During the employment confirmation period, the company will evaluate employees' work performance, work attitude and work results. If the employee performs well during the period of becoming a regular employee and reaches the standard of becoming a regular employee stipulated by the company, he will become a regular employee. On the contrary, if an employee's performance is poor and he can't meet the company's requirements for becoming a regular employee, then he may not be able to become a regular employee.
Therefore, it is best to consult the human resources department or leader of the unit to understand the specific policies and regulations of the enterprise.
