You must be joking. Do you work in Human Resources? Do you have any idea how much advance-planning and effort goes into a restructuring like this?
Do you really believe that, after the fact, a random rep asking his A.B.L. for a severance package will compel the entire organization to change their minds on voluntary seperations?
What do you think your A.B.L. will think of you if you do this? Maybe that you are an ignorant clown who has no idea how multi-billion dollar corporations work? And you hate your job and will likely quit inside of a year?
This is one of the most insane things I have ever read on this site, and that covers an awful lot of ground.
If you are that desperate to stay with Novartis, why don't you check the job-postings? Between the placed reps shifting territories and organic vacancies you should have no trouble finding a landing spot if you are willing to relocate.
Also, what you said is completely incorrect. There is extreme harm in asking (your A.B.L. will be looking for your backfill that day) and absolutely nobody would understand (again, you have confirmed that you are looking elsewhere and they will manage you out as quickly as possible).
Follow this preposterous advice at your own peril.
