Does the new Alibaba customer service unit pay social security?

Social insurance belongs to national compulsory insurance. For units and employees, social insurance must be paid. Any unit or individual that establishes labor relations must participate in social insurance according to law. In other words, no matter whether the unit signs a labor contract with the employees or not, as long as the labor relationship is established, the unit must pay social insurance for the employees according to law. According to the law, employees should pay social security as long as they are employed in the month, and the employer should apply for social insurance registration with the social insurance agency within 30 days from the date of employment. However, due to the different time for social security departments in different regions to register and pay social security, it may happen that employees buy social security in the current month before the date of the current month, then buy social security in the next month and pay social security in the next month.
