I can't quite understand the argument that states the TA is a dog, yet a Yes vote is called for because: 1. Terrorists may strike again. Pretty low odds on that. 2. FEDEX may get a lower offer. Seems they already are beating us in certain areas under their old offer. 3. Another year of Union strife. How would this be any different?
The TA could be fine tuned in a few areas and made much better, why not give that a chance. The downside is purely in the longer wait.

If there is a big downturn in business they will reopen and negotiate down before you can say "Bob's your Uncle".

As it stands we are waiting another six years to be where we should be now, if you discount the paltry retirement.
