Personnel agents are not regular workers, but employees who are not in the company. The length of time depends on the needs of the company, but the salary is basically the same as that of a regular worker.

Personnel agency is similar to talent leasing.

It's the organization that signed the employment contract with you. The salary is paid to you by the agency. You are an employee of an organization. Not the employees of the company they serve.

All the benefits of the employees of the company you provide services are not yours.
