I am a letter carrier for 24 years, most people do not understand what we do. 90% of new hires quit after 1 week or donot make there 90 days becouse its alot harder than you think. I used to get mad when people talk down about the post office, they just donot understand. Yes its not perfect but without the usps prices for shipping would sky rocket becouse usps is designed not to make any more money than needed to stay afloat. Where ups and FedEx can charge what ever they want. Another thing if usps were to shut down, everything in the world would stop. We do alot more than walk around and deliver junk mail
