I have had a decent amount of sales managers but the ones that pretty much earned my respect are the ones that will openly disagree with a BS change in the way things are done.
You know the ones that actually care about your personal financial well being over drinking the company's juice.
One time my old manager hated the highers up so much he told me a story where he had a dream where he pointed a gun to his CEO's kids and told his direct manager that if he doesnt suck off the CEO till he cums his gonna shoot the kids. So the CEO would frantically tell my boss's boss to suck him off.
Obviously he was joking but man whenever there was changes for the worst it was easy for me to bring it up to him. With my current sales manager i really got to watch my wording when i disagree with whatever changes the higher ups have made. How are you guys with your managers?
