It's not uncommon for some agency leaders to be replaced - particularly those dealing with policy-oriented matters, like say the FTC. But that doesn't apply to the rank-and-file because of various civil service reforms which are designed to provide continuity between administrations and avoid partisan flip-flopping of large numbers of employees. They were also designed to avoid corruption or the "selling" of government positions to those favored by the president, which was common back in the 1800s. Trump is taking us back towards greater corruption while disguising his acts in a cloak of "rooting out corruption".
