If your company is a regular company, there must be a column filled in by newcomers in your resume, and they need to make a commitment to the authenticity of the information they provide with their autographs. If the newcomer is still in the probation period, the personnel department can dismiss him/her on behalf of the company because of his/her false promises and personality problems. If your company has corresponding rules and regulations, you can dismiss it as easy as blowing off dust, but only if you report to your superiors in advance and get a unified operation route with them first.

But if it is not a regular company, then turn a blind eye. Leaders usually pay more attention to performance.

If you have a personal grudge, I suggest watching the TV version of Du Lala's promotion.
