I had a purchase from Amazon sent to me using FedEx/USPS. I don't blame FedEx or USPS or even Amazon. All I know is that I'd probably have had the package delivered in 3/5 by FedEx. And maybe the same from the USPS but when they both were involved it took 11 days. This unholy union may be worth $10.5 billion dollars to someone but not to the customer.
Btw, I don't believe unions are a cancer or have outlived their purpose or rob from businesses. If anything it's the reverse and they're needed now more than ever.
