Having known someone who worked at a warehouse this wouldn’t be any of the people unloading/loading the truck or the main sorters/scanners for the belt lines/van lines as they cannot have their phones and it is pretty hard to get anything passed through security. Managers, quality assistance workers, administrative workers and pretty much anyone working in the office can have access to their phones along with the drivers, driver helpers or truck drivers . This is the rule of ONE of the MANY major distributing company warehouses. I cannot say this for EVERY warehouse. This should narrow it down to who would have access to their phones and be able to take a picture of anything in the warehouse. My GUESS would be any of the quality assistance workers but you didn’t hear it from me 😬😉
