They use real "live" packages for Salts, and sometimes fake ones. The Salt can "show up" in your truck at any point during the day...while in a resturaunt etc., any time, even after you return to the bldg! Here is a link and a quote from a case where
a driver was fired and subsequently won a $6,000,000 lawsuit against UPS (later appealed, final disposition unknown). Text in
anything unusual and ask for guidance.

"To prove his claim that UPS terminated him under false pretenses, as part of its plan to target “injury repeaters”, plaintiff presented the deposition testimony of a former UPS supervisor, Guy Findeisen. Findeisen testified that he had worked at a UPS center in Hialeah as a driver and supervisor until he left in 1987. He said that when he was there, his supervisor, Bill Hughes, taught him a way to set up an undesirable employee for termination through a “presheet audit,” and that that he had personally “built the case” for truckers to be terminated through a fraudulent presheet audit. Findeisen explained how he would remove a package from the driver's truck after it had already been loaded and then falsify the records to make it appear that the driver had not bothered to deliver it. He testified as follows:
How the presheet audit, how the fabrication went. I go into your truck, I pick out five, six areas. Again, this time the package, one of the small packages, ABC, make sure it has a sequence number on it. I would hide it in my drawer. When the driver came back that night, I would say look Juan or whatever, you have a presheet audit, here are the numbers I'm looking for, I'll be back in minute ․ go back in the truck, take the package and throw it back in again ․ He's definitely going to come up one short because it was not in the truck, so when that happened, it became an integrity problem.
Findeisen testified that he did this about five times and that he knew of at least two employees who were discharged as a result. He said he also knew other supervisors at his facility who had set up drivers in this same way, and that it was an “unwritten rule at UPS” and “an easy way to get rid of somebody.” Findeisen testified that when he heard about the plaintiff's termination, he recognized that it was the exact same method he used to terminate employees.
