What gets me, is that they had to see this coming. It's not like it was a huge shock that people would be shipping more gifts then ever before. You tell people to stay home, they have to ship stuff to give presents. To me ,that is a lack of planning. And you knew there would be potential for COVID issues. Why wouldn't you staff up and have "on call" staff that you could have trained up before hand and then had them as a reserve team when the current team had to quarantine. Just seems like the whole situation could not be as bad if there was some proper preparation done.
For work we send out Fed Ex packages every day. So far we have not had any delays in the packages we send out. My BIL works for UPS in California and he said they are working around the clock to get packages out and they have even went and rented any trucks, vans, wagons, etc they could find. But they are getting it done with few delays.
