UPS routinely goes through different "flavors of the month" that they like to ride preloaders and drivers on. Next month they'll move onto something (or someone) else and leave you alone.
Currently at my center its load quality/audits. God in heaven on high help you if you don't have at least a 14 inch clear walk space down the middle of the truck.
we dont scan because we dont have enough scanners. half the time the sups never scan me. most of the time i dont see the sup all day. they disappear into hr land
maybe theyre just wanting to pick on someone
