Can Your Employer Change Your Job Description Without Consent? (2026 Guide)
Learn when your employer can legally change your job duties in Australia and when changes cross the line into redundancy or constructive dismissal. Your 2026 guide to workplace rights.
Can Employers Change Your Job Duties? The General Rule
The short answer is: it depends on the nature and extent of the change. Employers have a general right to direct and control the work of their employees, which includes some flexibility to adjust duties, tasks, and responsibilities within the broad scope of the employee's role. This is sometimes called the employer's managerial prerogative. However, this right is not unlimited. The employment contract — whether written or implied — establishes the fundamental nature of the role, and the employer cannot unilaterally make changes that go beyond what was reasonably contemplated when the employee accepted the position. Minor adjustments to duties that fall within the general scope of the role are generally permissible. For example, asking an administrative assistant to learn a new software system, or asking a sales representative to cover a different territory, would typically be within the employer's rights. But asking that same administrative assistant to start working on a construction site, or requiring a senior manager to perform manual labour, would likely exceed the scope of reasonable direction. The key test is whether the direction is lawful, reasonable, and within the scope of the employment contract. A direction that is unreasonable or outside the contract is one the employee is not obliged to follow.
Reasonable Changes vs Fundamental Changes to Your Role
Courts and tribunals distinguish between reasonable changes within the scope of the role and fundamental changes that effectively alter the nature of the position. Reasonable changes include updates to processes and procedures, introduction of new technology, minor adjustments to reporting lines, reasonable reallocation of tasks within the same classification level, and changes to work methods. These are part of the normal evolution of any job and employees are generally expected to adapt. Fundamental changes, on the other hand, go to the core of the employment relationship. These include a significant reduction in seniority or status, removal of key responsibilities that defined the role, a requirement to perform work that is substantially different from what was agreed, relocation to a significantly different workplace without a mobility clause, and changes that reduce the skill level or classification of the work. The distinction often comes down to whether the role the employee is now performing is recognisably the same role they were hired for. If a marketing director is stripped of their team and budget and asked to perform data entry, the role has fundamentally changed regardless of what the employer calls it. The Federal Court has held that the character of the employment must remain substantially the same — cosmetic relabelling does not change the substance.
When a Change of Duties Amounts to Redundancy
If an employer changes your duties so significantly that your original position no longer exists in substance, this may constitute a redundancy — even if the employer does not call it one. Under section 389 of the Fair Work Act, a redundancy occurs when the employer no longer requires the person's job to be performed by anyone, or the employer becomes insolvent. The focus is on the job, not the person. If your role as a project manager is restructured so that all project management duties are distributed to other staff and you are reassigned to general administrative work, the project manager position has effectively been made redundant. You may be entitled to redundancy pay under the NES even though you have not been terminated. This is sometimes called a constructive redundancy. The employer's obligation to pay redundancy arises when the position is genuinely no longer required, regardless of whether the employee remains employed in a different capacity. If you are offered and accept an alternative position, your entitlement to redundancy pay depends on whether the new role is suitable and comparable. If the alternative role is a significant downgrade, you may be entitled to refuse it and receive your redundancy entitlements. The FWC can also reduce or eliminate redundancy pay if the employer obtains other acceptable employment for the employee.
The Implied Duty of Mutual Trust and Confidence
Australian courts have recognised an implied term of mutual trust and confidence in employment contracts, following the High Court's decision in Commonwealth Bank of Australia v Barker (2014). While the High Court stopped short of fully adopting the UK implied term, it acknowledged that employment contracts contain implied obligations of good faith and fair dealing. This implied duty is relevant to changes in job descriptions because an employer who unreasonably and significantly alters an employee's role without consultation may be acting in breach of this implied obligation. Conduct that is calculated to destroy or seriously damage the relationship of trust and confidence — such as stripping an employee of meaningful work as a form of punishment — is likely to breach this term. The implied duty does not prevent all changes, but it requires that changes be made in good faith, for legitimate business reasons, and with appropriate consultation. An employer who changes an employee's duties to marginalise them, force them to resign, or punish them for exercising a workplace right would likely be found to have breached the implied duty. If the implied term is breached, the employee may be able to claim damages for breach of contract, argue constructive dismissal if they resign in response, or in some cases, seek an injunction preventing the employer from implementing the change. Evidence of the employer's motivation and the reasonableness of the change is critical.
Constructive Dismissal and Unreasonable Changes
If an employer makes unreasonable and fundamental changes to your role without your consent, and those changes make your position intolerable, you may have grounds to claim constructive dismissal if you resign. The Fair Work Commission can treat a resignation as a dismissal under section 386(1)(b) of the Fair Work Act if the employee was forced to resign because of conduct or a course of conduct engaged in by the employer. To establish constructive dismissal based on a change of duties, you would typically need to show that the changes were fundamental in nature (not merely inconvenient), the changes were imposed unilaterally without genuine consultation, you objected to the changes and gave the employer an opportunity to remedy the situation, the employer refused to address your concerns, and resignation was the only reasonable option left. The FWC takes a high threshold approach to constructive dismissal. Mere dissatisfaction with changes is not enough — the conduct must be of such a nature that no reasonable person could be expected to continue in the role. It is crucial that you exhaust internal avenues before resigning. Raise your concerns in writing, use any grievance or dispute resolution procedures available, and give the employer a reasonable opportunity to respond. If you resign without first raising the issue, the FWC is less likely to find constructive dismissal.
Consultation Obligations When Changing Roles
Modern awards and enterprise agreements contain mandatory consultation clauses that require employers to consult with employees about major workplace changes. Under the model consultation clause (now standard in all modern awards), employers must consult about changes to the regular roster or ordinary hours of work and about major workplace changes likely to have a significant effect on employees. Major workplace changes include restructures, changes to the size or composition of the workforce, and the alteration of the nature or scope of positions. When a consultation obligation is triggered, the employer must notify affected employees of the proposed change, provide all relevant information about the change, invite employees to give their views and genuinely consider those views before making a final decision. Failure to consult is a breach of the award or agreement and can be enforced through the FWC or the courts. However, the consultation obligation is procedural — it does not give employees a veto over changes. The employer must consult genuinely, but it is not required to reach agreement. After genuine consultation, the employer may proceed with the change even if employees disagree. That said, a failure to consult can be relevant evidence in an unfair dismissal or general protections claim, as it goes to the reasonableness of the employer's conduct. Employees should always participate in consultation processes and put their concerns on record.
Practical Steps If Your Role Is Being Changed
If your employer announces changes to your role that you are concerned about, take a measured and strategic approach. First, review your employment contract carefully. Look at the position description, any clauses about duties and responsibilities, and whether there is a clause allowing the employer to direct you to perform other duties. Many contracts contain a flexibility clause such as 'and other duties as reasonably directed,' but even this clause is limited to directions that are reasonable. Second, check your applicable award or enterprise agreement for consultation obligations and dispute resolution procedures. Third, document the changes. Write down exactly what has changed — duties removed, duties added, changes to reporting lines, changes to status or seniority — and compare this to your original position description. Fourth, raise your concerns in writing with your manager or HR department. Be specific about what changes you object to and why. Ask for the business reason behind the changes. Fifth, if you are a union member, contact your union delegate or organiser for advice. Sixth, if the changes are significant and the employer will not engage, consider lodging a dispute under your award's dispute resolution clause. The FWC can conciliate and, in some cases, arbitrate the dispute. Throughout this process, continue to perform your work to the best of your ability — refusing to work is rarely advisable and may give the employer grounds for disciplinary action.
