The labor bureau can write a resignation report to solve this problem first. If they tear it, they can sue him directly at the labor bureau. He said that he would be given time if he was approved, and the time would not exceed one month at most. He can ask to pay you double salary because he didn't sign a labor contract. If he doesn't buy social security, the boss will definitely be fined. If he has a business license and is a legal representative, it will be very strict.
