If you have a lot of student employees or employees with flexible schedules then you know how hard it can be to track who is available to work on which days.  At your option, you can allow your employees to log into the system to view their work schedules and enter their availability information.  It gives you exceptional flexibility without having to spend hours entering information into your computer.  Why do the work yourself when you can let your employees help you?  You'll love the convenience and they'll appreciate the ease in which they can tell you when they can work.
