Impact of worktime arrangements on work-home interference among Dutch employees

Objectives This study examined the effects of different worktime arrangements on work-home interference while taking into account other work-related factors, private situation and health status, explored gender differences in this relation, and examined reciprocal effects between workhours and work-home interference. Methods Data from the Maastricht cohort study on fatigue at work were used with 8 months of follow-up (N=6947 at baseline). Results Worktime arrangements were related to work-home interference among the men and women, even after control for confounding. As compared with daywork, baseline shiftwork was associated with higher work-home interference over time. Within daywork, full-time work was prospectively related to higher work-home interference than part-time work was. For full-timers, baseline overtime work, hours of overtime work, change in number of workhours, and commuting time were related to higher work-home interference over time, whereas compensation for overtime work, familiarity with work roster, ability to take a day off, and a decrease in workhours at own request were associated with less work-home interference. For the part-timers, baseline overtime work and commuting time were related to higher work-home interference over time, whereas compensation for overtime, flexible workhours, and ability to take a day off were protective against work-home interference. Reciprocal relations between work-home interference and workhours were also found. Conclusions Worktime arrangements are clearly related to work-home interference. Because reciprocal effects exist as well, important selection processes may exist. Nevertheless, specific characteristics of worktime arrangements could constitute useful tools for reducing work-home interference.
