Preventing a Patronage System Act or the PPSA Act This bill prohibits executive agency positions in the competitive service from being placed in the excepted service, unless such positions are placed in Schedules A through E as in effect on September 30, 2020. The bill also prohibits positions in the excepted service from being placed in any schedule other than the aforementioned schedules. On October 21, 2020, the President issued an executive order titled Creating Schedule F in the Excepted Service. The order places executive agency positions that are of a confidential, policy-determining, policy-making, or policy-advocating character, and that are not normally subject to change as a result of a presidential transition, under a new schedule in the excepted service (Schedule F) instead of the competitive service. The order also requires any such positions in the excepted service to be reclassified to Schedule F.
