This is how a president circumvents the Civil Service rules

First, purge civil servants you consider "disloyal" by reassigning them (often across the country), putting them in duties they're overqualified for or not qualified for, or just firing them.

This overloads the "Merit Systems Protection Board, but the board currently has just one member and is unable to hear cases until more are confirmed. As of the end of 2017, the board had the longest backlog of cases in its history, topping more than 750. Two men nominated by President Trump to serve on the board are currently awaiting Senate confirmation."

Then change the law so that civil servants-- always protected from political retaliation-- are "at-will" employees who can be fired "at will".
"The Promote Accountability and Government Efficiency (PAGE) Act would classify all new federal hires as “at-will” employees, meaning they could be “removed or suspended, without notice or right to appeal, from service by the head of the agency at which such employee is employed for good cause, bad cause or no cause at all.”

Trump is so incredibly incompetent at governing, but boy, he sure can figure out ways to screw the country.
