There will not be a need for a second pass if the numbers are not met. The offer protects the company from litigation. If the number is not met they can come in, give you a severance package and tell you your job is eliminated. You say "this is not fair, I'll sue". Company says, "we made you an offer and you turned it down". The risk were stated upfront in the package that you ran the risk of not having a position and it is "strongly encouraged" that you consider the packet if you got one.
This gives the company all the flexiblity it needs in case enough packages are not taken.
It won't make it down to the supevisor level because this is where the "meat and potatoes" of doing business on a day to day basis is done. They know too many in this group would probably take it and this puts the company at a far greater risk than grade 18"s leaving who are doing duplicate jobs.
It's all right there in the "Q and A".
They took the power to select the new grade 18"s out of the new district manager's hands. He has the new structure, but not the team. Teams were put together by the region based on performance scores, education, years of experience and the other critieria listed in the Q and A. In a nutshell, they are looking for young grade 18's (in my opinion) who can run two or three divisions and are young enough to be around for a couple of years and oh yeah who will do it for less because they don't have the big salaries and stock options of the current 30+ year guy. Just saying......
