The book details eight major categories of behavioral clues to violence and includes anecdotes from work settings to help managers and others identify potentially violent employees. Eight patterns of high-risk behavior include employees who: (1) act primarily on the basis of their emotions and impulse, overreact, and have outbursts of rage; (2) see no continuity between actions and results, repeat the same mistakes; (3) focus almost exclusively on their own needs, blame others, seek immediate gratification; (4) approach life inflexibly, demand perfection; (5) behave in passive-aggressive ways, manipulate others; (6) avoid reality, exaggerate credit and minimize blame, lie and deceive others; (7) change their behavior suddenly, dramatically or for the worse; and (8) behave in remote or withdrawn ways, are obsessed with plans, are isolated and cannot concentrate on the present.
