The company signed a labor contract but didn't buy social security.

If the laborer fails to purchase social security after signing the labor contract, he may negotiate with the employer to pay it; If negotiation fails, report to the social insurance fee collection agency, and the social insurance fee collection agency shall order it to pay or make up within a time limit; Or apply to a labor arbitration institution for arbitration; If you are not satisfied with the arbitration award, you can bring a lawsuit to the people's court.

According to the provisions of the Social Insurance Law, no matter whether the employer and the employee sign a written labor contract, as long as there is a labor relationship between them, they must pay social security according to the regulations. The employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for its employees. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay.

Social insurance is compulsory insurance required by the state. The state develops social insurance undertakings, establishes a social insurance system and sets up a social insurance fund, so that workers can get help and enjoy insurance benefits in cases of old age, illness, work injury, unemployment and maternity. China's "Labor Law" and "Social Insurance Law" clearly stipulate that it is the legal obligation of the employer to pay social insurance for workers, which is obviously compulsory by the state, and the employer shall not refuse to undertake this legal obligation under any excuse or reason.

Administrative penalties imposed by social security institutions on employers;

(1) The social security agency has the right to directly impose a fine on the employer and the person in charge who have not registered for social security.

(2) Social security agencies have the right to directly impose a fine on employers who fail to pay social insurance premiums in full and on time. If the employer fails to pay or repay the social insurance premium within the time limit, the social insurance premium collection agency may inquire about its deposit accounts in banks and other financial institutions, and may apply to the relevant administrative departments at or above the county level for a decision to allocate social insurance premiums.
