Typically, there are limitations on the number of temporary political appointees that a new Administration can hire. There are exceptions, which are intended to be limited. Under this guidance, the Office of Personnel Management (OPM) has exploited the exceptions to allow agencies to hire an unlimited number of temporary political staffers (known as "Schedule C" positions) who can work for 120 days, with the agency able to extend for another 120 days. The guidance also allows agencies to fill up to 25% of positions at the "Senior Executive Service" (SES) level with temporary noncareer appointments not to exceed 30 days. In other words, the Administration claims it can leverage previously narrow exceptions to bring unlimited numbers of temporary political appointees into the highest levels of government.
