Stress is symptomatic of a demand for change in the environment, and it is a natural phenomenon. When it is mismanaged, it can be harmful. The three sources of stress are personal, environmental, and organizational/social. The four types of stress are hyperstress, which results from being overloaded with change; hypostress, which is produced from being underloaded with change; eustress, which comes from favorable or positive changes; and distress, which stems from unfavorable or negative changes. A police manager is sure to experience all four types of stress, especially hyperstress, due to the nature of the job. Distress can seriously reduce the effectiveness of a police manager, so the police manager should be alert for the general and specific symptoms of distress. The manager should maintain a program of wellness by recognizing that he/she is responsible for his/her health, collecting reliable data on his/her stress level, and designing and using a custom-designed plan for wellness. 15 notes, discussion questions.
