Very much so. Early on in our Prime experience about 2 years ago one of the delivery men, after dropping off the package, went back to the van, whipped it out and started peeing in the street. All while our neighbors kids were playing in the front yard. I thought twitter would be a good place to contact Amazon's support, and they didn't seem to care. That guy never delivered again, but no real response to my concerns was a bit creepy to say the least.

Otherwise packages come from all makes and models of cars over the last 6 months. Still pretty cool to get most things same day delivery cheaper than me driving to Fry's for a piece of hardware. I don't see how they make money though and compete in the long run after VC runs out.

USPS pays fairly well, I thought. Don't know much about working conditions though.

Yea, they're not know for their wages or working conditions, unless you're in IT ... or a robot.
