To be clear, the pre-funding obligation doesn't mean USPS must gradually fund the pension obligations for an employee as that employee works for them, as would be common in private enterprise. Instead the USPS is basically required to set aside the entire pension obligation, at the date of hire. No one else has to set aside millions of dollars the same day they hire someone.
