Is it legal to sign a contract repeatedly? Is it illegal to duplicate contracts?

It's hard to say it's not legal.

In 2008, the employer signed a five-year labor contract with you, and as of January 1, 2010, you were still working in the employer It is an indisputable fact that you have had an employment relationship with the employer during these two years, and this will not be erased by the re-signing of the labor contract. At present, in addition to signing the contract, the labor and social security department also goes through the procedures for paying social insurance, and the unit should pay the annual insurance premiums for you, and the social security department will have written procedures for you to pay the insurance premiums. If you do not agree to accept the terms of the new contract, you can submit comments to the unit, because you say that the unit re-signed the contract in order to pay the insurance premium, then you can request the unit to extend the contract period of the new contract to the original five-year deadline.

If you don't mention it, after five years, when a lawsuit starts and you sign a new contract, then the employer may raise your objection if you don't raise an objection at that time, indicating that you have agreed to change the terms of the new contract.

It is not impossible for the employer to re-sign the contract, but it should be signed on the basis of the original contract, and unless you have no opinion on the terms of the new contract, you should raise your objection.

The employer may enter into a supplementary agreement on the re-application of insurance under the condition that the term and content of the original labor contract remain unchanged, and the term of the re-signed contract will be shortened, which is not conducive to the interests of the employee, and the employer shall not unilaterally change the term and content of the labor contract without the consultation and consent of both parties.
