Your Helpers cannot view Categories unless you change this option on your SETTINGS>Global Helper Permissions
Two things need to be set to allow Helpers to see the Category designations you have set for shifts:
- The option on your SETTINGS>Global Helper Permissions page - Be sure the option: "Can see CATEGORIES" is set to "Yes"
- The coordinator Calendar WEEKLY Schedule View controls the look of the Helper "Everyone's Schedule" View. Use the Change Layout link on your Calendar Weekly view to set how you want the Helpers to see the schedule.
Check off the option to "Show Category/Positions" and then choose whether you prefer to have the shifts displayed in groups sorted by Position or Category (you might want to try both to see which you prefer).
The view the Main Coordinator creates using the "Change Layout" links set up how Helpers see that view in their accounts.
