Can Sichuan Airlines' security officer labor dispatch become a full member?

Of course. Article 19 of the Labor Contract Law of People's Republic of China (PRC) stipulates that the probation period of a labor contract of more than three months but less than one year shall not exceed one month, that of a labor contract of more than one year but less than three years shall not exceed two months, and that of a labor contract of more than three years without a fixed term shall not exceed six months. Sichuan Airlines security officer labor dispatch workers can become full members after the probation period, and the labor dispatch unit is their employer.
