Can I work in a factory without buying social security?

Legal analysis: No, social insurance is compulsory by the state, and it is the legal obligation of the employer to handle social insurance for employees. Neither employers nor employees can dispose of this right and obligation at will. It is illegal and invalid to sign an agreement with the employer voluntarily to give up participating in social insurance. As an invalid agreement, it is not legally binding on workers and employers, and the company should still bear the obligation to pay social insurance for employees.

Legal basis: Article 72 of the Labor Law of People's Republic of China (PRC) determines the sources of social insurance funds according to the types of insurance, and gradually implements social overall planning. Employers and workers must participate in social insurance and pay social insurance premiums according to law.
