Every employer should be aware of whether a potential employee, an applicant for a vacancy, or just a suspicious employee had a previous criminal record. Quite often, such data are needed when entering the internal affairs bodies, or for leading positions.
If your employee has nothing against your desire to check him, then feel free to send him to the information and analytical center at the local ATC. There he must receive a special certificate of the presence or absence of a criminal record.
If the future employee of your organization refuses this check, it is necessary to enter in the applicant's questionnaire a clause on providing information about the presence or absence of a criminal record. In this case, when collecting the necessary certificates, the potential employee will be obliged to provide this one too.
You can do without involving the employee himself in the process. Provided that your company has its own security service. She has the right to submit inquiries to the Ministry of Internal Affairs or ATC. However, first make sure that the request goes through your organization's HR department. In this case, the internal affairs bodies provide all the information without any problems.
