Unlawful Industrial Action: Employer Rights And Responses In Australia

Industrial action can be stressful at the best of times. When your roster is suddenly disrupted, production slows down, or staff stop work altogether, it can feel like your business is being held hostage.

For many small business owners, the most difficult part is uncertainty: Is this lawful? What can we do without making things worse? Are we exposed to penalties or claims?

This is where understanding when industrial action is unlawful matters. If you respond too aggressively, you can trigger unfair dismissal, adverse action, or general protections risks. But if you do nothing, your operations (and customer relationships) can quickly take a hit.

Note: This article is general information for Australian employers and isn’t legal advice. Because the rules can be technical and fact-specific, it’s worth getting advice about your specific circumstances.

Below, we break down what unlawful industrial action is in Australia, how it commonly shows up in small businesses, and practical steps you can take to respond in a legally safer way.

What Is Unlawful Industrial Action?

In Australia, “industrial action” generally refers to action taken by employees (and sometimes employers) in relation to work, usually to support claims about wages, conditions, or workplace issues.

Industrial action can take different forms, including:

• stopping work (a strike)
• bans or limitations on certain duties (for example, refusing to do particular tasks)
• partial work bans (for example, doing some work but refusing other work)
• work-to-rule (performing duties strictly to minimum requirements to slow output)
• overtime bans

Unlawful industrial action is industrial action that is not protected by the legal framework (primarily under the Fair Work Act). In simple terms, it’s industrial action that employees take when they do not have the legal right to take it.

Even if the underlying concern is real (like safety complaints or pay disputes), the action itself can still be unlawful if it doesn’t meet the legal requirements.

“Protected” vs “Unprotected” Industrial Action

Industrial action may be “protected” if it happens during a lawful bargaining process for an enterprise agreement and specific steps have been followed (such as giving proper notice and holding a protected action ballot in many cases).

If those steps aren’t met, the action is typically “unprotected” (which people commonly refer to as unlawful industrial action). This distinction matters because it affects:

• what orders the Fair Work Commission can make
• whether employees are protected from certain consequences
• what options you have as the employer

Common Examples Of Unlawful Industrial Action In Small Businesses

Unlawful industrial action doesn’t always look like a dramatic walkout. For small businesses, it often shows up in more subtle (but still disruptive) ways.

Sudden Stop-Work Meetings Or Walkouts

A group of employees may decide to stop work immediately due to a workplace dispute, without notice, and outside of any protected bargaining period.

If there’s no legal basis and the proper process hasn’t been followed, this can amount to unlawful industrial action.

Overtime Bans Or Refusing Key Tasks

Sometimes staff continue working, but refuse overtime, refuse certain duties, or coordinate a partial ban to pressure you to change conditions.

These are still forms of industrial action. They may be unlawful industrial action if not protected under the Fair Work framework.

Coordinated Absences Or “Sick-Outs”

If a group of staff all call in sick on the same day to apply pressure (without genuine illness), this can create serious operational issues and may raise misconduct concerns.

Be cautious, though: sickness and personal leave rights are protected, and employers should avoid assumptions. If you’re managing repeated absences, it can be important to handle medical evidence requests properly and consistently.

Refusing To Work Due To Safety Concerns (Without A Clear Basis)

Work health and safety is a legitimate issue, and employees may have rights to cease unsafe work in certain circumstances.

But if employees refuse to work without a reasonable safety basis (or don’t follow the relevant WHS processes), you may be dealing with unlawful industrial action or misconduct rather than a lawful safety refusal.

Why Unlawful Industrial Action Creates Legal Risk For Employers

When you’re facing unlawful industrial action, it’s tempting to go straight to disciplinary action or termination. Sometimes that may be an option, but it’s rarely the best “first move” without a plan.

Here’s why the situation can be legally high-risk for employers.

Employment Law Claims Can Escalate Quickly

If you issue threats, reduce hours, or discipline staff without following a fair process, you could trigger disputes such as:

• unfair dismissal claims (if someone is terminated)
• general protections / adverse action claims (if the employee alleges the action was because of workplace rights, industrial activity, or complaints)
• discrimination issues (if responses disproportionately affect certain employees)

Having clear documents and processes matters. For example, a well-drafted Employment Contract can help clarify duties, expectations, and disciplinary processes, but it still needs to be applied fairly.

You Still Need To Keep The Business Running

Small businesses often don’t have spare capacity. If a handful of staff take industrial action, it can stop the business from delivering services, meeting deadlines, or opening at all.

That operational pressure can lead to rushed decisions. Unfortunately, rushed decisions are where legal risk often increases.

Reputational And Customer Impact

Disruptions often spill into customer-facing channels. Clients may ask why deliveries are late or why service levels dropped.

In some industries, ongoing disruptions can also trigger contract breaches with customers or suppliers, which creates another layer of risk (and cost).

How To Respond To Unlawful Industrial Action (A Practical Step-By-Step Approach)

If you suspect you’re dealing with unlawful industrial action, you’ll usually get better results by responding calmly, documenting everything, and acting strategically.

Here’s a practical approach we often recommend employers consider.

1. Identify What’s Actually Happening (And Why)

Start by clarifying what the conduct is:

• Are employees stopping work completely, or partially?
• Is it coordinated?
• What are employees saying is the reason?
• Is there an enterprise bargaining process underway?
• Is there a genuine safety issue being raised?

