Workload

A working stress is the personal impact of a workload from a work activity on the performers. This effect is dependent on the performance of the work and person of previous loads already. Therefore, in the same work loads individually and temporally different effects are to be expected.

Tolerable stress levels are determined by the duration power limit. A stress that is above this limit, calls in the affected organs or organ systems has resulted in fatigue. As duration power limit applies in this context, the maximum power that while the company usual daily work related - 8 working hours - in the long run is possible and up to one additional recovery is not necessary (see also normal power).

In relation to the physical stress, for example, results in an average workload, such as lifting a 25kg carrycot with an average working person to a higher stress than with a higher than average and trained working person. Difference does it also, whether the work this person makes in a rested state, or has previously been often performed this work. See also Key Indicator.

For the investigation of psychological stress and strain the social psychological theory of stress is considered appropriate frame of reference: According to the building on the Stressthorie Person - Environment Fit model ( person-environment matching model ) performs a gap between perceived job demands on the one hand and personal work skills and job requirements, on the other hand a state of psychological stress on health disorders.

The work stress is an essential criterion in the allocation of work tasks to performers (see also: work structuring). An important criterion is continuous stress limit, so the amount of stress that currently remains the same even with continued duration of a burden and not constantly increases (see also: continuous power limit).
