Fuller is, a the title suggests, the largest evangelical Christian seminary in the world. Now, given, that doesn't necessarily say much, when the field is as small as it is for graduate and post-graduate level theological education, but it is something. The seminary tries to encourage all of their employees, even a simple part-time, work-study library assistant like me, to do things to become, and/or stay healthy in all areas of life. The library is a relaxed place to work, and my direct manager is one of the better ones I have had the pleasure to work with. My co-workers are friendly and help each other when necessary/ possible, so the environment is pleasant.
The hardest part is the monotony factor, because it is literally doing the same thing day after day.
The best part of the job is the scheduling flexibility, since I am also a masters' student at Fuller.
