Organizational change, health, and sick leave among health care employees: A longitudinal study measuring stress markers, individual, and work site factors

This controlled longitudinal study was conducted to investigate the effects of organizational change on employees' self-reported health, work satisfaction, work-related exhaustion, stress, and sick leave. The population consisted of 226 employees at T1 and 198 at T2, divided into a study group affected by organizational changes, and a reference group not affected by them. Group differences for the outcome measures self-rated health (SRH), work satisfaction, work-related exhaustion, and hormones associated with stress were analysed using a two-factor ANOVA design for repeated measurements. Our findings showed no significant differences, either across time or between groups for SRH, work satisfaction, and work-related exhaustion. However, we did find significant change across time and between groups for the recovery hormone DHEA-S. Days of sick leave increased by 7% for employees in the study group and by 2% in the reference group. Serum cortisol showed significantly decreased levels across time but not between groups. The decreased recovery potential in the study group might have long-term health implications. The study points to the importance of looking at the impact of organizational change on employee well-being from a number of perspectives, such as self-reported health parameters, registered sick-leave data, and biological stress markers.
