The contract system of Peking University is not all labor dispatch. Not all contract systems in Peking University are labor dispatch systems, but some contract employees may be classified as labor dispatch relationships. The specific situation may be different due to personal position, employment form and other factors. As one of the top universities in China, Peking University employs various employees, including full-time employees, part-time employees and labor dispatch employees. For labor dispatch workers, a labor dispatch agreement is signed with Peking University through a labor dispatch company, and the labor dispatch company pays wages and social security. Most of the formal employees of Peking University sign employment contracts directly and become full-time or part-time employees of Peking University. It should be noted that the labor dispatch system does not encourage overuse, but only applies to some temporary jobs and jobs in short supply. Once used improperly, violations and illegal acts may occur.
