If unemployment insurance is broken, it can be made up. According to Article 44 of the Social Insurance Law of the People's Republic of China, employees shall participate in unemployment insurance, and the employer and employees shall jointly pay unemployment insurance premiums in accordance with state regulations.
 Therefore, only employees of the unit can pay unemployment insurance. If the unemployment insurance payment is interrupted due to personal reasons (job hopping, resignation, etc.), it cannot be supplemented. However, if the unemployment insurance of employees is not paid due to the unit, the unit can apply for supplementary payment.
 [Legal basis] According to Article 44 of the Social Insurance Law of the People's Republic of China, employees shall participate in unemployment insurance, and the employer and employees shall jointly pay unemployment insurance premiums in accordance with state regulations.
