Pros
If you are lucky enough that your boss likes you, you can get a really well-paid position. Good benefits.
Cons
The organization has well-formulated policies and other governing documents. The problem is that management does not care a whit about complying with them. They make arbitrary decisions and do not care much about the consequences because they have immunity. Management rules with fear, and instead of leading employees and creating a good workplace, they have created a toxic organization where employees rather than collaborating compete against each other to please their managers, so that they may receive a promotion or salary increase. In reality, there are no objective success criteria for you as an employee. The vast majority of employees experience how their careers slowly but surely wither, in an institution that has long since lost its relevance. This does not prevent the leading minority from putting their foot down on the toil of their subordinates, and living good lives with high incomes, good benefits and diplomatic status. The organization is not led by leaders, but by narcissists. A real re-furnishing of the management is required in order for this organization to be saved, and its employees with it - before they flee to other institutions like rats from a sinking ship!
