What if a 50-year-old factory doesn't buy social security?

Legal analysis: if the unit fails to pay social security, the employer shall pay social security for the employee within 30 days from the date of establishing labor relations with the employee, and the employee may ask the employer to pay five insurances. If the employer delays payment for various reasons, the employee can register the complaint in the real-name registration system of the local labor inspection brigade with the original ID card and the proof of the factual labor relationship with the employer. First of all, workers can apply for labor arbitration and demand to pay back the five insurances.

Legal basis: Article 84 of People's Republic of China (PRC) Social Insurance Law. If the employer fails to apply for social insurance registration, the social insurance administrative department shall order it to make corrections within a time limit; If no correction is made within the time limit, the employer shall be fined more than one time and less than three times the amount of social insurance premiums payable, and the directly responsible person in charge and other directly responsible personnel shall be fined more than 500 yuan and less than 3,000 yuan.
