Social Comparison, Inequity, and Absenteeism among Bus Drivers

In this study, absenteeism among bus drivers is predicted on the basis of equity theory and social comparison theory. The number of objectively recorded absence spells (up to a maximum of 14 calendar days) is assessed in a sample of 116 bus drivers from a transport company in the Netherlands. Using the program LISREL, a social psychological model is developed (i.e. tested and revised). The study demonstrates the impact upon absenteeism of two social factors: (1) conflicts with superiors, which are associated with drivers' perception of investing more in the exchange relationship with the company than they receive in return; and (2) the perceived norms of colleagues regarding being absent from work. In addition to their impact upon absence behaviour, both social factors also seem to influence the personal norm regarding being absent. Unexpectedly, the personal absence norm is not significantly associated with absence behaviour. It is concluded that equity theory and social comparison theory enhance our understanding of absenteeism among bus drivers.
