Do they know who is staying and going yet?

I suspect Team 2 is “safer” than Team 1. They have made it clear they don’t want to disrupt the Eliquis contract. That being said…it doesn’t mean they won’t lose jobs but less of them will lose their job. Personally I think Team 1 will all be let go.
My guess is your correct. If they wanted to keep team 1 they would have trained us on Eliquis. The fact that they gave team 2 Cologuard sealed team 1's fate. Team one will have the same fate team 3 had.
