Dan, Costco also promotes from within. Somebody mention that their tire guy was now fitting hearing aids. That’s likely true. Costco promotes people to better positions based on longevity and employee rating. Some don’t want the management route and this is a way to make better money and rewards them.
The clerk in the department is the person who would get such a promotion and the tire guy above was that too. The one at my store is now doing that. They said it is about 5-6 modules a week and takes 9 months. Costco is paying for the course.
