Pros

Friendly fellow workers depending on the departments.

Cons

Some of the departments are extremely toxic with useless management. Politics, favoritism, way too much work with no extra help, management is yelling too much at a certain group without a reason while allowing the toxic workers harassing/intimidating and even be hostile to the point threatening with physical violence is involved instead of actually doing something about it.
