Cliff, have your steward request info on the bar codes. It will show receive time, "no access", then delivery by you on Monday. This is work left for you from Sunday, that means you didn't receive your compete relief day, and are owed for the work left for you.
Lost, UPS doesn't plan on leaving us anymore parcels. They are smart, so soon they will place a sur-charge on all their parcels for the "Christmas " period, which starts at Thanksgiving. That move will give the funds UPS wants with fewer parcels to carry/ handle. By the way that means we "USPS suckers" will be delivering all of those parcels for the same low, low, low price. Kinda sound's like the used car salesmen that the USPS upper managers are.
You can use the USPS app to look up those bar codes.
