In order to protect the rights and interests of workers, there are some legal documents of labor-related laws to protect the rights and interests of workers. According to this document, employers and employees will sign labor contracts in accordance with the principles of fairness, equality and legality. Then some people will wonder whether the labor contract has not been provided to the staff. In fact, it is illegal to sign a labor contract with both parties or not to hold a copy, which violates the relevant provisions of the labor law and cannot fully protect the interests of workers. First, a labor contract is an agreement between an employer (including enterprises, institutions, state organs, social organizations and other organizations) and workers to determine labor relations and clarify mutual rights and obligations. The specific content is: 1. The main body of a labor contract consists of a specific employer and a worker. One party to a labor contract is an employer such as an enterprise, institution, organ or organization, and the other party is the laborer himself. 2. Both parties to a labor contract must have the qualification of contract subject. Employers should have legal personality, and private enterprises should mainly have citizenship; Laborers must have the ability to work and the right to work. Workers must be at least 16 years old, be in good health, have a junior high school education or above, and perform well in reality. 3, state-owned enterprises to recruit workers, must be in the national labor employment plan indicators, and to the local labor department for employment procedures. 4. The draft labor contract is generally put forward by the employer to solicit the opinions of the hired workers; It can also be directly negotiated by the recruiter and the administrative representative of the enterprise, such as the factory director, manager, personnel department and section chief. 5. Before signing the labor contract, the employing unit shall truthfully introduce the situation of the unit to the recruited person, and the recruited person also has the right to put forward his own opinions and requirements. After full consultation, both parties shall fill in the labor contract with brush or pen, and sign and seal it. 6. After signing the labor contract, it shall apply to the local labor administrative organ for verification, and file with the competent department and the local labor department. The above six points are the specific contents of the labor contract. Then the answer to the question that the labor contract does not mention the supply of personnel is definitely wrong. According to the provisions of the Labor Law, a labor contract is a voluntary contract signed by both workers in accordance with the principles of fairness and justice and in compliance with legal provisions, which is used to protect the rights and interests of both parties. After affixing the corresponding seal, the employer and the employee each hold one copy. Without the consent of both parties, the contents of the contract shall not be changed at will, and the term of the contract shall not be terminated at will.
