The sources of burnout

There are several sources that leads to burnout. One source refers to insufficient clarification of roles and responsibilities. Normally staff feels caught in the middle when receives conflicting messages from different superiors, when requirements exceed the resources and skills or when the tasks do not coincide with their aspirations and skill.
If we see some requirements as unclear responsibilities it will be obvious the conflict between them and resources.
Lack of adequate information on the tasks to be fulfilled and so their failure will result in a decreased self-esteem and affect the sense of personal fulfillment.
Another source of exhaustion refers to the blocking of creativity in work, exclusion from decision-making cycle and limitations on the discretion of work. The unknown always causes alarm and standoff from taking decision that concern personal staff can be stressful because they do not know what to expect.
Nobody knows someone's job better than the person concerned, and organizations should be open to their suggestions and to enable them to improve work environment in certain limits.
Paradoxically, a source of exhaustion can be boredom as the starting point. The circumstances leading to the emergence of boredom relates to the existence of a low variety of tasks and opportunities for expansion of knowledge. Thus, employees become uninterested in their job, which will become for them a source of conflict. And this scheme fits in the scheme mismatch between resources and requirements.
