Working onsite at the various universities is good, just that there is a lot of bureaucracy from the main corporate office. They are going non-profit and will be under new ownership this summer, but I feel the culture that has been there will still remain the same. My understanding is that there will not be much changes with this transition.
You feel somewhat Isolated from management, unless you work directly at the corporate office which I can't speak for experience on that. Most of my management that I talk to is usually over phone conferences or emails. Any instructions for a project that come from them always seem confusing, making it harder to do a task in a timely matter. Some people, including management, have difficulty remembering meetings and notes that happen a few months ago .
Overall, it is not a bad company based on my experience. Just be ready to deal with convoluted procedures that affect how you do your job well.
Paid time off, University staff where I work at are all nice and understanding!
Lower pay, no opportunity for advancement, corporate bureaucracy is convoluted with their polices and procedures.
