Step-by-step explanation:
According to the textbook, the main reason why stress is related to increased workplace accidents in any job is b. impaired concentration. When employees are stressed, their ability to concentrate on tasks can be negatively impacted, leading to a greater likelihood of accidents. Occupation-related stressors, such as a heavy workload, excessive paperwork, and frustrating work conditions, can significantly affect an employee's mental state. Moreover, job strain, which is a combination of excessive job demands and limited control over the work environment, contributes to a decline in job satisfaction and increases the chances of job burnout. The more stress experienced by a worker due to these stressors, the greater their sense of vulnerability, which is linked to lower job satisfaction.
