Is it legal for restaurants not to pay social security to employees?

1. According to the provisions of China's Labor Law and Social Insurance Law, employers are obliged to buy social insurance for employees, including endowment insurance, medical insurance, work injury insurance, unemployment insurance and maternity insurance. The employer must pay social insurance premiums in accordance with the statutory proportion, and deduct the individual social insurance contributions from the wages of workers.

2. Social insurance is the legitimate rights and interests of employees, which can provide employees with pension, medical care, work injury and other protection, and employees can enjoy corresponding welfare benefits after leaving their jobs. If the restaurant does not pay social security to employees, it will deprive employees of the opportunity to enjoy these rights and interests, which violates the principle of protecting employees' rights and interests. Therefore, it is illegal for restaurants not to pay social security to employees.
