cinkat,
/m21331 In a directive issued by the USPS on 3 March 2004, a change was made in the long-standing and widely accepted practice of permitting X, O, and "Z" days to qualify a carrier for a free Saturday(s). According to the directive, effective pay period 06-04, the following rural DACA codes will not break the continuity for a free Saturday on a J or H route:
Annual Leave, DACA code A
Sick Leave, DACA code S
Donated Leave, DACA code D
Court Leave, DACA code 6 (new code)
Holiday Leave, DACA code H
The use of any other DACA codes during a period of leave will break the continuity of the leave and therefore disqualify the carrier for a free Saturday.
