The federal bureaucracy carries out the day-to-day work of the government as the nation's largest employer, with over 2.7 million employees managing tasks like mail delivery, regulating businesses, collecting taxes, and overseeing national forests. While it provides hierarchical authority, job specialization and formalized rules, the bureaucracy also faces criticisms of being inefficient, wasteful, and overly bureaucratic. The Executive Office of the President oversees executive departments like State, Defense, Justice and others, as well as independent agencies like NASA, Social Security Administration and the Federal Election Commission that operate outside the traditional department structure.
