As I understand it, this is saying that warehouse workers (i.e. the people who do physical labor like moving products from point A to point B, or pack shipments) can't help to develop similar systems for their competitors using what they know about Amazon's practices. This does not seem to stop them from doing manual labor elsewhere.
This doesn't seem all that concerning to me. AFAIK this is the exact kind of thing non-competes are intended for. Perhaps 18 months is a little long. I'd guess 6-12 months is more reasonable.
But other than that, this doesn't seem all that bad.
That was my reading too -- they aren't trying to prevent an Amazon warehouse worker from working in a Walmart stock room (even though Walmart and Amazon may be selling the same consumer goods), but are trying to prevent a warehouse worker becoming a Google consultant to help design Google's warehouse operations.
Sounds like there's some overlap with an NDA but Amazon is probably trying to cover all of their bases to give themselves more ammo in a lawsuit.
This was modded as a troll? Really?
