What courses in RT Mart have the highest salary? Please be more specific

Although the level of the person in charge of the shopping guide is higher than that of the department assistant, in the human resources department, the person in charge of the training department is ahead of the person in charge of the shopping guide, and RT Mart pays more attention to the level. Under normal circumstances, the head of the training department will not be promoted, and the head of the shopping guide will not develop. Although the level of department assistant is low, it depends on the department. If it is the general assistant of the store, it is also the assistant level, and there is a lot of room for development.
