Divide days lost to absence by days available to get the absenteeism rate.
The absence rate is the share of total scheduled working days that days lost to unplanned absence represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where lower is better.
