Pros
As with any academic institution, a lot depends on what department you work in. Also, as with any school, there is often an iron curtain feel between the faculty and staff. Having worked in a supported role (staff) for six years, I can say it was over all a good experience. Most (not all) people are generally friendly and the work hours are good.
Cons
As I said, a lot depends on which department you work for. My department was great, but it served the rest of the campus, faculty and staff. With any service role you are going to come into some rude people. Overall though, it was disappointing to see that the faculty tended to be the rudest, though some were very nice. The faculty are under a lot of pressure at DTS, but many of them have taken an elitist attitude which does not help a ministry environment. DTS is a personality-promotion environment. In other words, people are given position and power because they are friends with a leader, or through other political maneuvering. This it how it works: there are many jobs at the school that require skills sets that have little or nothing to do with the skill set the school teaches (theological studies). But, because the school's leadership's skill set is theological studies and teaching, they tend to promote people who have that same skill set, even to positions that have little to nothing to do with that. What DTS has ended up with is an environment that has more respect for people who can politically maneuver themselves (play politics) to positions they might never acquire outside the school. Some of the staff are vastly under-qualified to do their job. Though, I don't expect DTS is any different than other theological schools in this way. The compensations, both in salary and benefits, at DTS is poor. The HR department maintains that compensation is competitive, but that dose not mean it is reasonable or even livable.
