What is stress of work and from which arise?

With simple language, job stress can be understood as a situation where a person faces the task or job that may or may not yet be reached by his ability. If a new person's ability to number five, but the ability to face a demanding job with the number nine, then it is very likely that person will be exposed to work stress.
By definition as above, means that causes a person exposed to work stress that there are two.
First, because the management, organization, supervisor, or head that delivers real tasks beyond the capabilities of the employee-owned. This we might call the factual reasons. In fact, people actually get a job or a job that can not be reached by his ability.
Second, because the employees themselves. If he was lazy-masalan, used to think negatively, or not willing to learn, want delicious, yes usually given the task alone was grumbling a bit more, it can not talk, can not afford, and so on. This we might call mental causes. Mentally it employees like that needs to be fixed.
In other words, work stress can arise due to conditions of work (the work condition) and the quality of the worker (the personal quality). If an organization does not have a standard set of traffic management work, this work may be stressful for some people. Management standards that are not obviously work will create conditions in which there are certain people who flooded the job but there is also a crisis task. Management standards that are not obviously work will create conditions in which there are certain people who were given responsibility beyond its capacity. This is related to work conditions.
As related to the personal quality, for example, employees who have the motivation to work good, has a longer career goals, have a stronger need for achievement, and rivals, will be easier to infer the target or task as a challenge (challenge), rather than as pressure (stressful). Work stress experienced was a motivator, driving and trigger performance in the future.
This is different to the employees who have low motivation, have a short career goal (just as long as you receive a salary or origin is not idle), or have a less strong need for achievement. Employees of this second type would be easy to conclude that the task or the target given to him as a stressor. Employees of this type easily dizzy, easily confused, it's easy to feel depressed.
