How does China Telecom recruit workers from Class C to Class B?

It is generally impossible to directly transfer from class C workers to class B workers.

Class AB employees are all regular telecom employees, while Class C employees are expatriates. The labor contract signed by Class C employees is signed with a labor dispatch company, not a telecom company. Signing contracts with outsourcing companies has nothing to do with telecommunications companies.

Brief introduction of ABC staff of China Telecom:

Class A workers refer to the formal employees who worked in mobile companies before 2003. Most of them are old telecom workers when the original telecom was split, including provincial companies.

Class B workers refer to employees recruited by provincial companies since 2003, that is, from 2004. They enjoy the same treatment as Class A workers. After one year's temporary rank, there are 6 ranks for undergraduates and 7 ranks for postgraduates.

Class C workers refer to supernumerary personnel recruited by local and municipal branches with the approval of provincial companies according to business needs, and sign labor dispatch contracts with third parties. Network maintenance education generally requires more than two books, and sales personnel generally require junior college or above.
