Put it this way. If someone is prepared to lie on a document to get a job, then as an employer if I found out about it would I really trust that someone with confidential information? Or money? No, of course I wouldn't. I would never be able to trust them with anything.
Being good at your job is fine, but if you lied to get it then you've no respect due.
