The company didn't buy social security, are they all sporadic wages?

Hello, I'm glad to answer your question. Now, according to national regulations, the unit must pay social security to its employees. Those who don't pay social security are often temporary workers or odd jobs. They do it here today and there tomorrow, which makes it very inconvenient to pay social security. These people can pay their own social security through flexible employment. The above is my personal opinion, for reference only, hoping to help you.
