Viewing the staff assigned to a specific instance of an activity is very easy. Simply navigate to Check In and find the date, activity, and time slot you wish to view. Select that activity and you are presented with the activity manifest.
In the above fictional example, you can see that "Steve" is assigned as the only staff member for the "Monday Morning Coffee with Steve" activity for the 7-9 am time slot. We can also see the roles of the staff listed. In the above example, Steve is listed as the Bartender and Lead Guide.
