General Protections Claims: Shifting Burden of Proof & Employer Defence Strategy 2026

General protections claims are skyrocketing. Fair Work Commission filings jumped 57% in 2025–26, and the trend shows no signs of slowing. Most claims allege prohibited reasons for dismissal, but here’s the critical part for employers: you must prove your action was NOT taken for a prohibited reason.

This is not the same burden as unfair dismissal. It’s not about procedural fairness or reasonableness. It’s about the motive behind your decision — and the FWC assumes the worst unless you prove otherwise.

If your business is scaling, managing terminations, or dealing with workplace disputes, understanding this legal framework is essential. A single miscalculated defence can cost you $19,800 per breach (individual) or $99,000 per breach (organisational). One dismissal, multiple alleged breaches, and you’re looking at six-figure liability.

This guide explains how the burden of proof actually works, what prohibited reasons the FWC protects, and the specific defence strategy that keeps employers on the right side of the law.

What Are Prohibited Reasons Under General Protections?

Section 340 of the Fair Work Act 2009 protects employees from suffering “adverse action” for a prohibited reason. Adverse action includes dismissal, but also demotion, pay cuts, adverse changes to working conditions, or any action causing detriment.

Prohibited reasons currently include:

• Union membership or non-membership — engaging in union activity, or refusing to join
• Participation in legal proceedings — giving evidence, making complaints, or initiating claims
• Exercising workplace rights — requesting flexible work, accessing leave, or claiming minimum entitlements
• Jury duty or emergency service — being called to jury duty or emergency service
• Temporary absence from work — absence for jury duty, emergency service, or compassionate grounds
• Whistleblowing — disclosing workplace misconduct or breaches of law (covered under Part 3-1AAA)
• Adverse action for claims under the National Minimum Wage laws — resisting non-compliance with minimum wage schedules

The list is expanding. Recent amendments have added protected attributes and extended whistleblower protections. If you’re managing a termination, assume any of these reasons could be alleged — and prepare your defence accordingly.

The Critical Shift: Burden of Proof in General Protections Claims

Here’s where general protections differ fundamentally from unfair dismissal:

This reversal is crucial. The FWC doesn’t start neutral. Once an employee raises a prohibited reason allegation, you must prove it didn’t happen. You can’t simply argue “there’s no evidence of union bias” — you must affirmatively demonstrate the real reason was legitimate business grounds.

The legal test is a three-step process, established in Prince v Sutton Superannuation Pty Ltd (2015) and consistently applied:

1. Operative reason: What was the operative (actual, real) reason for the action? Employer must prove this with concrete evidence.
2. Causal connection: Does that operative reason have any connection to the prohibited reason? If yes, the claim succeeds.
3. Hypothetical test: Even if the operative reason is legitimate, would the action have been taken if the protected attribute was absent? If the employer cannot prove it would have, the claim succeeds.

This three-step framework has resulted in unfavourable outcomes for employers who relied on vague justifications, selective documentation, or conflicting management accounts.

Proving the Operative Reason: Evidence That Works

To defend a general protections claim, you must prove the operative reason with concrete, contemporaneous evidence. The FWC is suspicious of post-hoc justifications — reasons dreamed up after the action was taken.

Evidence that strengthens your defence:

• Documented performance issues — written warnings, performance review records, email documentation of misconduct before the action
• Consistent application of policy — showing other employees faced the same action for the same breach (e.g., “three other staff were dismissed for unauthorised absenteeism in the past 24 months”)
• Contemporaneous management notes — dated, detailed records of the reason for action recorded at the time (not months later)
• Business records proving capability or behaviour issues — emails, incident reports, client complaints, timesheet records showing objective breaches
• Witness statements from multiple managers — if the decision involved multiple people, consistent accounts strengthen your case
• Absence of contradictory statements — don’t say “we valued her performance” in a reference, then claim poor performance as the dismissal reason

Evidence that weakens your defence:

• Dismissing an employee shortly after they filed a complaint or requested leave
• Citing a reason that doesn’t match contemporary documentation (e.g., claiming “poor performance” but no performance reviews exist)
• Applying the consequence inconsistently (e.g., firing one person for absenteeism, but another employee with worse attendance was retained)
• A manager’s vague testimony: “I just felt she wasn’t right for the role”
• Discovering the real reason during cross-examination (e.g., “Actually, she organised a union meeting, which upset the director”)

The FWC will examine the entire context of the dismissal. If the timing, the language, or the consistency of application suggests a prohibited reason, you’ve lost.

The Hypothetical Test: Would You Have Done It Anyway?

