When this "job" is replaced by robots, everyone will be better for it. Of course, these people will need to be provided for, and there are several solutions to discuss, but this job screams for automation.
I have no idea what the people in the warehouse do, so forgive my ignorance, but wouldn't this be a prime spot to test out drones? I'm guessing if you are in an enclosed area, the air-space rules that Amazon keeps fighting don't apply?
* It also required 2-3 just out of high-school "technicians" making about $15/hour who oversaw the whole operation as well as a "maintenance" crew of about 3 people (to repair machines). I think there were a couple of managers thrown in as well. Still, much cheaper than the 100 employees we replaced and I am pretty sure those employees were happier doing something else.
