Job Stress and Burnout: "A number of characteristics of the work environment associated with stress have also been identified. One is an excessive workload, not only in terms of number of hours of work expected, but also in terms of the complexity of the work and frequent change in work demands, sometimes associated with rapid advances in technology. Another is ambiguity as to the worker's rights, responsibilities, status, and goals; with such role ambiguity, the worker may experience a sense of loss control and autonomy on the job. Insufficient resources to accomplish the job and administrative indifference or interference also create stress."
