Flag instructors who exceed a defined sub request percentage (e.g., 15%), giving managers an early warning—without blocking emergency requests. This would need to account for how many total classes the instructor is planned to teach per month for example. If an instructor teaches 20 classes per month and managers would want to be alerted once that instructor has planned to sub out 20% of classes, once they have submitted more than 4 sub requests, managers can be alerted by a flag or a notification. This would allow them to take a look and see if that person is going on vacation, has a planned medical procedure, etc. so that they can plan ahead.
