1. Business development demand: With the rapid development of the collection platform, the order volume is increasing. In order to meet the increasing demand of users, it is necessary to expand the storage capacity and increase the number of warehouse personnel.

2. Summer worker flow: The goods warehouse may recruit a large number of temporary workers or interns during the summer vacation to meet the work demand during the peak order processing period. However, these summer workers may leave after finishing their work during the summer vacation, resulting in the need to replenish the warehouse.

3. Personnel transfer: The acquired warehouse may adjust the positions of employees for various reasons, such as work needs or personal development of employees, resulting in the need for additional personnel in the warehouse.

4. New employee training: In order to improve the work efficiency and quality of new employees, the acquisition warehouse may conduct training for a period of time after recruiting new employees, which also requires a certain time cost.
