How strikes and industrial action work in Australia

When staff say they are planning to stop work, the immediate reaction is usually stress. For a small or medium business, even a half-day stoppage can disrupt customers, deadlines and cash flow. But strikes are not something that simply happens to you. In Australia they sit inside a carefully designed legal scheme, and knowing how that scheme operates, rather than reacting to the drama of the moment, is what protects your business.

The scheme is built around a single idea: industrial action is legal only as a bargaining lever, not as a general right to protest. Employees can stop work, impose bans or slow their output, but only while they are genuinely negotiating a new enterprise agreement, and only after a formal ballot and written notice. Get inside that framework and both sides have clear rules, including what happens to pay and who can be stood down. Step outside it and the action becomes unprotected, with a different and riskier set of consequences. This guide walks through the machinery: what counts as industrial action, the ballot and notice steps that make it protected, what that status means for pay, and the traps employers commonly hit.

What counts as industrial action

Australian law defines industrial action more broadly than a full walkout. Section 19 of the Fair Work Act 2009 (Cth) captures four kinds of conduct:

• Stoppages: a failure or refusal by employees to attend for work, or to perform any work at all while at work.
• Bans and restrictions: a ban, limitation or restriction on the performance of work, such as refusing overtime or refusing a particular task.
• Work slowdowns: performing work in a way that is different from usual and that restricts, limits or delays output, or adopting a practice with that result.
• Lockouts: the employer preventing employees from performing work under their contracts without terminating them.

Two things are explicitly not industrial action. First, action the employer has authorised or agreed to. Second, a refusal to work based on a reasonable concern about an imminent risk to health or safety, where the employee did not unreasonably refuse safe alternative work the employer offered. That carve-out matters: a genuine safety refusal is not a strike, and treating it as one is a legal mistake of its own.

Who is involved when a stoppage looms

The scheme brings together a small cast of players, each with defined roles:

• Employees and their bargaining representative: usually a union, but employees can bargain for themselves. Only a bargaining representative can drive the steps that make action protected.
• The employer: the target of the action, and the party with obligations around pay, stand down and bargaining conduct.
• The Fair Work Commission (FWC): the independent tribunal that runs the ballot approval process, and later the body that can order unprotected action to stop or suspend protected action in defined circumstances.
• The ballot agent: an independent body, in practice the Australian Electoral Commission, that conducts the protected action ballot.

The competing tension is easy to see. Employees and unions want leverage to push claims; you want business continuity and predictable costs. The scheme exists to force both sides to negotiate seriously before anyone takes action, and to keep the action itself lawful, time-limited and paid for by nobody.

The gate: protected action only happens inside enterprise bargaining

The single most important rule is that protected industrial action exists only for one purpose: supporting or advancing claims for a proposed enterprise agreement. There is no protected action outside bargaining. A protest about a pay cut imposed unilaterally, a dispute about a dismissal, or a campaign about conditions that have nothing to do with a new agreement does not qualify.

Even within bargaining, several filters apply before action can be protected:

• The claims must be about permitted matters: Action in support of a claim to include unlawful terms, such as terms that would breach other laws, is not protected.
• The bargaining representative must genuinely be trying to reach agreement: This is a statutory requirement, not a formality. A representative who refuses to meet, respond to proposals or consider alternatives cannot keep the protection.
• No pattern bargaining: Action cannot be part of a coordinated strategy of pushing identical terms across multiple employers.
• The agreement's nominal expiry date must have passed: Section 417 of the Act prohibits industrial action from the day an enterprise agreement is approved until its nominal expiry date passes, and the Federal Court can grant injunctions against a contravention. In practice this means employees covered by an in-term agreement cannot lawfully take protected action at all, no matter how unhappy they are.

Step one: the protected action ballot

Before any protected action can happen, employees must vote for it in a formal ballot. A bargaining representative applies to the FWC for a protected action ballot order under section 437. The application must specify the groups of employees to be balloted and the questions to be put, including the nature of the proposed action.

The FWC must make the order if it is satisfied the applicant has been, and is, genuinely trying to reach an agreement (section 443). The ballot is then run by an independent agent, in practice the Australian Electoral Commission.

The results only authorise action if the thresholds in section 459 are met:

• at least 50% of the employees on the roll of voters actually voted; and
• more than 50% of the valid votes approved the action.

Timing is strict. The action must commence within 30 days of the declaration of the ballot results, unless the FWC extends that period once by up to 30 days. A ballot that passes but is never acted on expires, and any later action would need a fresh ballot.

Step two: written notice before the action starts

Protected status also requires written notice under section 414. The bargaining representative must give the employer written notice before anyone engages in employee claim action:

• at least 3 working days before the action starts, for a single-enterprise agreement; or
• at least 120 hours before, for a multi-enterprise agreement; or
• a longer period of up to 7 working days if the ballot order specifies one.

The notice cannot be given until the ballot results have been declared, and it must specify the nature of the action and the day it will start. An employer who wants to respond with a lockout must give equivalent notice to each bargaining representative and take reasonable steps to notify affected employees.

Notice matters for a practical reason beyond legality: it converts a surprise into a managed event. The 3 working days are your window to plan rosters, brief supervisors and decide how you will handle pay, all before the first day of action.

What protected status means for pay

This is where the scheme bites hardest, and where employers most often err. Section 470 does not merely let you withhold pay during protected industrial action. It prohibits you from making a payment to an employee in relation to the total duration of the action on a day the employee engaged in it. Paying anyway is a contravention of a civil remedy provision in its own right, separate from any underpayment dispute.

