The RST sales division is hemorrhaging sales reps. Because of decreases in bonuses, mandatory use of EV's, pathetic lunch money and an anemic number of samples, a demoralized sales force will be looking for other jobs. So when layoffs come in the near future, AZ will not have to pay a severance package to as many reps.
Also, teamwork between RST reps will probably decrease, since there's responsibility for only 1 drug.
I am sure there's a chess game that's being played by upper management at AZ, and sales representatives are not part of that game.
