We are in Tucson now. Using USPS tracking, I will find a status that says that the package has arrived. In fact, it has arrived in Tucson, but apparently Tucson mail is sent to Phoenix to be sorted and then sent back to Tucson to be delivered (or something crazy like that - I learned this at the Post Office, but they weren't very clear about what was going on). So the actual delivery may be days after the online tracking system says delivered. Also, the guy at the Post Office said that if you send something like a birthday card or invitation to a neighbor on your street, it may take days or a week before it is actually delivered depending on the backlog at Phoenix - which is processing the mail for a lot of Arizona towns and cities.
I also have been told that all Colorado Springs mail is routed through Denver to be sorted for delivery. I assume this scheme is being used in many places.
This is supposedly being done to cut costs. Another side effect is a reduction in the number of counter workers at local post offices leading to longer delays sending or picking up mail.
Also, the personnel cuts are done based on how long a person has been with the Post Office (union rule apparently) which means that the person at the counter to "serve" you may be really good at delivery, but not so good at going through all the Post Office gobbledy gook to send mail overseas etc- which helps to back up the lines.
Are any other members here running into these delays?