Even if you prove a legitimate operative reason (e.g., poor attendance), the FWC applies the hypothetical test: would you have dismissed this employee if they had NOT taken the alleged protected action?

Example: An employee requests flexible work (a protected workplace right). Two weeks later, you dismiss them for poor performance. You have documented performance issues — excellent. But if the FWC finds that you would NOT have dismissed this particular employee for those performance issues had they not requested flexible work, the claim succeeds.

This is where testimony becomes crucial. The FWC will ask:

• “How many other employees have been dismissed for this level of performance?” (If none, the test fails.)
• “Was this particular performance issue so serious you would normally dismiss, or was it marginal?” (If marginal, hypothetical test fails.)
• “Did the request for flexible work come up in any conversation about dismissal?” (If yes, fails.)
• “Were there opportunities to remediate, and did you offer them to other staff with similar issues?” (If not offered to this employee, fails.)

Courts have found against employers where the operative reason was technically legitimate but the hypothetical test revealed discrimination — the protected action was the real catalyst.

Defending Against Specific Prohibited Reasons

Union Activity or Membership

If an employee alleges you dismissed them for union membership or activity, you must prove the dismissal had nothing to do with the union. Avoid:

• Discussing the union negatively with staff
• Treating unionised employees differently (e.g., stricter performance standards, tighter supervision)
• Making decisions that coincide suspiciously with union announcements

Defence strategy: Maintain objective, documented reasons for all terminations. Don’t let personal frustration about unionisation influence management decisions. The moment a union is involved, every decision becomes exposed to greater scrutiny.

Participation in Legal Proceedings

If an employee gave evidence in an unfair dismissal claim, or filed a complaint with the FWC, and you then dismiss or demote them, the FWC will assume retaliation unless you prove otherwise. This is one of the highest-risk scenarios.

Defence strategy: Avoid any action against an employee within 12 months of legal proceedings involving them. If action is genuinely necessary, document the reason meticulously and show it’s consistent with your treatment of other staff.

Workplace Rights Requests

Requests for flexible work, personal leave, or adjustment under disability discrimination laws are protected. If an employee requests flexible work and you refuse, they must have legitimate business grounds for the refusal — and those grounds must be documented before the request, not invented afterwards.

Defence strategy: Have a written flexible work policy. Document the business case for any refusal in writing. Show you’ve considered the request fairly and offered alternatives if possible.

What Happens if You Lose a General Protections Claim?

Remedies in general protections claims are broader than unfair dismissal. The FWC can order:

• Reinstatement — the employee returns to their role (or a comparable one)
• Compensation — for lost wages, superannuation, and other monetary loss, without a cap (unlike unfair dismissal, which caps compensation at roughly $20,000)
• Injury compensation — damages for humiliation, hurt, or distress caused by the unlawful action
• Penalty — an administrative penalty imposed on the employer by the FWC (up to $19,800 for individuals, $99,000 for organisations)

A single general protections claim can exceed $50,000+ in total liability. If multiple breaches are found (e.g., dismissal PLUS failure to allow participation in legal proceedings), penalties stack.

Practical Defence Checklist for Employers

Before any termination, action, or adverse change:

• ☐ Document the real reason thoroughly and contemporaneously
• ☐ Check if the employee has recently exercised a workplace right, complained, or participated in legal proceedings
• ☐ If yes, pause and ensure the action is necessary and documented to be independent of that exercise
• ☐ Review how you’ve treated other employees in similar situations — is the consequence consistent?
• ☐ Have senior management confirm the decision is independent of the protected reason
• ☐ Draft a clear, written explanation of the operative reason for the action
• ☐ Keep records of any warnings, feedback, or performance issues before the action
• ☐ Ensure the action is not taken within 3–6 months of the protected activity (create temporal distance if possible)

During a claim or FWC conciliation:

• ☐ Provide all contemporaneous documents (don’t wait to be asked)
• ☐ Brief your witnesses consistently — they must tell the same story
• ☐ Be honest about any conflicting statements or missing documentation
• ☐ Don’t over-dramatise the operative reason — the FWC prefers modesty to exaggeration
• ☐ Have your employment law adviser present at conciliation (don’t rely on HR alone)

When to Seek Legal Advice

General protections claims are high-stakes. Seek employment law advice immediately if:

• An employee has recently requested flexible work, leave, or accommodations
• An employee has filed a complaint or participated in legal proceedings
• You’re considering dismissing an employee who has been involved in union activity
• You’ve received a FWC application alleging general protections breaches
• Multiple employees allege the same issue (potential systemic breach)
