No, if a Contract proposal isn't ratified, it does NOT mean that the next step is a strike. It means that both sides go back to the negotiating table and hammer out a deal. UPS has made it pretty apparent that they'll be fine with you guys joining the Teamsters so I don't see a major problem getting a Contract. UPS knows about what to expect in a UPSF Contract and isn't worried about it...if they were they'd never have agreed to the card check.
Allow me to explain something here.....Maybe you guys have been led to believe that the Teamsters like to call strikes. Nothing could be further from the truth, and that's evident since we, in freight, haven't had a general strike in over 12 years, and probably will never have one again. Both sides know that a strike these days would devastate(Sp?) the remaining Carriers financially and if they closed we'd all be out of jobs. This isn't the 60's or 70's guys. The top dogs on both sides know this and work together to meet in the middle. And here's a real novel thought.....most of today's Teamsters even realize that we need to be more flexible to compete in an atmosphere where our competition has very lax work rules or none at all. Somebody posted ABF's numbers yesterday....they operated at 90.1....and they're Teamsters.
UPS bought you guys for a reason, and now they're paving the way for you to join the Teamsters. Do you really think that when you join that they intend to be so hard-nosed at the negotiating table that you're forced to strike? Use some logic here guys....just relax, it'll take some time, but things will be ok. Be patient, you'll see.
