The aims of the study were to explore the effects of the implementation of IT-based tools for planning of rosters among shift workers on work-family-related outcomes and to interpret the results in light of the different implementation processes. A quasi-experimental intervention study was conducted with 12-month follow-up at 14 intervention and 14 reference worksites in Denmark. Workplaces planning to introduce IT-supported self-rostering were recruited, and three different kinds of interventions were implemented. Intervention A and B aimed at increasing workers satisfaction and well-being, while intervention C was designed to optimize the personnel resources. Questionnaire data were collected from 840 employees at baseline and 784 at follow-up. Process evaluation encompassed interviews with about 25 employees and 15 managers at baseline and follow-up. Work-family-related outcomes were work-life conflicts, work-life facilitation, marital conflicts and time with children.

An overall decline in work-family conflicts and increase in work-family facilitation were found in the total intervention group. More specifically, in group B, work-family conflicts and marital conflicts decreased while work-family facilitation increased. In group C, work-family conflicts increased while work-family facilitation and time spend with children decreased, and no significant changes were observed in the reference group and in group A.

In conclusion: An overall positive effect of the implementation of self-rostering was found on the balance between work and private life. However, results from the process evaluation suggested that the organizational aim with the intervention was crucial for the effect.
