Job stress includes any harmful physical or emotional response occurring because of one’s job, including high blood pressure and insomnia, to name just two. Job stress should not be confused with job challenges. Many people enjoy their jobs, even though they are challenging, because when they meet the everyday challenges of their job the gain a feeling of satisfaction. It is when the challenges of a job come without the authority, tools and support needed to fulfill them, that job stress results. People who are stressed out at work may take their frustrations out on family and friends, may become exhausted, and may feel that they are a failure. If they are in a job that entails risk or high stakes, such as firefighting, law enforcement, or a high level corporate management role, their safety may be risked or their job performance may suffer.
