One of the most common questions Integrity Sampling receives is about the legalities of drug and alcohol testing. Typically, it’s from a business owner or manager, wondering if their workplace can legally implement drug and alcohol testing.

The answer? Yes, but it’s important to note that this is a qualified yes. Many workplaces can legally implement drug and alcohol testing, however, there are a few questions to answer first and things that need to be in place. So, in this article, we’ll take a deep dive into relevant laws and considerations you should know about before you implement testing.

Yes, you can implement workplace drug and alcohol testing, but…

What is the qualification mentioned above? It’s simply that you need to be able say that the workplace drug and alcohol testing is justified and appropriate due to safety. So, if you want to test your truck drivers, train drivers, pilots, mining people, manufacturing workers and others with safety-focussed roles, you have every reason to go ahead.

However, before you do, there are some other things to consider:

  • While there are no explicit Australian workplace drug testing laws prescribing the mandatory implementation of testing, every workplace is bound by legal obligations outlined in Occupational Health and Safety (OHS) laws, in addition to new industrial manslaughter legislation. These obligations are designed to safeguard the health and safety of both employees and other individuals within the workplace. Implementing drug and alcohol testing is often seen as a proactive measure to ensure workplace safety and fulfill a duty of care.
  • While ensuring workplace safety is paramount, employers must balance this with the individual rights and privacy of employees. Any drug and alcohol testing you implement and corresponding policies and procedures must align with these privacy regulations to avoid legal implications.
  • While you may be legally entitled to implement workplace drug and alcohol testing, get the buy in of employees first. Employees should be aware of the purpose, methods, and potential consequences of testing. In general, employees will be on your side because testing will help them do their job and get home safely.
  • If you’re considering implementing drug and alcohol testing you must develop clear and comprehensive policies and procedures first. These policies and procedures will outline the purpose of testing and contain comprehensive details about aspects such as methods and consequences. Again, make sure you communicate and educate these policies to your employees.
  • There are different methods of drug and alcohol testing, including urine testing and saliva testing. The choice of testing method can impact the legality and acceptance of the process. For Integrity Sampling, we always recommend saliva testing to our clients.
  • There are also different reasons or methodologies for testing. Drug and alcohol testing may be conducted based on reasonable suspicion, after accidents, during pre-employment processes or as part of a random testing program. Your policies and procedures should provide thorough details about your methodologies.
  • A comprehensive drug and alcohol testing policy should not only focus on punitive measures but also incorporate avenues for rehabilitation and support. Employees who test positive may have underlying issues that need addressing. Providing assistance and support can be crucial in fostering a workplace culture that values employee well-being.
  • Having thorough and detailed policies and procedures and following these religiously will protect you from potential legal challenges that may arise from drug and alcohol testing. Ensuring that testing processes are fair, consistent and compliant with relevant laws is essential. If an employee is dismissed based on a positive test result, the legality of the dismissal may be subject to scrutiny. Adherence to your drug and alcohol policies and procedures, as well as fair dismissal procedures, is paramount.
  • Finally, workplace drug and alcohol testing policies should be regularly reviewed and adapted. Keeping policies up-to-date helps maintain legal compliance and ensures that testing procedures align with the evolving nature of the workplace.
