SOCIAL INTERACTIONS AT THE WORKPLACE: EXPLORING SICKNESS ABSENCE BEHAVIOR.

We investigate whether a worker’s sickness absence is affected by her colleagues’ absences from the workplace. The analysis is based on unique matched employer-employee data for Norwegian schoolteachers for the period 2001 to 2006 with information on different types of absences and multiple teacher and school characteristics. Using different approaches where methodological problems such as the reflection problem and intra-group correlation are mitigated, we look for evidence of social interaction effects. Our results show that the significance of the social interaction effects critically depends on our ability to control for unobserved school characteristics.
