Hey David! I work at PHL4, which a fulfillment center in Pennsylvania. I can agree with you that working in a warehouse is hard work for sure. My FC is huge on safety and has made it their number one priority. I wouldn't work here if I thought Amazon was doing anything unethical or out of the norm. I do have a rate that I find to be very easy to reach and makes the day go by faster.
