You summed up things SUPERBLY here! Without knowing who you are, I think I'm correct when I say that you were hired during a time when this industry was classy. The manner in which you write here tells me that you were uniquely qualified to be hired into this industry. You exhibit qualities of which those individuals who were hired over the past 5-6 years can't fathom!
And you hit the nail on the head with your mention above of the "brilliant managers who over the past 2-3 years found a way to force the true, talented honest reps with integrity out of this company."
A clear example is the manager (East Coast/MD/DC area), who cleverly "exited" all of the legacy reps out of the company within a 2-3 year period. This is the caliber of manager the company keeps on board. This individual brought No true management experience to the table and inherited a high performing team, top performers from other companies who were recruited to come here -part of the ORIGINAL 135 hires! - a Team any manager could only DREAM of having. One by one the team was dismantled. The truth of the matter is that there was nothing this manager could offer these individuals (as most of them had several years more in the industry than the manager). It's as if the team needed to be gone so the manager could appear to be superior!
