Pros
I found events at other universities with whom we partnered to be very professional, and found an extremely cordial staff to work with. I worked in special events for one of the graduate schools, and found my clients to be very engaging, and the work interesting and enjoyable.
Cons
I had trouble with my benefits, hiring package, and numerous errors in payroll, all of which were resolved by the company. However, as this happened frequently, I found this a bit bothersome. The campus director was very unpleasant to work for, and was not well regarded by the other directors who worked for her. It was not a very pleasant atmosphere. I didn't feel like I worked for very honest people--however, I think this was an issue at this particular institution.
