Working on Campus is as you'd expect.
Pros: flexible schedule, very casual
I worked as a tutor, in catering, as a dishwasher, and as a teaching assistant in the introductory biology labs in my years at Concord. No complaints against any of the professors I worked with or the tasks I was given. Living on campus and working with labs and faculty within the department of your major made everything for scheduling and transportation, etc. etc. very easy, very cheap. Any difficulties only came from the occasional issue with the students you were there to help, as you'd expect. For the most part, it was pleasant to work with the students and always pleasant working with the professor. The job was part-time minimum wage, thus no benefits and no real advancement. This is a job you take for a little extra money and that fits in your schedule, and for the sake of experience.
