If the employee unit wants to apply for unemployment certificate, such as my social security, what impact will it have on me?

It makes no difference. Unemployment certificates have been abolished for a long time in various places. Now this certificate is called employment and entrepreneurship certificate, which is used to record your employment and unemployment. According to the regulations, it is necessary for all unemployed people. On-the-job status is not required, but employment registration is required. After being unemployed, there will be on-the-job and unemployment records on it, which is also a necessary voucher for receiving unemployment insurance benefits.
