Why does KFC keep recruiting reserve managers?

Let me answer your question, maybe I am the standard answer:

Reserve managers have been recruiting for three reasons. First, KFC really needs more talents to train more store managers and open more branches to develop itself. Second, when a reserve manager comes in, he needs to learn a lot in his post. From the actual operation of the employee to the dribs and drabs of management learning, it can also be understood that he is a super employee, that is, he does everything, because the reserve is the future store manager and must know everything. Third, as you said, there is a lot of liquidity. Why is there great mobility? Many people can't help it, because the learning process is very hard and the work is very tired. In addition, once I can't get over it, I feel tired and can't make much, so I leave my job, so I have been recruiting for this position.
