Changing a coworker's schedule the day before their shift is a decision that appears simple for internal organization, but its effects rarely limit themselves to the day of the change. The swap forces the worker to reorganize transportation, childcare, medical appointments, and even their own rest, spreading consequences throughout the following days.
In workforce management, schedule predictability is already treated as a well-being factor as relevant as workload and physical safety. A survey by The Shift Project, linked to Harvard University, showed that service sector workers subjected to unstable schedules report more difficulty sleeping well, taking care of personal and family matters, and getting time off when they need it.
A study conducted by researchers from the University of California identified that workers given two weeks or more advance notice about their schedules were significantly more likely to report happiness than those who received their schedule with less advance notice.
