Why do mobile companies need a third party to recruit people?

The third-party employees of mobile company are the employees recruited by the third-party labor service company entrusted by the company. Although these employees work in a mobile company, they are not registered employees of the mobile company. The third-party company is responsible for the wages, insurance and benefits of these employees, and these employees are not included in the total number of employees of the mobile company.

It is very different from the salary, reward, subsidy, insurance and welfare of employees in mobile companies.
