisions, consultation steps, and agreements in writing.
Before implementing any changes, get employer-focused legal advice to reduce your risk of unfair dismissal, adverse action, or underpayment claims.

Frequently Asked Questions
Can I change an employee’s duties without agreement?
Only if the change is lawful, reasonable, and within the existing role and classification.
Can I reduce duties but keep pay the same?
Possibly – but significant reductions in responsibility or status may still amount to a demotion.
Do I always need to consult before making changes?
Consultation is mandatory for major workplace change and for changes to regular hours or rosters under awards and enterprise agreements.
Is moving an employee into a different role safer than redundancy?
Not necessarily. If the role no longer exists, redundancy obligations still apply.
Learn more about suitable alternative roles and reducing redundancies.
What is the biggest legal risk when changing roles?
Unilateral changes to fundamental terms without consultation or consent, which commonly lead to unfair dismissal and adverse action claims.
Prosper Law advises employers on restructures, role changes, redundancies, and compliance under the Fair Work system – If you are planning workplace change, obtaining advice early can prevent costly disputes later.
