Which tab in the calendars application is used to view, add, modify, and delete work periods?

The Work Periods Tab is specifically designed to manage work periods within the calendars application. This tab provides users with the functionality to view existing work periods, as well as add new ones, modify current entries, and delete any work periods that are no longer needed. The focus of this tab is directly on the scheduling of work hours and periods for resources, making it the essential tool for any adjustments related to work timings.

In contrast, the Shift Schedules Tab primarily deals with predefined shifts and their configurations for employees, while the Availability Tab focuses on employees' available times rather than the specific work periods themselves. The Labor Allocation Tab addresses the distribution of labor resources across various tasks or projects rather than the management of work periods. Therefore, the Work Periods Tab is the appropriate choice for activities concerning work period management.
