Pros

Building my own schedule is very convenient and I appreciate how easy it is to get in contact with employee support on a day-to-day basis.

Cons

It is within each school's right to alter which role you will be filling during an assignment as long as it follows the hours you scheduled for; therefore, making it sometimes difficult to truly predict the nature of your workday.
