If the company does not require continuous resume filling, or if there is, but the staff did not find any interruption in the resume during the audit, and did not ask whether there was any illegal or criminal behavior when applying for the job, they can ask the company to give financial compensation according to the regulations when leaving the company. However, if you have been employed for less than half a year, you'd better not mention salary-sometimes it's really unnecessary to take money so seriously.
If the employee conceals the criminal record, which causes the employer to make an employment decision against his true meaning, the employer may terminate the labor contract. How to judge whether to conceal it depends on whether there are clauses in the labor contract signed between the employer and the employee that are similar to "should truthfully inform the employee that he has been subjected to criminal punishment" and "has no criminal record", whether to truthfully fill in the applicant registration form and criminal record, and whether to truthfully fill in the resume.
If there are no clear restrictions on employees in relevant national policies, laws and regulations, the company needs to explain the legality and rationality of requiring employees to provide proof of no criminal record in this position, otherwise the company will be suspected of employment discrimination or illegal dismissal.
The company has no right to check a person's criminal record. The company can ask you to provide a "certificate of innocence", so that once the crime is sentenced, the record can follow you for life. If your criminal judgment is online, the company can find it.
If he concealed this situation from the company when he joined the company, the company should be able to persuade him to leave on the grounds that he provided false information when he joined the company. Anyone who commits crimes during his tenure will be dismissed by the company.
