When the campus recruitment signed a tripartite employment agreement, when will the labor relationship be established?

Tripartite Agreement is the abbreviation of the National Employment Agreement for Graduates of Colleges and Universities, and it is a written form to clarify the rights and obligations of the three parties in the employment of graduates. Tripartite agreement is different from labor contract, and it does not mean the establishment of labor relations. Articles 7 and 1 of the Labor Contract Law stipulate that an employer shall establish a labor relationship with a laborer from the date of employment, and a written labor contract shall be concluded to establish a labor relationship. If the employer and the employee conclude a labor contract before employment, the labor relationship shall be established from the date of self-use. It can be seen that the formation time of labor relations is the day of employment. Although college students, schools and a company have signed an employment agreement, college students have not been employed or trained, and have not engaged in some kind of labor arranged by the company. Therefore, no labor relationship has been established with the company.
