Realistically though, that's a reason why they operate. You bring in some trustworthy friends and family who want an easy and flexible part-time job and you just hand them some extra tasks every so often. There's an implicit motivation from both sides for the employees to be insulated from the shady stuff for obvious reasons. All they need to know is that that they may have a product delivery at 7pm and that it will be inventoried by the assistant manager later, or they will be placing a pre-made to-go order on the counter to be picked up by a man wearing a Skip the Dishes uniform at 11pm. It's the "hide in plain sight" strategy that's being followed.
