The organization of public-sector unions and the emergence of merit employees as a powerful interest group underscores one of the great inherent dilemmas of bureaucratic autonomy. On the one hand, the merit system was created to protect public employees from patronage and the excessive politicization of the bureaucracy. On the other hand, those same protective rules could be used to shield bureaucrats from accountability, making them hard to fire when they failed to perform. Bureaucratic autonomy could lead to high-quality government with public officials looking to the public good. It could also protect bureaucratic self-interest in job security and pay.
