Drug abuse affect on the workplace

Drug abuse can have a devastating effect on more than just the user. It can cause decreased productivity, increased absences and even workplace accidents. An injury that happens while a worker is under the influence of drugs is not automatically excluded from workers’ compensation, but WorkCover will look at whether the work was a significant contributing factor, an injury caused by a worker’s serious and wilful misconduct is only compensable in limited cases, and intoxication can reduce damages in a common law claim. employers and employees alike can work together to keep their workplace safe and drug-free!

Create a workplace drug and alcohol policy

The first step that employers can take is to create a drug-free workplace policy. This policy should be clear and concise, and it should outline the consequences for employees who are found to be using drugs and specify whether drug testing will be a condition of employment. Employees must be aware of this policy so that they know what is expected of them.

Do employees have to tell managers what medications they are on?

When it comes to prescription medications, employees must inform their manager if the medication has the potential to adversely affect performance or if safety is an issue. They are not required to explain the nature of any medical condition or the reason they are on a particular medication.
