Pros
The benefits package (for administrative/supervisory employees) is well above-average. Vacation for clerical employees is notably less, but with the same medical/health/insurance benefits. Although most competent staff work longer hours, the required hours are few.
Cons
For every hard-working staff member, there is an incompetent one to 'balance out' their efforts. The 'good old boy network,' as at other large organizations, dictates who gets the best positions - competence and ability are seemingly opposing factors. Incompetent staff are nearly impossible to fire, requiring multi-year efforts to document a case while the offending staff continue to wreak havoc. (In one case, an embezzler was demoted - but given a full year under her old salary as time to adjust.) If you can align yourselves with hard-working staff (and even have that luxury - some groups do not), you may be able to insulate yourself from the incompetence around you. However, low tolerance for internal politics or useless staff remaining on the payroll - seemingly paid to drink coffee, chat on their phones all day, and tinker with personal projects - will quickly frustrate you.
