If you are an employee, if you don't pay social security for 4000 packs of food and clothing in Guangzhou, your labor rights and interests may have been damaged. According to the Labor Law of People's Republic of China (PRC), the employer shall pay social insurance for employees, including endowment insurance, medical insurance, unemployment insurance, work injury insurance and maternity insurance. At the same time, employers should also abide by the minimum wage and working hours. If you don't get the corresponding welfare treatment in the salary of 4000 yuan, I suggest you consult the employer or the local labor and social security department in time to safeguard your legitimate rights and interests.
