It's taken 25 pages of explanations and he still isn't getting it, so you're probably right.
As of now what we know is that the company, at least in some areas, seems to agree with
@upschuck's assessment of the situation. No $.70 raise last year, yes $.75 this year. That fact tells us the company does not agree that gwi is cumulative with progression, as
@BigJamesBrown argues it is. If we can find someone who has moved into their 3rd year of progression since August 1st of this year, we can at least verify how the company interprets the language.
Not saying that the company is correct in their interpretation, simply that, so far, they seem to agree with
@upschuck's interpretation. The question still remains, why did they start interpreting it this way this contract?
One possible answer I came up with is that something changed in the language between two contracts ago and the last contract. Anyone who was around then, especially those in progression, will remember that between those two contracts the progression period changed from 3 to 4 years. Those in progression at the start of the last contract got to stay in the 3 year progression, but I don't know if their progression rates changed. If the language that kept them on the progression from the previous contract stayed, the drivers in progression as of the start of the current contract would still be in the progression they were hired under. That's all speculation on my part, I haven't compared the previous two contracts, as I don't have access to the 2009-2013 contract.
