Redundancy, it is or it isn't — Helensburgh Coal v Bartley

At its core, Helensburgh Coal Pty Ltd v Bartley & Ors is not a dispute about whether an employer may restructure its workforce. That power is well established under Australian employment law. Instead, the case turns on a narrower but more consequential legal question: when employees are dismissed as redundant, how far must an employer go to consider alternative workforce arrangements before the dismissal can lawfully be described as a “genuine redundancy”?

The High Court’s answer reshaped the practical operation of redundancy law. It confirmed that employers cannot rely on formal labels or rigid workforce boundaries where, in substance, similar work continues to be performed through contractors. The decision clarified the scope of the Fair Work Commission’s inquiry and reinforced that redundancy under the Fair Work Act is a substantive, not merely structural, concept.

Parties and Context

Helensburgh Coal Pty Ltd operated a coal mining enterprise in New South Wales. Like many employers in capital-intensive industries, it relied on a mixed workforce model, combining directly employed workers with contractors performing operational roles.

The respondents were a group of employees whose employment was terminated during a period of operational change. Helensburgh Coal characterised the dismissals as redundancies arising from reduced operational requirements. The employees accepted that restructuring was occurring but challenged whether their dismissals satisfied the statutory definition of genuine redundancy.

Central to their claim was the continued engagement of contractors performing work that, in practical terms, overlapped with work previously undertaken by employees.

The Statutory Framework

The dispute was governed by section 389 of the Fair Work Act 2009 (Cth). Under that provision, a dismissal will be a genuine redundancy only if two requirements are met.

First, the employer must no longer require the employee’s job to be performed by anyone due to changes in operational requirements.

Second, and critically in this case, it must not have been reasonable in all the circumstances for the employee to be redeployed within the employer’s enterprise or an associated entity.

If either limb is not satisfied, the dismissal is not a genuine redundancy and may be challenged as an unfair dismissal.

Proceedings in the Fair Work Commission

The dismissed employees commenced unfair dismissal proceedings in the Fair Work Commission. Helensburgh Coal argued that the statutory test was met because the employees’ specific roles no longer existed and there were no vacant employee positions available at the time of dismissal.

The Commission rejected that narrow approach. It found that, given the employer’s ongoing use of contractors, it would have been reasonable to consider whether the employees could have been redeployed into work being performed by contractors.

The Commission concluded that redeployment had not been properly explored and that the dismissals were therefore not genuine redundancies.

This conclusion did not require the Commission to determine whether the employer was obliged to eliminate contractor arrangements. Rather, it required an assessment of whether redeployment into available work, viewed realistically, was reasonable in the circumstances.

Appeals and the Central Legal Issue

Helensburgh Coal challenged the Commission’s approach, arguing that the redeployment inquiry should be confined to existing employee vacancies. It contended that requiring consideration of contractor roles impermissibly intruded into managerial prerogative and workforce design.

The Full Federal Court rejected that argument and upheld the Commission’s reasoning. The matter then proceeded to the High Court.

Before the High Court, the employer’s position was clear. It accepted that redeployment must be considered but argued that the law does not require an employer to restructure its contracting model or reconfigure its workforce to create positions for redundant employees.

The employees, by contrast, maintained that section 389 requires a practical inquiry into whether dismissal could reasonably have been avoided, including by reallocating work that continued to exist within the enterprise.

The High Court’s Decision

The High Court unanimously dismissed the appeal. The Court held that section 389 permits a broad inquiry into redeployment. The statutory language does not confine the Commission to identifying existing vacancies. Instead, it allows consideration of whether it would have been reasonable for the employer to deploy the employee differently, including by adjusting how work is allocated within the enterprise.

Importantly, the Court confirmed that contractor arrangements are not beyond scrutiny. Where work continues to be performed, the Commission may consider whether it would have been reasonable to redeploy an employee into that work, even if it is currently performed by contractors.

The Court emphasised that this does not remove managerial discretion. Employers remain free to decide how to structure their operations. However, when asserting a genuine redundancy defence, they must demonstrate that reasonable redeployment options were genuinely unavailable or unreasonable, not merely inconvenient.

Attitudes to the Law

The case exposed a clear divergence in how the parties approached statutory obligations.

Helensburgh Coal adopted a formalistic view of redundancy, focusing on job titles, contractual categories, and existing workforce structures. Its approach reflected a belief that contractor roles sat outside the redeployment inquiry.

The employees, supported by the Commission’s reasoning, advanced a purposive view of the legislation. They treated redundancy as a protection designed to prevent avoidable dismissals, not a mechanism to legitimise workforce substitution.

The High Court ultimately endorsed the latter approach, grounding its reasoning in the protective purpose of the Act.

Professional Significance

For employers, the decision sharpens the redundancy risk landscape. It confirms that workforce models involving contractors will be examined closely where employees are dismissed. Redundancy planning must include a documented and genuine assessment of whether contractor-performed work could reasonably be offered to employees.

For employees and unions, the case strengthens the capacity to challenge dismissals that occur alongside continued operational activity. It reinforces that redundancy is not determined solely by organisational charts or engagement labels.

For practitioners, the case clarifies that section 389 demands a holistic assessment. The inquiry is not whether redeployment was easy or commercially preferable, but whether it was reasonable in all the circumstances.

Conclusion

Helensburgh Coal Pty Ltd v Bartley & Ors reframes genuine redundancy as a substantive legal concept tied to real workforce outcomes. The High Court confirmed that employers cannot insulate redundancy decisions from scrutiny by relying on contractor arrangements where work continues to exist.

The decision reinforces that redundancy law operates as a safeguard against avoidable dismissal, requiring careful consideration of how work is structured, allocated, and preserved. In mixed-workforce environments, that consideration is now unavoidably broader, and legally unavoidable.
