Incredibly political and cutthroat environment at times, FAS especially so compared to other schools
Very gossipy (FAS, I am looking at you) and a rampant rumor mill
If you have a faculty boss, your chance of a positive and fulfilling work life drops dramatically--there are wonderful faculty, I've worked with 7 total, all but 1 had aggravating moments, 3 were fatally terrible (2 of which are why I am leaving!)
Faculty managers are appointed based upon distinguished research or careers outside higher ed, but are often notoriously terrible managers
No connection with performance to reward
Performance reviews are sporadic (good luck convincing your faculty to give you 30 minutes of their time to review you once a year)
Union jobs = often equals a bunch of lazy people coasting with lacking skills (especially the multiple decade veterans) and will hold you back from advancement since taking on more to work your way up is verboten (can't make the former look bad!), will be chained to desk for set hours (less flexible) but will leave on time (they don't like to pay overtime)
Salaried jobs = work/life balance evaporates entirely, will get worked many, many hours
No dependent or spouse educational benefit
Students can be snooty, entitled, rude, and lack common sense (more so than BU which didn't have this issue when I worked there). Lots of student hand-holding.
Senior management will not discipline or replace incompetent faculty in administrative roles--even if you are right, you have to get along with them or leave
