I think UPS does a much better job than the competition. I hate most 3PL logistics companies. LaserShip comes to mind.
That said, the Teamsters Union specifically has been putting a ton of money into bad PR for Amazon.
They've directly funded staged protests at AWS Summits in NY the last few years. They are a powerful union with deep pockets and connections.
Also with the economic realities of journalism in this era, many news articles are literally PR pieces written and provided to journalists for publication. Most of this is undisclosed.
I think it's perfectly valid to call out what this article looks like and at least ask questions, as there are folks out there with more resources than I have to follow up on this. It isn't an attack, because I didn't make a statement -- I asked a question.
