Occupational stress
Occupational stress is stress related to one's job. Occupational stress often stems from unexpected responsibilities and pressures that do not align with a person's knowledge, skills, or expectations, inhibiting one's ability to cope. Occupational stress can increase when workers do not feel supported by supervisors or colleagues, or feel as if they have little control over work processes.
Models of Stress
Because stress results from the complex interactions between a large system of interrelated variables, there are several psychological theories and models that address occupational stress.
Person Environment Fit Model: This model "suggests that the match between a person and their work environment is key in influencing their health. For healthy conditions, it is necessary that employees’ attitudes, skills, abilities and resources match the demands of their job, and that work environments should meet workers’ needs, knowledge, and skills potential. Lack of fit in either of these domains can cause problems, and the greater the gap or misfit (either subjective or objective) between the person and their environment, the greater the strain as demands exceed abilities, and need exceeds supply. These strains can relate to health related issues, lower productivity, and other work problems. Defense mechanisms, such as denial, reappraisal of needs, and coping, also operate in the model, to try and reduce subjective misfit"
