Early Warning Signs of Violence

Text 1:  Type 3 Violence:  Early Warning Signs.


Often, when we hear media reports of employees who “went crazy” in a workplace, killing and/or injuring co-workers and managers, we think that the person simply “went over the edge,” that there were no clues.

This is not true.  Not only are there many warning signs, these warning signs are frequently given.  Some warning signs are subtle, but others are obvious.  Following is a list of warning signs to look for in your employees.
