Can I cap the number of days that can be taken off work by absence type, i.e. to prevent the employee from exceeding their entitlement?

It is not possible to set a maximum number of days by absence type. However, it is possible for system administrators to insert a note by absence type. As such, a note can be published explaining the maximum number of days for an absence type. Go to the left sidebar > Click on ''Administration'' > Click on ''Absences'' > Click on ''Types'' > Select the absence type by click on it > Click on ''Notes'' > Insert a note.