Partial work bans are treated differently under section 471. If an employee performs some work but bans other duties, you may reduce pay proportionally, but only after giving the employee written notice stating the proportion. Alternatively, you can give written notice that you will not pay at all and refuse to accept partial performance until the employee is prepared to perform all of their normal duties. If you give no notice, you must not reduce the employee's pay because of the ban. The process, not the principle, is what protects you.

There is a special rule for overtime bans. The no-payment rule only applies to overtime the employer requested or required, which the employee refused in breach of their obligations under a modern award, enterprise agreement or contract. An overtime ban that does not breach those obligations is not caught by the payment rules at all.

Standing employees down during a stoppage

If protected industrial action means your employees cannot usefully be employed, section 524 allows you to stand them down for the period, with no obligation to pay them for it. Three conditions apply:

• the industrial action must not be action organised or engaged in by you. You cannot stand employees down because of your own lockout;
• the employee must genuinely be unable to be usefully employed, which is a factual question about whether there is productive work available; and
• the stand down must be for the period of the circumstance only.

Employees cannot be stood down while on authorised leave or other authorised absence (section 525). And if an enterprise agreement or contract of employment already contains stand-down terms for the circumstance, those terms govern, and they may add consultation or notice requirements you must satisfy first.

Stand down is a response to the stoppage, not a punishment. An employee stood down because there is genuinely no useful work is not being disciplined, and the distinction matters for what you can and cannot say and do around it.

The flip side: employees are shielded from retaliation

The scheme protects employees who do things lawfully. Section 340 prohibits adverse action against an employee because of a workplace right, and section 346 prohibits it because an employee engages in industrial activity. Taking part in industrial action is expressly defined as engaging in industrial activity (section 347).

Adverse action includes dismissal, injuring the employee in their employment, altering their position to their prejudice, or discriminating between employees. Threatening any of these because an employee voted in a ballot, or participated in protected action, exposes you to a general protections claim with a reversed onus: you would need to prove your reason was not a prohibited one.

This does not mean protected action is a free pass. Misconduct that is separate from the action itself, such as harassment, violence, property damage or serious safety breaches, can still be managed through your normal disciplinary process. The line is between responding to the action, which the scheme regulates, and punishing the person for taking it, which it forbids.

When action is unprotected

Action that skips any of the steps above is unprotected, and the consequences are different. The FWC must make an order that unprotected industrial action stop, not occur or not be organised, whether it is happening, threatened or being organised (section 418). A spontaneous walkout without a ballot, action during the term of an agreement, or a stoppage unconnected to bargaining can all be shut down within days by order, and continued defiance can attract penalties.

Unprotected action also strips employees of the scheme's protections. They are still not entitled to be paid for time they did not work, and unlike protected action there is no ballot regime to hide behind. You can respond through your ordinary employment tools, including lawful disciplinary processes, provided your response is proportionate and is genuinely about the conduct.

The protection against adverse action does not simply switch off, though. Taking part in industrial action, protected or not, is engaging in industrial activity, so dismissing an employee purely for joining a wildcat strike is still a general protections risk. The safer framing is to respond to the action itself: enforce the no-pay position, seek orders to stop the action, and manage any separate misconduct on its own merits.

Where businesses trip up

The scheme's precision is where businesses get caught. The recurring errors are:

• Paying for protected action: Because section 470 makes payment a contravention, the instinct to "keep the peace" by paying staff for a half-day stoppage is itself unlawful.
• Reducing pay for a protected partial ban without notice: Section 471 forbids the reduction unless you have given the written notice first, whatever the employee might have said informally.
• Standing down employees who could usefully work: If there is productive work available, a stand down is not available, and treating it as available while standing people down invites a claim.
• Confusing a safety refusal with a strike: Genuine refusals based on imminent risk are excluded from the definition of industrial action entirely.
• Letting a ballot expire: Action that starts after the 30-day window, or the extended period, is not authorised by the ballot and becomes unprotected.
• Forgetting that protected action can be suspended: The FWC must suspend or terminate protected action that threatens life, personal safety, health or welfare, or significant damage to the economy (section 424), and applications are decided urgently, within 5 days.

When a lawyer earns their fee

The moments where advice pays for itself are easy to name. When a notice of protected action arrives, a lawyer can verify the ballot and notice are actually compliant, because action that fails the paperwork is unprotected and your response options widen. When deciding pay treatment, a lawyer can confirm whether a partial ban triggers the section 471 notice regime, and draft the notices so the deduction survives scrutiny. When action is unprotected, a lawyer can move quickly for FWC orders or court injunctions under section 417 or 418, and can keep your disciplinary response within the adverse action rules. And if you are heading into bargaining at all, early advice on the good faith requirements keeps you from handing the other side a reason to ballot at all.

The first decisions of a stoppage carry the most risk

If there is one thing to hold onto, it is that a lawful stoppage is not the danger to your business. The danger is in the first round of decisions you make in response: what you pay, whom you stand down, and what you say to the people involved. Each of those is regulated by a precise statutory rule, and each, done wrongly, converts a controlled industrial event into a general protections claim, a contravention, or a stand down dispute that costs far more than the stoppage itself. The scheme hands you a lawful path through all three. Following it, with advice where the paperwork is unfamiliar, is what keeps a difficult fortnight from becoming a costly one.
