Schedule Control's Hidden Cost: More Multitasking, More Conflict
In a U.S. survey of 1,100 workers, schedule control was associated with more working at home and more work–family multitasking — and that role blurring suppressed schedule control's benefits for reducing conflict. Workers with schedule control would report even less conflict were it not for their greater exposure to blurring.
What we studied
Most workers who want more flexibility at work have a simple hope: that controlling their own schedule will make it easier to balance work and home. Decades of research has largely endorsed that hope, treating schedule control as a clean resource that reduces work–family conflict. Schieman and Young set out to complicate that picture. Their central question was whether schedule control might carry a hidden cost — specifically, whether the very flexibility it provides increases the blurring of work and family roles in ways that cancel out its benefits.
The study used Wave 2 of the Work, Stress, and Health Survey, telephone interviews with working U.S. adults, retaining 1,100 cases with complete data. Three levels of schedule control were distinguished: no control (43% of the sample), some control (38%), and full control (20%). Two forms of role blurring were the key intermediate outcomes: the percentage of total work hours performed at home (working at home), and the frequency of trying to do job tasks and home tasks simultaneously while at home (work–family multitasking, assessed on a four-point scale from never to frequently). Work–family conflict was the ultimate outcome, measured as a four-item index of how often work cut into family time, energy, home performance, and concentration.
Three nested hypotheses structured the analysis. The role-blurring hypothesis predicted that schedule control would increase working at home and multitasking. The suppressed-resource hypothesis predicted that this role blurring would mask schedule control's genuine benefits — meaning that once blurring was accounted for, schedule control's negative association with conflict should become larger. The buffering-resource hypothesis predicted that schedule control would also moderate two downstream relationships: the link from working at home to multitasking, and the link from multitasking to conflict, with both associations being weaker for workers who had greater schedule control.
What we found
All three hypotheses received support. On the role-blurring side, schedule control was strongly linked to both working at home and work–family multitasking. Workers with some schedule control performed roughly 7% of their total work hours at home, while those with full schedule control performed roughly 20% of their hours at home. Schedule control was likewise linked to more frequent multitasking. Working at home on its own predicted more multitasking as well, and explained part of how schedule control led to multitasking when both were considered together.
The hidden-benefit pattern was one of the study's most striking findings. At first, schedule control looked only weakly or borderline related to work–family conflict. Once work–family multitasking was taken into account, however, the benefit of full schedule control roughly doubled, and the benefit of some schedule control went from negligible to clear. In plain terms: schedule control genuinely helps reduce conflict, but its benefits were being masked in prior research because people with schedule control also multitask more, which raises conflict. The pattern confirms that workers with greater schedule control would experience even less conflict than they do if they were not also blurring work and family roles more often.
The buffering findings added further nuance. The link between working at home and work–family multitasking was clearly weaker for workers with full schedule control than for those with no control. Similarly, the link between multitasking and work–family conflict was clearly weaker for workers with some or full schedule control compared to those with none. Workers without schedule control are most vulnerable, since their multitasking translates most directly into conflict. Workers with control can multitask without as much damage — the flexibility that enables blurring also helps contain its consequences. Notably, none of these patterns differed in any meaningful way by gender, marital status, or parental status.
What this means
The study reframes a longstanding assumption: schedule control is a genuine resource for reducing work–family conflict, but its true benefit has been systematically underestimated in prior research because it simultaneously increases the role blurring that creates conflict. The practical implication is not that schedule control is bad — the buffering findings confirm it genuinely helps — but that granting workers schedule flexibility without also helping them manage the boundary-blurring it enables will leave much of its potential benefit unrealized. Organizations and workers alike benefit from pairing temporal flexibility with deliberate strategies for keeping work and family activities from colliding.
Offer schedule flexibility alongside clear boundary-management support
This research shows that schedule control genuinely reduces work–family conflict — but its benefits are suppressed because workers with flexibility also work at home more and multitask more, both of which raise conflict. Granting schedule control without supporting workers in managing the resulting role blurring captures only part of the available gain. Practical steps include normalizing protected non-work time, discouraging work-task intrusions during family hours even for flexible workers, and offering guidance on separating work and home activities when working from home.
Flexible work policies need a role-blurring component to be effective
Policies that promote flexible scheduling as a work–family solution are on the right track, but the evidence here suggests they will underdeliver without accompanying attention to role blurring. Workers granted schedule flexibility use it to work at home more and multitask more — and those behaviors raise conflict. Effective policy should pair flexibility provisions with norms or guidelines about after-hours availability and the management of work-at-home time, so that the genuine resource benefits of schedule control are not offset by the boundary-crossing it enables.
Flexibility is only helpful if you also manage the blurring it creates
Having control over when you start and finish work is genuinely valuable — this study confirms it does reduce conflict, once you account for how it is used. The catch is that most workers with schedule flexibility also end up working at home more and mixing job and family tasks more often, and both of those habits raise work–family conflict. Recognizing that flexibility creates opportunity for blurring — and that blurring has real costs — is the first step toward using schedule control in ways that actually protect family time rather than slowly eroding it.
