Pros
It's a university. Some departments are okay. The Kalamazoo Promise might be nice, if you live in Kalamazoo. Depending on department, it can be a stepping stone to a better job. It is only a couple hours from Chicago, and it is on the Amtrak line. The library is adequate. There are some good students amongst all the partiers. Convicted drug dealer Tim Allen is an alumnus. The University president once appeared on convicted drug dealer alumnus Tim Allen's TV show. You are only 45 minutes from Lake Michigan. The pay is about average for the size of the University.
Cons
Western wants to be a research university on a teaching university budget. Nominally the teaching loads in research departments are compatible with research time, but the class sizes are so big it cancels out. Different departments do not trust others. The general intellectual atmosphere of the University is very poor. Hiring and tenure policies are biased if you are not a member of a specifically recruited group. For a small town with a relatively large university, Kalamazoo does not feel like a college town. There are few nearby neighborhoods that are attractive for faculty to live in. Spouse employment opportunities are limited.
