2, the contract signed by the construction company and the project department;
3. The project department or the construction company signs a labor export contract with the labor export company (basically a mere formality, with no practical effect, for the purpose of handling building construction permits to meet the needs of building regulations, the labor service company just tries to collect some fees);
4. The project department subcontracts labor services to private contractors and signs contracts (such contracts are basically invalid,); The contractor will not sign labor contracts with migrant workers, which is the fundamental reason why the legitimate rights and interests of migrant workers are not protected;
However, the administrative department is generally edging the ball. For example, when a building construction permit is issued, the construction unit only needs to issue a labor export contract; The payment of migrant workers' wage deposit appears in the form of guarantee.
Of course, large construction companies are relatively formal, but the social endowment insurance, unemployment insurance, medical insurance and housing accumulation fund of migrant workers have not been realized, which is their construction profit.
