Beware the fine line between insubordinate threats and actual violence

It’s up to HR to keep an eye out for workplace discord that could erupt into violence. Train supervisors to be alert for obvious insubordination. An employee who refuses to follow directions or openly challenges authority other than through reasonable channels may be on the verge of escalating insubordination into violence. In turn, HR should have a plan to intervene, either through appropriate internal discipline or by referring the matter to the police.
