You miss the point. They worked as a team. They failed as a team. Time for a new team.
It doesn't really work that way in the banking world. Each group is its own profit center. If the bond traders do well but the equity traders do not, the equity traders don't get a piece of the bond trader pot.
So, if I was a banker in profitable division who was seeing my salary capped due to the failure of other divisions, I'd be threatening to jump ship too.