It’s also worth checking whether there’s any misunderstanding about rostering, notice, or role expectations. In small businesses, disputes can sometimes begin as miscommunication and then escalate.

2. Document Events In Real Time

Write down dates, times, who was involved, what was said, and what work was impacted.

Keep copies of:

• rosters and timesheets
• messages/emails to and from employees
• customer cancellations or operational impacts
• any incident reports or safety complaints

This documentation becomes important if you need to seek an order to stop the action, defend a claim later, or take disciplinary steps.

3. Communicate Clearly (Without Threatening Or Escalating)

Often, your first written communication sets the tone. In many cases, you’ll want to:

• acknowledge the issue (without conceding wrongdoing)
• ask employees to return to work and explain expectations
• invite employees to raise concerns through a structured process
• confirm you’ll investigate concerns promptly

Avoid heated language. Avoid “blanket” accusations. And be careful not to imply punishment for raising concerns, as this can increase general protections risk.

4. Consider Whether You Can Stand Employees Down (But Do It Carefully)

Employers sometimes ask whether they can stand down employees when operations are significantly disrupted.

This can be legally complex and fact-dependent. Under the Fair Work Act, a stand down without pay is only available in limited circumstances (for example, where there is a stoppage of work the employer cannot reasonably be held responsible for, and the employee can’t usefully be employed), and it can also be affected by any applicable enterprise agreement, award or contract terms.

Industrial action-related disruption doesn’t automatically mean you can stand employees down, and the safer pathway may depend on whether employees are actually refusing to perform work, whether there is any work they can usefully do, and what industrial instrument applies.

If you’re considering a stand down while investigating misconduct or disruptions, it’s worth getting advice early. The line between a lawful stand down and an unlawful/unreasonable direction can be thin. (This is also why strong policies and processes matter when you’re standing down an employee pending investigation.)

5. Manage Pay Carefully During Industrial Action

Pay issues are one of the fastest ways to escalate a dispute.

Depending on the type of industrial action, employees may not be entitled to payment for time they don’t work. Partial work bans are particularly technical: there are specific rules about when you can withhold pay, when you can make a proportionate deduction, and when you need to give written notice.

However, withholding pay incorrectly can backfire and create wage compliance risk. If you’re unsure, pause and get advice before making payroll decisions that could create underpayment claims.

6. Use A Fair Process If You Move Toward Discipline

If the conduct is serious and continues, you may consider disciplinary steps.

Even if the action is unlawful industrial action, it’s still important to follow a fair and procedurally sound process, which typically includes:

• clearly outlining the allegations
• giving the employee a chance to respond
• considering their response genuinely
• documenting the decision-making
• applying consequences consistently

A structured warning process can reduce risk. If you do issue formal warnings, make sure they’re accurate, specific, and tied to expectations.

7. Seek Help Early If It’s Spreading Or Affecting Operations

Once unlawful industrial action becomes entrenched, it’s harder (and more expensive) to resolve.

Early advice can help you:

• confirm whether action is likely unprotected
• choose the right communication strategy
• avoid missteps that trigger general protections exposure
• prepare for any formal steps (like Fair Work Commission processes, including potential “stop” orders)

How To Reduce The Chance Of Unlawful Industrial Action In The First Place

You can’t eliminate workplace conflict entirely, but you can reduce the chance it turns into unlawful industrial action by putting strong foundations in place.

Set Clear Expectations With Proper Employment Documentation

Many disputes come down to misunderstandings about duties, hours, flexibility, or pay.

Clear contracts help. If you engage employees without clear written terms, you may have less leverage when disputes arise (and more room for disagreement over what was actually agreed).

For businesses that use casual or flexible staff, it can also help to have a clear shift management process and expectations around cancellation and changes (including a compliant shift cancellation policy where relevant).

Keep Workplace Policies Practical (Not Overly Complicated)

Policies can help you manage issues consistently, particularly around:

• workplace conduct and behaviour
• complaints handling and escalation
• leave and evidence requirements
• use of company property and systems

The key is that policies must be used in practice. A policy that exists but isn’t followed can be a problem if a dispute ends up in front of a regulator or tribunal.

Address Complaints Before They Become “Collective Action”

Small issues can become large issues if employees feel ignored.

If staff raise concerns (about safety, harassment, wages, or bullying), take them seriously and deal with them promptly. Even if you disagree with the complaint, a respectful process can reduce the chance staff “take matters into their own hands” through unlawful industrial action.

Use Accurate Notices And Letters When You Need To Escalate

If a dispute is escalating, a well-written letter can help de-escalate and set a clear path forward.

For example, if there is alleged misconduct, a show cause letter may be appropriate in some situations, because it clearly sets out the concerns and invites a response before a final decision is made.

Key Takeaways

• Unlawful industrial action generally refers to industrial action that isn’t “protected” under the Fair Work framework, even if employees believe they have a legitimate grievance.
• Unlawful industrial action can include strikes, partial work bans, refusal of certain duties, overtime bans, and coordinated disruptions.
• Your response needs to be strategic: document what’s happening, communicate clearly, and avoid rushed decisions that can trigger unfair dismissal or general protections exposure.
• Pay decisions during industrial action can be legally risky if mishandled, so it’s important to approach payroll carefully and get advice where needed (especially for partial work bans).
• Prevention is often easier than cure: clear workplace documents, practical policies, and early complaint handling reduce the chance disputes escalate into industrial action.
