General protections claims are skyrocketing in Australia. The Fair Work Commission recorded a 24% surge in caseload in 2026 — and employers are increasingly on the receiving end. A general protections claim alleges that an employer took “adverse action” against an employee for exercising a protected workplace right or for a prohibited reason (like union activity, pregnancy, age, or raising safety concerns).

The risk is real: the Fair Work Commission can order reinstatement, compensation of up to the maximum annual salary ($95,050 as of 1 July 2026), or damages. But here’s what most employers don’t understand — the burden of proof is on the EMPLOYEE to prove the adverse action. Your job as an employer is to document your business reasons, prove your decision was genuinely unrelated to any protected right, and respond strategically to claims.

This guide walks you through what adverse action really is, how the FWC evaluates claims, the evidence you need, and practical strategies to defend your decisions.

What Is Adverse Action?

Adverse action is unlawful action taken by an employer against an employee that causes, or is likely to cause, detriment. “Detriment” includes dismissal, discipline, demotion, reduced hours, excluding someone from a benefit, or creating a hostile workplace.

The Fair Work Act 2009 (Cth) defines adverse action in section 342. It’s unlawful if taken for a prohibited reason — or if it’s taken in response to an employee raising a workplace right claim.

Common triggers:

• Dismissal following a safety complaint
• Demotion after union involvement
• Reduced hours after requesting flexible work
• Exclusion from training after raising a wage theft concern
• Negative references post-dispute
• Reassignment to undesirable duties after raising discrimination concerns

The key question: was there adverse action (a detriment), and was a prohibited reason the reason or a substantial reason for that detriment? The answer determines whether you face liability.

19 Prohibited Reasons (and the Most Common)

The Fair Work Act lists 19 prohibited reasons. Here are the most common and most likely to trigger claims:

• Union membership or activity — joining, participating in, or requesting representation from a union.
• Seeking conditions via agreement — negotiating enterprise agreements or individual flexibility arrangements.
• Workplace rights — raising concerns about pay, hours, safety, discrimination, or leave entitlements.
• National employment standard — requesting parental leave, flexible work, jury service, or compassionate leave.
• Discrimination grounds — age, race, gender, disability, pregnancy, religion, political opinion, sexual preference.
• Workplace health and safety — raising safety concerns or participating in safety disputes.
• Whistleblower disclosures — reporting unlawful conduct, workplace misconduct, or safety breaches to authorities or internally.
• Jury service — performing jury duty or temporary absence from work.
• Temporary absence — military service, blood donation, emergency services volunteering.

Critical point: Even mentioning a prohibited reason as a factor can create liability if the FWC finds it was “a substantial reason” for your action. For example, if you dismiss someone partly for performance but also because they raised a safety concern, the FWC may find you liable.

The Burden of Proof: Your Key Advantage

Here’s the critical legal point that changes everything: the employee must prove (on balance of probabilities) that there WAS adverse action AND that a prohibited reason was THE reason or A substantial reason for it.

You do not have to prove your actions were lawful. You have to show your genuine business reason. This is a significant legal advantage.

The Fair Work Commission will consider multiple factors when assessing a claim:

• Temporal relationship — how close in time was the adverse action to the protected conduct? Suspiciously rapid action is a red flag.
• Your conduct before and after — did you treat this employee differently than others in similar circumstances?
• Your documented reasons — were they genuine and supported by contemporaneous evidence?
• The broader context — what else was happening at the time in your workplace?
• Knowledge of decision-maker — did the person who made the decision know about the protected conduct?

If the employee raises a prohibited reason but you can show a genuine, separate business reason (backed by solid documentation), the claim often fails.

The Employer’s Three-Pillar Defence Strategy

Your defence rests on three pillars. The stronger your documentation, the more pillars you can defend:

Pillar 1: No Adverse Action Occurred
Argue that your action was not adverse action — that it did not cause detriment or was part of normal business practice. For example, directing someone to follow a policy is management; it’s not detriment unless it causes measurable harm.

Pillar 2: No Prohibited Reason Was Involved
Show that your reason for the action was unrelated to any prohibited reason. You must prove: (a) the decision-maker was unaware of the protected conduct, (b) the decision was based on documented performance, conduct, or safety grounds, and (c) you’d treat anyone else the same way in the same situation.

Pillar 3: Genuine Business Reason (Even If Prohibited Reason Was Known)
Even if a prohibited reason existed and the decision-maker knew about it, it wasn’t the reason for your action. Present: performance records (with dates BEFORE the protected conduct), consistent treatment of other employees, safety or operational documentation, and expert evidence on why the decision was necessary.

