I would echo what Ms. Robinson said, that there are many portions of academic programs in which working is a part of it. Those are arrangements created by the institution in partnership with the different employers. Some of it might be paid, some of it might not be paid, but you're still receiving consideration. You might be getting academic credit, for example. There's a finite amount of time, and you continue your education after it.
