按照《中华人民共和国劳动合同法》(以下称劳动合同法)规定,劳动合同的订立时间存在三种状态:一是在建立劳动关系之前订立,二是在建立劳动关系之时订立,三是在建立劳动关系之后订立。关于劳动合同的生效时间,法律没有对以上三种情形进行区分,而是作了统一规定。 In accordance with the “Labor Contract Law of the People's Republic of China” (hereinafter referred to as the Labor Contract Law), there are three states for the conclusion of a labor contract: one is done before the establishment of the labor relationship, the other is made at the time of establishing the labor relationship, After the establishment of labor relations entered into. On the effective date of the labor contract, the law does not distinguish between the above three situations, but made a unified provision.
