Is PetroChina West-East Gas Pipeline Company a formal labor contract or a labor dispatch?

It depends on what contract you signed. The employees of the West-East Gas Pipeline are very complicated, including formal contract workers, market-oriented employees, loan employees (that is, the labor dispatch you mentioned) and local employees. . .

The formal contract is mainly signed with the Shanghai headquarters. Marketization means that each management office recruits people by itself (and only signs contracts with the management office), borrowing from other pipeline companies (mainly in the northeast), and the local ones are mainly teachers, chefs and doormen.