Documentation That Defends You

When adverse action claims arise, your documentation becomes your evidence. You must maintain:

• Performance and conduct records: Email correspondence about performance issues (with dates), written warnings, improvement plans, counseling notes, performance reviews, attendance records, productivity metrics, safety incident reports.
• Decision-making documentation: A memo outlining the decision and reasons (dated BEFORE any announcement to the employee), minutes from disciplinary or performance meetings, evidence that the decision-maker didn’t know about the protected conduct, and a comparison showing how you handled similar conduct by other employees.
• Consistency evidence: Similar disciplinary outcomes for similar conduct by other employees, training records showing policies were communicated uniformly, prior decisions in analogous situations.
• Timing evidence: Any documentation showing the decision was being considered BEFORE the protected conduct occurred.

Keep all records for at least 3 years after the employment relationship ends. When a claim arrives, this documentation becomes your shield.

The 21-Day Application Window

Employees have a strict 21-day deadline from the date of adverse action to lodge a claim with the Fair Work Commission. This is a hard cutoff — claims filed after 21 days are out of time (though the FWC can extend in rare exceptional circumstances).

Once a claim is lodged, the FWC will serve it on you. You’ll have 14 days to respond. Gather your evidence immediately and consult a lawyer before submitting your response.

The FWC Process (2026 Reforms)

The Fair Work Commission overhauled its case management in 2026 to reduce the 24% caseload surge. The new process:

1. Initial assessment — FWC checks if the claim is on time and has standing.
2. Mandatory conciliation — The Commission attempts to resolve the dispute without a full hearing (new requirement).
3. Exchange of agreed facts and settlement — Parties exchange evidence and may settle confidentially.
4. Hearing or “on papers” decision — If unresolved, an FWC member conducts a hearing (or may decide the case based on written submissions if both parties agree).
5. Judgment and orders — The FWC issues a decision and any remedial orders.

If the employee wins, the FWC can order: reinstatement to the same or equivalent role (you can argue it’s not appropriate), compensation for lost earnings and other economic loss, compensation for non-economic loss (hurt, humiliation, damage to reputation), or punitive damages if the conduct was particularly unreasonable. The total compensation cap is $95,050 as of 1 July 2026 (indexed annually).

Common Pitfalls That Lose Claims

Employers lose general protections claims because of:

• No contemporaneous documentation — decisions made “on the fly” with no paper trail to support them.
• Inconsistent treatment — disciplining one employee harshly while ignoring similar conduct by others.
• Temporal proximity — adverse action taken suspiciously soon after protected conduct, suggesting retaliation.
• Contradictory statements — telling the employee one reason, then claiming another in the FWC response.
• Lack of procedural fairness — dismissing without investigation, warnings, or a chance for the employee to respond.
• Admitted knowledge — the decision-maker admits they knew about the protected conduct.
• Reactive emails — angry or defensive emails sent AFTER the protected conduct that suggest retaliation.

Settlement & Confidentiality

Many general protections claims settle before a full hearing. Settlements can include:

• Agreed compensation — commonly $10,000–$60,000 depending on claim strength and potential exposure.
• Confidentiality clauses — both parties sign a non-disclosure agreement and keep the settlement secret.
• Mutual release — both parties give up all related claims against each other.

Confidentiality is attractive to employers — a published FWC decision is public record and can damage your reputation and brand. A confidential settlement, though costly, often avoids the reputational and legal risk of a full hearing. Always obtain legal advice before settling.

Your Action Plan: Defend Now, Avoid Claims Later

Right now:

• Audit your HR policies — are they compliant with the Fair Work Act and your industry standards?
• Review dismissals and discipline from the past 2 years — do you have solid documentation?
• Train your managers on prohibited reasons, adverse action, and procedural fairness.
• Set policy: any discipline or dismissal must be documented with clear business reasons BEFORE action is taken.

When a dispute arises:

• Stop communication with the employee (unless procedurally required).
• Gather all documentation immediately — emails, meeting notes, performance records.
• Notify your employer indemnity insurance provider.
• Consult a lawyer immediately — don’t respond to the FWC without legal advice.
• Prepare a detailed response showing your business reason and how you’ve treated others consistently.

If you’re taken to the FWC:

• Remember: the burden is on the employee to prove adverse action AND prohibited reason.
• Present your contemporaneous documentation showing a genuine business reason.
• Show consistent treatment of other employees in similar circumstances.
• Consider settlement vs. litigation based on your insurer’s advice and the strength of your documentation.
