The holiday season came and went, and it appears the U.S. Postal Service did a good job. Yes, there were some reports of letter carriers getting swamped with packages here and there. And, yes, there were citizen complaints about delivery delays and mail theft. But on the whole, the USPS delivered in late 2023. There was no systemic crack-up as there was in December of 2020, when bad weather, sick mail workers and other factors slowed holiday cards and gifts for days and even weeks.
