Yep. Mine is the opposite of @PT Car Washer's... Everyone on preload gets the dollar, including unloaders. They wouldn't be able to hire enough people otherwise.
ffs.... sorting by SLIC isn't a "skilled" position anymore than sorting by PAL. A rhesus monkey can do either job and all PT new hires should start at $11/ hr if for no other reason than COL.
The building I started in everyone got the extra dollar no mater what you did do to the size of the building you might have gotten moved some where at any point in the shift.
