The ease of use, the ability to track employee's time off, the ability to add notes to leave requests and the ability to attach documents/files to leave requests. I dislike that there is no option to have the system log in automatically when employees start their shift. This would be very helpful to have for any new hires who are not familiar with how the system works. We use this software to keep track of all absences and time off requests from our employees. It has been very beneficial to us as it allows us to easily see what time they will be working and when they plan to take off.
