About this Document

A Drug and Alcohol Policy is a critical document for any Australian business. It acts as a formal rulebook for how you manage the risks associated with alcohol and drug use at work. For tradespeople and small business owners, this is not just about ticking boxes. It is about protecting your livelihood, your employees, and the public. This guide explains exactly what this document is, why you need it, and how to create one that works for your specific industry. We will look at the legal requirements under the Fair Work Act 2009 and the Work Health and Safety Act 2011. We will also cover the Australian Standards that guide testing procedures. The aim is to give you a clear path to a safer workplace without the legal jargon. In Australia, work health and safety laws place a duty of care on business owners. You must ensure the health and safety of your workers while they are at work. This includes managing risks related to impairment. If a worker is under the influence of drugs or alcohol, they are a hazard. They can hurt themselves, their mates, or members of the public. A Drug and Alcohol Policy is your primary tool to manage this hazard. It sets clear expectations for everyone. It tells workers what is allowed and what is not. It explains what will happen if they break the rules. Without a policy, you leave your business open to significant risk. If an accident happens and you cannot show you took steps to manage impairment, you could face heavy fines or even jail time. The Safe Work Australia codes of practice make it clear that managing fatigue and drug use is a part of your duty. You cannot ignore it. Many employers worry about privacy and discrimination. They are unsure if they can legally test for drugs or alcohol. This is where the policy becomes your shield. If you follow a fair and consistent policy, you are within your rights to require a safe workplace. The Fair Work Ombudsman supports employers who take reasonable management action. Having a written policy proves your actions are reasonable and not discriminatory. This guide covers the key components you must include. We will talk about the scope of the policy. Who does it apply to? Does it cover contractors and visitors? We will discuss the definitions. What do we mean by drugs? What do we mean by alcohol? We will look at the rules for work functions and business travel. It is not just about on site use. It is about being fit for work when you arrive. For tradespeople driving vehicles or operating heavy machinery, this is vital. A zero tolerance approach is common in high risk industries. We will explain what that means. We will also discuss the difference between prescribed medications and illicit drug use. You must support workers with legitimate medical needs while ensuring they are not impaired. The process of testing is a major area of confusion. There are strict standards you must follow. The Australian Standard AS/NZS 4308:2008 sets the rules for urine testing. The AS 4760 standard covers oral fluid testing. Your policy should specify which method you use and why. It must explain the procedures for collection and analysis. If you do not follow these standards, a worker can challenge the result. This can lead to unfair dismissal claims. We will outline the disciplinary procedure. What happens if a worker tests positive? What happens if they refuse a test? Your policy must set out a clear process. It usually involves counselling, rehabilitation, and dismissal as a last resort. This approach is seen as fair by the Fair Work Commission. It shows you are trying to help the worker rather than just punishing them. However, for serious safety breaches, immediate dismissal may be warranted. The policy must be clear on this distinction. Implementing the policy is just as important as writing it. You cannot write it and file it away. You must consult with your workers. Under the WHS Act, you must consult on matters that affect their health and safety. This policy definitely affects them. You need to train them on the content. They must sign an acknowledgement to prove they understand it. Regular reviews are also necessary. Laws change and your business changes. The policy should be a living document. We will also discuss the specific challenges for trades. Working on client sites, driving long distances, and working in isolated areas all present unique risks. Your policy needs to address these scenarios. For example, how do you manage alcohol consumption at the end of the day in a remote camp? What are the rules for having a beer at a client site after hours? These grey areas cause the most problems. A good policy provides black and white answers to these questions. We will touch on the role of Employee Assistance Programs. These are confidential counselling services. They are a great resource for workers struggling with substance abuse. Including EAP details in your policy shows you care about their wellbeing. It is a positive step that can prevent issues before they become incidents. Finally, we will look at the cost of not having a policy. Apart from the legal risks, consider the productivity losses. Consider the damage to your reputation. If your clients see your workers behaving badly or working while impaired, you will lose contracts. In competitive industries like construction and mining, a safety record is a selling point. A Drug and Alcohol Policy is a key part of that record. This guide provides the knowledge you need to build that policy. It is written for you, the Australian business owner. It uses plain English and focuses on practical steps. It references the specific laws that apply to you. By the end of this guide, you will know exactly what to put in your document. You will know how to enforce it fairly. You will know how to keep your business safe and compliant.

