(Nationwide) - It's three days after Christmas and many people are still watching their mailboxes waiting for presents to arrive. 

The US Postal Service has experienced historic delivery challenges this Christmas season.  The pandemic has prompted more people than ever to both shop from home and deliver presents through the mail.  At the same time, more workers than ever, namely federal postal employees, have been calling off sick.  That means fewer people in post offices to process all the packages, which have been piling up in distribution centers and on mail trucks.

And it's not just the government that's caught up in this perfect storm.  FedEx and UPS have reported similiar shipping delays.
