Also agree this isn't how Amazon does it. Humans are still way cheaper than robots in their biz.
For a fascinating and time wasting side trip on the Internet, look up full- time RVing blogs and "workampers".
A large percentage of folks who've "retired" to traveling in RVs work for Amazon at various locations every Sept-Dec. They get free RV parking and hookups and paid to do the mass manual labor Amazon needs for the holiday season.
OT is mandatory after about November and they all blog similarly... At work by 5:55A to clock in at 6, back to the RV bed hopefully by 9P, a handful of strictly controlled breaks throughout the day, and sore from hard physical work.
Those who do it, seem to appreciate the cash stash they build in three months that covers most of their expenses for a year. It's quite popular actually.
