Legal analysis: According to the law, when establishing labor relations with employees, the company must sign a written labor contract within one month from the date of employment, otherwise it will bear legal responsibility. Therefore, in order to sign a labor contract on their own initiative, some companies will verbally agree on the contents of the contract with employees, and then take a blank contract for employees to sign, that is, a blank labor contract, so we must pay attention to whether it has legal effect.

Legal basis: People's Republic of China (PRC) Labor Contract Law.

Article 3 The conclusion of a labor contract shall follow the principles of legality, fairness, equality, voluntariness, consensus through consultation, honesty and credibility. The labor contract concluded according to law is binding, and the employer and the employee shall perform the obligations stipulated in the labor contract.

Article 10 To establish labor relations, a written labor contract shall be concluded. If a labor relationship has been established and a written labor contract has not been concluded at the same time, a written labor contract shall be concluded within one month from the date of employment. If the employer and the employee conclude a labor contract before employment, the labor relationship shall be established from the date of employment.

Article 36 The employing unit and the employee may terminate the labor contract through consultation.
