The correct answer is C. Assign a higher priority to the time calculation for hours worked on the seventh consecutive day.

In Workday Time Tracking, calculation priority determines the order in which time calculations are processed. When multiple calculations depend on each other, the prerequisite calculation must execute first so that its results can be used by subsequent calculations. In this scenario, the first time calculation identifies when a worker reaches a certain number of consecutive days worked. The second calculation specifically evaluates hours worked over 8 hours on the seventh consecutive day.

For the second calculation to work correctly, Workday must already know that the worker has reached the seventh consecutive day threshold. Therefore, the calculation that evaluates hours beyond 8 on that seventh day must run after the initial consecutive-day identification calculation. This is achieved by assigning it a higher priority value, ensuring it processes later in the calculation sequence.

Options A and B are incorrect because Workday does not automatically determine priority between time calculations. Administrators must configure priorities manually. Option D is also incorrect because Time Calculation Groups control eligibility and grouping, not execution order.

Thus, assigning a higher priority to the seventh-day overtime calculation ensures the correct processing sequence and accurate tagging of hours.
