This study reviews different typologies of toxic leaders in organizations-from bullies to narcissistic leaders. Unfortunately, toxic leaders are a painful but common reality in many organizations. Their destructive behaviors and dysfunctional personal characteristics often generate enduring poisonous effects on those they lead. They are identified by selfish outcomes in their decision-making and how they leave subordinates worse off than when they began. What distinguishes excellent from average managers is their ability to effectively manage dysfunctional leaders in the workplace.

The author suggests some effective coping strategies to identify, address, and transform toxic leaders and workplaces
