Is it possible for postal courier recruiters to become full-time employees?

I suggest you communicate with the personnel department of the postal service. Generally, many state-owned enterprises are engaged in labor dispatch contract workers and are unwilling to recruit regular employees. As far as I know, the business personnel recruited by Postal Express and Postal Savings Bank are all labor dispatch contract workers. People who choose to work in the postal service want to review the civil service exam in a relaxed working environment, so the postal service basically recruits people every year.
