Drug and/or alcohol testing in the workplace is complex. But employers are generally permitted to ask a worker to submit to a drug and/or alcohol test if the worker has been in a serious safety incident. So employers should have written procedures in place spelling out which safety incidents trigger a drug and/or alcohol test and the procedures for such testing.
HOW TO USE THE TOOL
Adapt this model procedure for your workplace, existing drug and/or alcohol testing policies and the terms of any collective agreement, if appropriate. Then train all workers and supervisors on it.
