Abstract:
A great many papers have been written on the subject
of human fatigue but the complaint is often made in
industry that, while many of these studies may be of scientific
value, it is very difficult to see how they may assist
those who are concerned with the problem in industry, in
particular the time study engineers whose job it is to assess
the fatigue that work involves and to apply the appropriate
allowances.
The object of this paper is to consider the problem
of these allowances (usually termed. Compensating Rest or C.R.
allowances) in the light of scientific evidence. It is not
proposed to refer to previous work that bears on this field
in any specific way, since a paper which did so would run to
considerable length, but rather to evaluate some of the most
important material and to suggest the type of framework for
C.R. allowances that would appear most rational in the light
of available evidence. As this paper is written primarily
for those in industry, knowledge of industrial practices and
terminology is assumed.
