I have a problem believing that article for a number of reasons. One of my best friends works for UPS and has for going on 20yrs. The las time they striked which was back in the 90's, when they signed the new agreement, part of it was so they couldnt strike again for 20yrs, and it hasnt been 20yrs... Also UPS payed several BILLION's of dollar and bought out all of their employess from the Teamsters, that happened fairly recently. I'll talk to him tonight and tell him about that article and see if there is any truth to it.
Me personally, I could careless either way, I use fedex.
