Pros
Ok benefits. Flexible working hours in some situations. Possible to transfer to different departments on campus (once you pass your six month probationary period). 403b. Possibility of interaction with some brilliant researchers.
Kontras
Terrible management and no consequences for bad decisions. It used to be more of a collegial friendly atmospher but in the last few years I've noticed more of a corporate type of outlook. Faculty are encouraged (that's an understatement) to bring in research dollars. Concern over teaching is not as important. On the administrative side I've noticed incredibly mediocre people getting hired into staff positions of power and helplessly watched as they hire their friends to come on board. Cronyism is huge here. In order to bypass unions if they want to remove "problem" employees, positions will be eliminated and then a few weeks later a re-worded job title will emerge.
