When the supermarket enters the market, the health certificate placed in the personnel department has expired. Do I need to go through exit formalities and return my expired health certificate after leaving my job?
There is no point in the expiration of the health certificate. Whether to apply for a refund depends on personal wishes.
Both employees and those who enter the venue need to go through the relevant exit procedures at the personnel department when they leave. At that time, you can ask for their previous health certificates by the way. After all, there is personal information on it.