Purpose and Scope

Explains why the policy exists and who it covers.

This policy establishes a clear framework to maintain a safe, productive, and legally compliant workplace by preventing hazards related to drugs and alcohol. The primary aim is to eliminate risks to health and safety that could arise from impairment, ensuring every worker remains fit for duty while on site or representing the business. This policy applies universally to all individuals engaged in work activities, including all direct employees, subcontractors, labour hire workers, apprentices, and visitors entering any company-operated site or vehicle. By enforcing these standards, the business meets its obligations under Australian law to provide a working environment that is without risk to health and safety.

In the Australian building and construction industry, working while impaired by drugs or alcohol is a significant safety hazard. As a business owner or tradesperson, you have a legal duty to protect your mates, your clients, and the public. This policy is not just about following rules, it is about ensuring that everyone on site goes home safely. Operating heavy machinery, working at heights, or using power tools requires full concentration and physical coordination. Alcohol and recreational drugs, as well as certain prescription medications, can slow reaction times and impair judgment, leading to serious accidents.

This policy is designed to help you comply with the Work Health and Safety Act 2011 (WHS Act) and the Work Health and Safety Regulations. Under these laws, Persons Conducting a Business or Undertaking (PCBUs) must eliminate or minimise risks to health and safety so far as is reasonably practicable. Failing to manage drug and alcohol risks can result in substantial fines or prosecution by Safe Work or WorkSafe authorities. , this policy aligns with relevant Australian Standards, such as AS/NZS 4308:2008 for the collection and testing of urine, and AS/NZS 4760:2019 for oral fluid testing, ensuring that any testing procedures used on site are accurate and legally defensible.

You must be aware that this policy applies to everyone, regardless of their role or position on the site. It covers the use of illicit drugs, the misuse of alcohol, and the inappropriate use of prescription medication that affects a person's ability to work safely. It is important to understand that safety obligations are shared. While the business provides the policy and education, workers also have a duty under the WHS Act to take reasonable care of their own health and safety and to not adversely affect the health and safety of others. This means you must not arrive at work under the influence and you must notify your supervisor if you are taking medication that may impact your ability to perform your duties safely.

If a worker or contractor breaches this policy, the business will take immediate action to rectify the situation. This may include standing the individual down to prevent an immediate safety risk, requiring a mandatory return to work drug and alcohol test, or disciplinary action up to and including termination of employment or contract. By adhering to these standards, we ensure that our operations remain professional, compliant, and safe for everyone involved.

Rules and Standards

The specific rules regarding alcohol and drugs.

Specific Rules and Standards

Employees, subcontractors, and visitors must follow these rules strictly to ensure a safe workplace. Failure to comply may result in immediate disciplinary action or termination of employment.

