The correct answer is D. Ad hoc schedule changes .

In Workday Time Tracking, when a manager assigns a work schedule to a worker using the Assign Work Schedule task, that schedule becomes the worker’s standard planned schedule. However, Workday also supports temporary or date-specific exceptions through ad hoc schedule changes . These changes are designed to override the normal assigned schedule for a particular day or period without replacing the worker’s overall schedule assignment. This is useful when a worker has a temporary shift change, a one-time different start and end time, or a short-term adjustment due to business needs.

This is why ad hoc schedule changes are considered the override mechanism. They sit on top of the normal schedule assignment and take precedence for the affected dates.

The other options do not override the assigned work schedule itself. Flextime bands provide flexibility around expected start and end times, but they do not replace the assigned schedule. Schedule deviation calculation is used to compare reported time against schedule expectations and identify variances; it analyzes schedule differences rather than overriding the schedule. Work schedule eligible rules determine which workers can receive certain schedules, but they do not act as overrides after assignment.

So, the component that overrides an assigned work schedule is Ad hoc schedule changes .
