Many things are not allowed tI be delivered in the USPS but go through our hands every day. Amazon doesn't really care what our rules are they just send it anyway. For example i had a leaking parcel and my PM said to bag it and delivered it, I said no, I'll leave a notice. That customer happened to have another parcel that day and told me,"I had a leaking parcel? I hope you didn't get any of that on your hands, it was concentrated pesticide". It is illegal for pesticide to be shipped, but there is no method to correct Amazon for doing so. Many of Amazon's employees can't read English and wouldn't even know what the lables say anyway. With that knowledge, I now force only my manager to touch any leaking parcel while she cleans up any spill from any parcel in our office, and reporting to every employee that could have touched it or it's contents, what was inside and leaking.
