"Workplace violence is something employers are acutely aware, thanks to a few unfortunate and well-publicized incidents over the past few years and changes in laws that have partly been spurred by such incidents. Legislation such as Ontario’s Bill 168 has placed a greater responsibility on employers to make sure employers are safe not just from occupational accidents, but threats from other people — whether co-workers, customers or other outside individuals.
In order to ensure their workplaces are safe for employees, employers must crack down whenever workplace violence or threats happen. But what is the right way to respond? Are we sensitive enough to the threat of violence that termination should pretty much be automatic, or should there be levels of progressive discipline like for other forms of employee misconduct?"
