Really no one more guilty than others. Notice how nothing is in writing on what people did, officially being let go. I stand by every territory was/is a misrepresentation. Did the managers know? Yes. For a fact they did, not just arbo though. Allocations were flawed for tens if not hundreds of thousands of dollars per territory. Reps knew it, managers knew it. Is that and better than emails? How about all of the run away accounts managers told the reps to keep? That was for way more money than any email. Allergan was flexing their corporate muscle hedging on people being weak, and going away when they cut reps and didn't pay managers. When they hit individual arbitration on this matter they will lose. It's just a matter if people will see it through. I challenge anyone to find a policy that outlines why they did what they did. They don't have anything.
I know of specific examples across the country that managers knew about, EVERY MANAGER. No one is as clean as they think they are. We can lie to ourselves, that's one thing. But if you truly feel better than anyone that was let go, you're either in denial, or just not that bright.
Keep cashing that check every two weeks until it's your time.
