On‐Demand Schedules, Worker Absenteeism and Patient Dissatisfaction in Home Care Services
Journal of Operations Management, Volume 71, Issue 8, Page 1090-1114, December 2025.ABSTRACT Service companies often adopt on‐demand scheduling to balance labor costs and fluctuating market demand. However, research shows that such practices can reduce worker productivity and retention. In this study, we examine how on‐demand scheduling affects two critical outcomes: worker absenteeism and patient dissatisfaction.
