Okay I can understand that then never really thought about it but that makes sense.
I guess it depends on what is being manufactured. My hubby works nears a large hot furnace. It is grueling work specially in the summertime. There is no A/C only large fans. He takes the product off the line after it comes out of the hot furnace. He has burned himself many times.
It's alot different then packing boxes of merchandise. I have shopped with Amazon for years and I think of all the stuff I bought only one came in bad shape. A book came with the cover bent because the person wasn't too careful when putting it inside the packing envelope. It was a free book so I didn't complain. It was one of those 3 for 4 Promos they always have.
