Is it possible for the third party to enter the formal establishment when the subordinate units of Western Drilling sign the contract?

the contract signed by the subordinate units of western drilling means that the third party has no chance to enter the formal compilation. Because the establishment and management of the company need to comply with the relevant national and local regulations, requiring recruiters to go through open recruitment, examination, interview and other procedures, qualified personnel can be included in the establishment of the company, so the third-party personnel introduced by the subordinate units of Western Drilling have no chance to enter the formal establishment of the company.
