Postal Support Employees (PSE) hold temporary appointments for periods not-to-exceed 360 days. Subsequent appointments after a 5 day break in service may be offered but are not guaranteed and should not be expected because the use of PSE’s is discretionary and subject to business needs.
PSEs can be scheduled any hours and the position is intended to be very flexible, including weekends and holidays as needed. PSEs must be available to work when needed.
