I have observed several hundred salespeople who were taught to use deceptive practices like 'bait and switch' and encouraged to play negotiation games with customers. They were so stressed by this behavior that they suffered from a high incidence of alcohol and substance abuse, divorce, job-jumping, and low productivity. In the same industry, I have observed countless people who had been taught to sell with high integrity. Ironically, their customer satisfaction, profit margins, and salesperson retention were significantly higher.
