The President issued a memorandum to the Director of the Office of Personnel Management (OPM), giving OPM the authority to make final decisions about the suitability of employees in the executive branch based on their behavior after being hired. The Director of OPM is tasked with creating new rules to support this authority and must consider requiring agencies to report to OPM when an employee's conduct is in question. The memorandum also directs that if OPM decides an employee should be separated or corrected, the agency must take action within five days. This directive is to be followed according to the law and the availability of funds and does not create enforceable rights for individuals against the U.S. government.
Simple Explanation
The President told a government office that they can decide if government workers should keep their jobs based on how they behave after being hired. If they say someone should be corrected or fired, it needs to happen quickly, but this doesn't mean workers can take the government to court if they're unhappy.
