劳动合同对劳动关系起到了一个有效的规范作用,是用人单位、劳动者规范双方当事人在劳动过程中发生的社会关系契约,对规范劳动关系起到了积极的作用。由于劳动合同关系的复杂性,因此,在劳动合同签订后,劳动合同是否有效,直接关系到双方的利益,企业的发展,社会的稳定。 Labor contracts play an effective normative role in labor relations. They are the employer units and the workers who regulate the social contract that both parties have in the labor process and play an active role in standardizing labor relations. Due to the complexity of the labor contract relationship, whether the labor contract is effective after the labor contract is signed has a direct bearing on the interests of both parties, the development of the enterprise and the social stability.
