Interpretation

A high illness rate may be interpreted as an indicator of a heavy workload, bad working conditions, dangerous working environment, low employee satisfaction, and so on. As a simple key figure it can be used for planning purposes, for example, to shift resources from one area into an area with a high Illness Rate. An analysis of the illness reasons or causes must include other factors as well. For example, a high overtime rate combined with a high number of accidents may indicate the reasons for an increase of the illness rate.
