Pros
WWU is one of the best employers in Bellingham. Compensation is (so I hear) low relative to other universities, but for Bellingham, it's very good. For benefited employees, the benefits are great, especially if your position is exempt. Staff in many cases have it better than faculty when it comes to overall compensation (other than tenured faculty of course). Work-life balance is understood, so it's a great workplace for someone with a family.
Cons
The normal schedule is 8AM to 5PM. That can be difficult for people with young children in school; but with the right supervisor and the right kind of position, a different start time can often be negotiated. Many positions are part-time and have no benefits; but positions open up quite frequently and once you're "in" at Western, you're encouraged to apply for positions when they become available.
