Pros

Large organisation helping people in need. You feel like you are actually helping people.

Cons

Toxic culture, people are allowed to play favourites. Tenure is more important than work ethic, ability or skill. Support from HR and from upper management is incredibly weak. The only way to survive is to play the political game or be burnt out from too much work.
