A small jeans factory has about 100 people. A few clerks are usually invited. How to divide the work?

Under normal circumstances, there should be about six clerks, one of whom is the head of the personnel department, and the other is under the personnel department, mainly responsible for the recruitment, training, promotion and demotion of personnel. The other executive is the administrative staff, who is mainly responsible for the company's logistics services and guarantees, such as employee welfare, employee attendance, employee dormitory allocation management, etc. In addition, the company needs at least two financial accountants.
