A private dental clinic recruited a doctor. Can a non-practicing doctor be dismissed?

It is illegal for your clinic to use undocumented people as doctors. You can't do this in the first place.

Can be fired. However, wages must be settled on working days.

When employees take up their posts, you should first explain what treatment they are given without a license and what treatment they are given with a certificate. Treat him without a certificate first, and then treat him with a certificate.

If you have a certificate, you have never signed a contract, and there is no agreement on how much to deduct without a certificate, then it is illegal and unreasonable to deduct money. This is your own fault.
