The right end of the spectrum consists of such acts as overt violence causing physical harm, nonfatal assaults with or without weapons, and lethal violence. Moving toward the left end of the spectrum, behaviors become less physical and more emotional/psychological. These include disruptive, aggressive, hostile, or emotionally abusive conduct that interrupts the flow of the workplace and causes employees concern for their personal safety. Bullying, stalking, and threatening appear on this end of the spectrum. At the far left end are behaviors of concern, including nonfatal or lethal ones.
