How do I see a volunteers schedule from the Organization level?

As an Organization Manager, you can see a user's schedule from their profile pop-up. From the Organization's staff list, a Manager can click on a user's name to open their profile and then navigate to the Schedule tab from the left-hand nav bar.

By default, the Schedule tab will show Shifts for Today&Upcoming, but Managers can switch to show Past or All shifts using the dropdown date range selector.