Zero Tolerance for Illicit Drugs The use, possession, distribution, or being under the influence of illicit drugs is strictly prohibited while on company premises, in company vehicles, or while working on client sites. This includes a zero tolerance approach to recreational drugs and the misuse of prescription medications. This rule supports our obligations under the Work Health and Safety Act 2011 (Cth) and equivalent state legislation, which requires persons conducting a business or undertaking to eliminate or minimise risks to health and safety.
Alcohol Limits and Consumption We maintain a zero tolerance policy regarding alcohol consumption during work hours. You must not report for duty if your Blood Alcohol Concentration (BAC) is 0.00%. You must not consume alcohol while on duty, during scheduled breaks, or in company vehicles. This applies to all staff, including management and tradespeople working on construction sites regulated by Safe Work Australia codes of practice.
Prescription Medication and Impairment If you take medication that is prescribed by a doctor or purchased over the counter, you must determine if it affects your ability to work safely. You have a legal obligation to disclose any potential side effects, such as drowsiness or reduced coordination, to your supervisor before starting work. It is a safety breach to work while impaired by medication. We will treat this disclosure confidentially and may adjust your duties or require a fitness for work assessment to ensure compliance with the Work Health and Safety Regulations.
Testing and Inspection To comply with industry standards and federal law, we may conduct drug and alcohol testing. This includes random testing, pre-employment testing, and 'for cause' testing if we suspect you are impaired. Refusal to submit to a test is a breach of this policy and will be treated the same as a positive result. Testing procedures follow the Australian Standards (AS/NZS 4308:2008) for urine sample collection and AS 4760 for oral fluid testing to ensure accuracy and legal defensibility.
Searches and Seizures To maintain safety, the company reserves the right to search company property, lockers, vehicles, and personal bags brought onto site if there is reasonable suspicion of prohibited items. Any illicit substances or alcohol found will be confiscated, and the authorities may be notified.
Fit for Work Obligations You must arrive at work and remain fit for duty for your entire shift. If you feel unwell, fatigued, or unable to perform your tasks safely for any reason, you must notify your supervisor immediately. Do not operate machinery, drive vehicles, or perform high-risk work if your judgment is compromised. This individual responsibility is a core requirement of the Model Code of Practice: Managing the risks of drugs and alcohol at work.

Testing Procedures

Details on how and when testing occurs.

Testing Procedures

Testing is a critical part of maintaining a safe workplace. We conduct testing to ensure the safety of all workers and the public. All testing follows strict procedures to ensure accuracy and fairness. We adhere to the Work Health and Safety Act 2011 (WHS Act) and relevant Work Health and Safety Regulations. We also follow the relevant Australian Standards for specimen collection and testing.

Types of Testing

We use three main types of testing.

Pre-employment testing is a condition of employment for all new hires. You must provide a negative sample before starting work.
Random testing occurs without notice. A third-party provider selects employees using a random number generator. This ensures no one is targeted personally. You must proceed to the testing area immediately when selected.
For cause testing happens when a supervisor observes behaviour suggesting impairment. This includes slurred speech, lack of coordination, or smelling of alcohol or cannabis. If a supervisor suspects impairment, you must stop work immediately and undergo a test.

Testing Method

We use oral fluid (saliva) testing as the primary method for detecting drugs. This method is preferred for safety-sensitive industries as it detects recent use. We use urine testing only in specific circumstances, such as confirming a positive result or conducting a medical assessment.

All testing uses devices and procedures that comply with AS/NZS 4760:2019 (Oral fluid collection devices for drugs of abuse testing). This standard sets out the requirements for the equipment and the collection process to ensure reliable results. For urine testing, we comply with AS/NZS 4308:2008 (Procedures for specimen collection and the detection and quantitation of drugs of abuse in urine).

The Collection Process

A trained and accredited collector conducts the test. The process is private and professional. You must provide valid identification, such as a driver's licence or proof of age card. The collector observes the collection to prevent tampering. If the initial screening result is negative, the process ends there.

If the initial result is non-negative (positive), the collector seals the sample. We send it to a National Association of Testing Authorities (NATA) accredited laboratory for confirmation testing. The laboratory analysis determines the exact presence of drugs. You have the right to dispute the result and request a re-test of the split sample at your own expense.

Refusal to Test

Refusing to provide a sample is a serious breach of this policy. Under the WHS Act, failing to comply with a reasonable safety instruction is an offence. If you refuse a test without a valid medical reason, we will assume you have tested positive. This may lead to immediate disciplinary action, including termination of employment.

Prescription Medication

If you take prescription medication, you must disclose this to the collector before the test. You must provide evidence of a valid prescription. While we respect your medical needs, safety comes first. If the collector believes the medication impairs your ability to work safely, you will not be allowed to work until a medical professional clears you.

Required

Disciplinary Action

Consequences for breaching the policy.

