pointing to just the unions is missing the big picture. I'm sure unions would be willing to adapt and adjust to the on going changes in order to remain competitive. Don't forget the main reason why unions were started (to protect the worker).
If you don't like unions please observe the state of TX and how they do things. The main thing is that USPS is a dinosaur as is UPS. They seem to hate change and are acting like Blackberry when the CEO stated that he never even knew what an iphone was let alone ever used one.
It's obvious they're living in their own bubble feeling nice and protected by the US Government. That bubble is about to burst from their stubborn ignorance and not even the US Gov will be able to bail them out. What ever is coming to them is much deserved.
