Drug testing in the workplace: What’s legal, what’s fair, what works

Drug and alcohol testing can be one of the most complex and sensitive areas of workplace health and safety. When is it lawful? What kind of testing is allowed? And how do employers balance safety, privacy and employee rights?

EMA Legal Counsel Mauro Barsi joins Kevin Chambers to unpack what employers need to know about drug testing in the workplace. They cover when testing is appropriate, the four recognised types of workplace drug testing, what “reasonable cause” really means, and what to do if an employee refuses a test.

The conversation also explores safety-sensitive roles, post-incident testing, medicinal cannabis, testing methods, and why having a clear, well-consulted policy is essential.
