Promotions are ONLY available to people who have high sales numbers. Fortunately, some of those people happen to be good in other aspects of the business. I saw many better-qualified people get passed up for promotion for people who were not great employees but had a high percentage of sales of the protection products.
Insider definition of a Counter Dodger: an employee who finds ways to avoid working with repeat customers who they know don't buy the insurance, so that the employee can avoid a negative hit to their sales statistic number (which is a number that shows the number of sales made as a percentage of the number of customers an employee had).
No commission for sales, just the carrot of selling well to get you promoted after a couple years.
