Why doesn't Chengdu Wangwang Food Factory directly recruit people?

Want Want Factory has been recruiting people because it has laid off many employees.

Want Want Factory is a private factory. The boss is stingy, the salary is low and the employees work long hours. They work ten hours a day, and sometimes even work overtime for twelve hours. Workers are very tired and earn little. After deducting the room and board, there is not much left. Many workers resigned, so they had to recruit many new employees to supplement them.
