When employing workers and establishing labor relations, employers must sign labor contracts and pay social insurance according to law. The probation period is within the labor contract, and it is by no means to sign the labor contract after the probation period expires. Therefore, paying social insurance must be paid when employees join the company. If the unit and the employee have established labor relations for more than one month without signing a labor contract, they must pay double wages from the second month. The legal basis is as follows:

Article 72 The sources of social insurance funds shall be determined according to the types of insurance, and social pooling shall be gradually implemented. Employers and workers must participate in social insurance and pay social insurance premiums according to law.

Article 73 of the Labor Law: Laborers shall enjoy social insurance benefits according to law under the following circumstances: "Five insurances"

(1) Retirement;

(2) getting sick;

(3) Being disabled at work or suffering from occupational diseases;

(4) unemployment;

(5) bearing.

After the death of an employee, his survivors shall enjoy the survivors' allowance according to law.

The conditions and standards for workers to enjoy social insurance benefits shall be stipulated by laws and regulations.

Social insurance premiums enjoyed by workers must be paid in full and on time.

Article 19 of the Labor Contract Law: If the term of a labor contract is more than three months but less than one year, the probation period shall not exceed one month; If the term of the labor contract is more than one year but less than three years, the probation period shall not exceed two months; The probation period of a labor contract with a fixed term of more than three years or without a fixed term shall not exceed six months.

The same employer and the same worker can only agree on a probation period.

A probation period may not be stipulated in a labor contract whose term is to complete certain tasks or whose term is less than three months.

The probation period is included in the labor contract. If the labor contract only stipulates the probation period, the probation period is not established, and this period is the term of the labor contract.

Labor Contract Law Article 82 If an employer fails to conclude a written labor contract with an 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.
