evidence: The US Postal Service has been delivering Amazon packages for years, but this month's protest reportedly came in response to local implementation of a new agreement with Amazon at the beginning of November. The Bemidji Pioneer quoted longtime mail carrier Dennis Nelson as saying, "We're being forced to work 12-hour days, six days a week. All of our days off have been canceled by the district manager. They've even gone so far as to say they will not honor sick leave. On top of that, we've been told Amazon is now our priority, that Amazon packages are the most important thing we do, the mail is secondary." [...] When contacted by Ars today, a USPS spokesperson denied that the agency prioritizes Amazon packages. "We do not prioritize Amazon packages. We deliver packages and mail in an integrated network," the spokesperson wrote in an email.
