When I worked for UPX they were expanding all over the country. Now, just a few years later, they are closing campuses outside of Arizona left and right. There have been frequent lawsuits against the company for their business practices, and I have heard stories (can't verify to be certain) that some employers do not consider their degrees as being legit.
The staff at UPX were great professionals (at least at the campus where I worked). The problems stemmed from the home office in Arizona and the regional office in Kansas City. Frequent changes to business practices, refusal to adjusting schedules for both family issues (needing a parent home with a child) and for meeting academic needs (they pressure you to enroll in a degree program then refuse to adjust the work schedule so you can go to class), and lack of advancement opportunities are samplings of the plethora of issues at UPX.
Again I haven't work there in some time, but when I did it was not the best environment to work in. As I understand it now based on a couple friends I know working on a different campus, it's not much different there either.
no flex scheduling, strict quodas, weak leadership
