3. 3. Note that the figures relate to the proportion of employees who lost pay for a given reason and not to the amount of time lost due to each reason. They thus measure the frequency of absence and not its severity. But they are only proxies for frequency since they measure the number of employees affected and not the number of times workers were absent for specific reasons. Thus the absolute numbers are of little value, but comparisons can be made between industries on the assumption that the ratio of the total number of absences to the number of workers losing pay is the same in all industries.
