The Unauthorised absence heat map is used to highlight patterns of unauthorised absence for an employee grouped by the day of the week.

It is displayed on the employee card of each employee and is only used for time off types where Authorised is set to 'No' in the time off settings for that type. 

You can adjust the period over which the heat map looks in Time-off settings using the Absence rate period and also can choose to turn the heat map on and off in Display settings.

An example of a heat map might be:

The heat map uses four colours to highlight potential issues with an employee's absence. The individual colours are triggered based on a percentage of the total number of possible days the employee could have worked in the indicated period in a similar way to the absence rate. In each case, when you hover over the relevant day a tool-tip will appear which will show you the actual number of instances.

The four colours used are:

Grey - non working day

Green - absence for that is less than 2.5% of the total possible working days

Orange - absence for that is less is between 2.5% and 4.9% of the total possible working days

Red - absence for that is over 5% of the total possible working days

For example, in a "typical" working environment where an employee works 5 days per week over 52 weeks of the year this works out as 260 days per year.

Using the above calculation, any given day would trigger as ORANGE when the employee has more than 6 instances of unauthorised absence on that day and RED when the employee has more than 12 instances of unauthorised absence on that day.
