Several employees are offering shared services - at the same time. When this is the case, you’ll need several calendars, as one planner equals one employee. E.g. Ali, Per and Kari work in the lab and want to offer appointments at the same time. Ali does a vaccination at 08.00, Per does a wound care at 08.00, and Kari takes a blood test at 08.00. Each will need their own calendar.
