What if the company doesn't sign a contract or buy social security?

It is illegal for a company not to sign a contract or buy social security.

According to Article 82 of the Labor Contract Law: "If the employer fails to conclude a written labor contract with the employee for more than one month and less than one year from the date of employment, it shall pay the employee twice the monthly salary". Therefore, enterprises should pay double wages when dissolving labor relations. If not, employees can apply for labor arbitration.

The Administrative Regulations on the Declaration and Payment of Social Insurance Premium requires that the employer shall register social insurance for its employees and declare and pay social insurance premiums within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay.

The social insurance premiums mentioned in the regulations refer to the basic old-age insurance premiums, basic medical insurance premiums, work-related injury insurance premiums, unemployment insurance premiums and maternity insurance premiums paid by employers and their employees according to law.

According to the regulations, the employer shall inform the employees themselves of the details of the payment of social insurance premiums on a monthly basis, inform the employees' congress of the unit every year or announce the payment of social insurance premiums in a prominent position in the unit's residence, and accept the supervision of the employees. The details and changes of the payment declared by the employer on behalf of the employee must be signed by the employee himself and kept by the employer for future reference.

In view of the fact that some employers fail to pay social insurance premiums in full and on time, the regulations are clear. The social insurance agency shall order it to pay within a time limit or make up for it, and impose a late payment fee of 0.5‰ on a daily basis from the date of default; If it fails to pay within the time limit, the administrative department of social insurance shall impose a fine of 1 times and less than 3 times.
