Most of the PM air jobs are 22.3 in my building. Saturdays used to rarely have a FTer working. But they have had trouble getting PTers to work Saturdays the last few years. So we used to have many FTers working Saturdays. In the last year they have gotten more PTers to drive Saturdays, so we aren't using as many FT drivers as before. They still need FTers, because there are some ground pickups from certain retailers which UPS arranged a Saturday ground pickup. They even started to do ground pickups from the UPS stores.
