InLoox reports working days as overbooked (colors yellow, red, and pink) if the effort exceeds the working time.
The effort of the assigned tasks is distributed linearly to the working days in this period according to the time frame that InLoox calculates either from the start/end date of the task, assigned task or project.
Example: The task “Create presentation” has an effort of 5 hours. The start date is today at 2:00 PM and the end date is tomorrow at 11:00 AM. InLoox distributes the effort evenly, allocating 2.5 hours to today and 2.5 hours to tomorrow. Since the working time calendar defines working hours from 8:00 AM to 4:00 PM, today is booked at 37.5% and the following day is also booked at 37.5%. There is still capacity available on both days. The resource can take on additional tasks with a total effort of up to 5.5 hours before reaching 100% capacity.
InLoox can display and highlight absences in the workload overview with an icon.
In order for that to work, you need to add work-free days to calendars or individual people in the InLoox settings. Read the help article Define working hours, calendars and days off.
