Pros
People at Brown are genuinely smart and interesting and mostly very kind. Many lectures and events on campus are free, so if you want to immerse yourself in the intellectual community, it's easy to do so. The benefits are fantastic, particularly excellent health insurance, and at lower salary levels, you contribute very little towards the premium. Plus employees get lots of vacation/sick time, "summer hours," and the week off between Christmas and New Year's.
Cons
Salaries are quite low, even compared to other area universities and research . And there are few opportunities for career advancement. Academia has very few structures in place to actually promote good employees and weed out the deadwood or incompetent. Plus Brown itself still has a bit of an identity crisis as it wants to be a world-class university but until recently it was mostly a residential college so it has kind of a provincial attitude about certain things, particularly in admin units. Department Chairs are not HR managers, and sometimes can't recognize when someone really isn't pulling his or her weight - they aren't interested in investing their limited time to figure out systems and to advance careers for those who are actually competent. HR people are helpful but operate on a corporate model, and many academic jobs don't really fit into neat little boxes.
