The researchers analyzed 546 instances of sick leaves taken by 432 Swedish workers at six different workplaces. In the first day or two of sick leave, the researchers telephoned the people who had called in sick and asked them about several different aspects of their work situation. The findings:
- People who called in sick were more likely to have experienced psycho-social problems at work in the past few days than people who did not.
- The most common psycho-social problem reported by the people who had called in sick was a 'very stressful work situation, indicated by more tasks, fewer staff, or a larger field of responsibility than usual.'
- Problems in one's relationships with colleagues and bosses were also associated with a higher incidence of sick leave.
- Other stressors, such as harassment, discrimination, and being assigned 'unpleasant tasks' were not associated with an increased incidence of sick leave.
One explanation for the findings is that employees, when faced with a very stressful work situation, either consciously or unconsciously used the sick time for a 'mental health day' so they could face their jobs relatively refreshed after sick leave. It could be that stressors such as harassment and being assigned unpleasant tasks did not encourage people to call in sick because a few days' reprieve might not make much difference-the tasks or the discrimination would still be there when the worker returned.
Another explanation is that those in highly stressful jobs are more likely to get sick. This wouldn't be the first study to find a correlation between stress, the immune system, and illness. The most common reasons workers called in sick were colds, flu, and headaches.
