Can my employer test my urine? Saliva? Both?

Introduction

This article delves into the intricacies of drug testing in the workplace, examining the methods employers use, the legal basis for testing, and potential ethical concerns. It aims to clarify the rights and obligations of both employers and employees in this context.

Understanding the Legal Framework

The authority for workplace drug testing typically stems from the Work Health and Safety Act (harmonised across multiple states between 2011 and 2022). Employers have a duty of care, and workers are obliged to comply with reasonable testing directions per Section 28 of the Act.

Testing Methods

Different industries adopt various drug testing methods, with some relying on urine tests, saliva tests, or a combination of both. The choice often depends on the nature of the work and the potential risks involved. For example, professions in policing/defence environments require testing moreso to promote integrity than for any real risk mitigation, this is why NSW Police use hair follicle testing. High-risk professions like healthcare (where the risk is to the patient if a worker is on drugs), construction, transport and aviation may require stringent testing due to safety concerns.

Legal and Ethical Considerations

A key legal consideration emerges from the case of Shannon Green v Lincon Logistics Pty Ltd, where the Fair Work Commission questioned the reasonableness of changing the testing matrix. The prevailing sentiment in the absence of higher court rulings suggests that altering the testing matrix may be deemed unreasonable.

Ethical concerns arise from the detection window of different testing methods. While oral fluid tests may detect recent drug use (4-24 hours), urine tests can reveal drug use over a more extended period (up to weeks). Northern Rivers WHS emphasizes that an employer's interest should focus on impairment during working hours rather than activities in an individual's personal time.

Lack of Clear Legal Precedent

As of the latest update (20.01.2024), there is no High Court or Federal Court ruling specifically addressing workplace drug testing. The Fair Work Commission remains the primary federal authority handling occupational drug testing cases. The absence of a comprehensive legal framework leaves room for interpretation, making it challenging to provide definitive answers on certain aspects of drug testing.

Conclusion

In conclusion, while employers have the right to conduct drug tests, the specifics depend on factors such as industry standards, workplace policies, and the reasonableness of testing methods. The ethical dimensions, particularly regarding the detection window, add complexity to the issue. Until a comprehensive legal framework or court ruling emerges, Northern Rivers WHS suggests caution in engaging in multi-matrix testing for the same matter. The lack of a caselaw does not mean that what you are doing is legal - just the opposite, you could be the guinea pig that a court chooses to make an example out of.

Drug testing at work is generally legal provided:

1. There is a policy in place clearly outlining the testing process and matrix, and

2. It has been communicated to all workers, and

3. The testing complies with Australian Standards (AS/NZS 4308 or 4760).

If you feel you have been subjected to an unfair/unreasonable drug test, you need to consult with an employment lawyer immediately as there is usually a tight window (28 days) to commence an action against a company/employer. If you miss that window, you'll have to ask the court to make an exception to hear your case which is uncommon.
