Some professionals are required by law to report violence or threats of violence. They are called mandated reporters and must, by law, call professional agencies to report even a suspicion of threat risks. You may voluntarily become a mandated reporter by deciding you will take the risk to have someone upset with you if you are overly concerned in error.
The state of our world today suggests that you are best served by overreacting rather than underreacting to your intuition. You will not have to make the final judgment that someone is at risk. You can call in the experts. Mental health professionals, law enforcement, child protective services or other appropriate agencies need to be called in if you ever are concerned about violence. The rule of thumb for managers is that it is better to err on the side of being overly concerned than it is to read a name of one of your employees on the front page the next morning after you did nothing. Memorize the phone number for your local Crisis Hotline. You can always call them for advice and let them make the decision if you are overly concerned. That is what they are trained for and will be available for you 24 hours a day, 7 days a week.
