Most regular statistics of working time and working time
arrangements are based on information collected through
Labour Force Surveys or through Establishment Surveys.
However, it has for a long time been argued that to be
reliable and valid the measurement of actual time worked
has to be integrated into a framework which accounts for
all time use activities. By doing so one might be able
to not only (i) improve the precision and reduce biases
in the measurement of total time worked, but also (ii)
obtain estimates of the scheduling of work activities,
and (iii) obtain estimates for the way time is used at
work, which are the time use issues of interest to users
of statistics on working time. pdf
