Occupational Stress is stress at work. Stress is defined in terms of its physical and physiological effects on a person (or thing). Stress is mental, physical or emotional strain or tension or it is a situation or factor that can cause this. Occupational stress occurs when there is a discrepancy between the demands of the environment/workplace and an individual’s ability to carry out and complete these demands. Often a stressor can lead the body to have a physiological which in turn will result on a strain on a person physically as well as mentally. One of the main causes of occupational stress is work overload. Occupational stress is often caused by an increased workload without the addition of employees to take on that additional work. Instead the increased amount of work is given to the current employees to finish in the same time span that they would be asked to finish their regular or standard workload.
