Apparently DHL directed their sales staff to notify all US customers that they would have 90 days to find a new shipping company.
Then DHL canned the sales staff after they delivered the news to their clients.
Looks to me like DHL USA will not be around in the current form by December. Just a wag but I bet DHL will contract out air and ground to UPS. I also see the USPS delivering some DHL ground shipments too. They will not close up shop in America because they are a global company. You will still be able to ship to the USA via DHL, but it will be outsourced to UPS.
That's my read on it.
