This study is on toxic leadership, focusing on what it is, and how to either stop or prevent toxic environments. This topic was chosen because the author is about to assume command of a military unit and wanted a good understanding of how to deal with toxic environments if they exist in his new role. Methods of research focused on the command climate surveys, which is a requirement for a commander to initiate every two years, and upon assumption of command. Research was focused on results and if the results could be tied to if a toxic environment exists. Results concluded that the climate survey targets areas that directly correlate to toxic environments. It also concludes that toxic behaviors can spread rapidly. Even organizations with positive climate, can rapidly become toxic, which is why it is a continuing process to prevent and stop toxic behaviors from spreading.