Disciplinary Action

Breaching this policy is a serious matter. We are committed to maintaining a safe workplace for everyone. If you do not follow these rules, we will take action. The process depends on how serious the breach is.

We follow the principles of procedural fairness when dealing with any misconduct. You have the right to know the details of the allegation and to provide your side of the story. We will consider your explanation before making a decision.

For minor or first-time breaches, we may issue a formal written warning. This is a record of the incident. It outlines what rule you broke and what you must do to fix it. We might also require you to attend counselling. This helps you understand the risks of alcohol or drug use at work. Counselling supports you to get back on track and meet our safety standards.

However, zero tolerance applies to serious breaches. If you arrive at work under the influence of drugs or alcohol, or if you refuse to take a test when asked, we view this as serious misconduct. In these cases, we will not issue warnings. We may dismiss you instantly.

Summary dismissal is a heavy penalty, but it is necessary to protect the health and safety of the team. We base this decision on your duty of care under the Work Health and Safety Act 2011 (Cth) and corresponding state laws. Being impaired at work puts you and your workmates at risk of injury or death.

If we dismiss you for a serious breach, the dismissal will follow the standards set by the Fair Work Act 2009 (Cth). This ensures the action is not harsh, unjust, or unreasonable. We must follow the Fair Work Commission regulations regarding dismissal.

We treat the use, possession, or distribution of illegal drugs at work as a very serious breach. Supplying drugs to others at work is a criminal offence. We will report this matter to the police immediately. This will lead to instant dismissal and potential legal prosecution.

All disciplinary actions remain confidential. We keep records on your personal file. If you improve your behaviour after a warning, that record does not lead to further action. We want to help you work safely, but we will not compromise on safety.

Support and Rehabilitation

How the company helps workers with dependency issues.

The company is committed to supporting the health, safety, and wellbeing of all workers. We understand that drug and alcohol issues can be complex medical conditions rather than simple disciplinary matters. Our primary goal is to identify problems early and provide access to rehabilitation so workers can return to work safely and sustainably.

We encourage all workers to self-identify if they are struggling with substance use. Early disclosure allows the company to provide support before a workplace incident occurs. If you voluntarily approach management or a supervisor to discuss a drug or alcohol problem, we will treat this as a health issue. We will not use this disclosure as grounds for disciplinary action, provided you agree to engage with a support program and comply with any appropriate safety measures.

Support Services

We provide access to an Employee Assistance Program (EAP). This service offers free, confidential, and professional counselling for you and your immediate family members. The EAP can help with stress, anxiety, depression, and drug or alcohol dependency. Contact details for the EAP are displayed on the site noticeboard and in the company induction handbook. You do not need to tell your supervisor if you contact the EAP directly.

Rehabilitation Process

If a worker discloses an addiction issue, we will work with them to develop a suitable support plan. This may involve approving paid sick leave or unpaid leave to attend medical appointments or a rehabilitation program. We may request a medical certificate or a fitness for work assessment from an independent medical practitioner. This assessment helps us understand any limitations and ensures we do not assign tasks that could put you or your workmates at risk while you recover.

Workplace Safety

Despite our commitment to rehabilitation, safety remains our top priority. This support framework operates under the Work Health and Safety Act 2011 (Cth) and relevant state or territory laws. Under these regulations, the company has a primary duty of care to ensure the workplace is safe. This means we cannot allow a worker to remain on site if they are under the influence of drugs or alcohol or if their condition poses an imminent risk to themselves or others.

A support plan will always balance your privacy with the safety requirements of the job site. If you are participating in a rehabilitation program but fail to comply with the treatment plan or turn up to work unfit for duty, we may need to revisit the support arrangement and follow standard disciplinary procedures.

Privacy

All medical information and personal details disclosed during the support and rehabilitation process will remain strictly confidential. We will only share this information with management or human resources staff who are directly involved in managing your rehabilitation or ensuring site safety. We comply with the Privacy Act 1988 regarding the handling of your personal health information.
