[Perception of work load among female workers as an indicator of work stress and chronic fatigue].

The aim of the present paper was to determine the trends and extent of the effect of primary parameters of female workers' workload on the feeling of fatigue caused by a day's work and on chronic fatigue. The study comprised female workers 138 of whom performed fynamic-static work and 117 were busy with static work only. Methods used for measuring both the workload and fatigue were subjective. The experiments demonstrated that the extent of different types of workload was, according to workers, not always related to an increased fatigue caused by day's work and chronic fatigue. The effect of workload parameters is modified by the type of work performed and characteristics of workers groups. Time pressure turned out to be a negative factor affecting an increased fatigue caused by a work's day. Physical workload is an important indicator of an intensified fatigue resulting from a day's work as well as of chronic fatigue of female workers performing dynamic work. Physical workload has not the same effect on the other group of workers. Negative influence of workload parameters revealed itself mainly in relation to day's work fatigue, and to a lesser degree, in relation to chronic fatigue.
