Worried About HR Verifying a Fake Admission Letter to Shorten My Notice Period?

Hi, my manager was not willing to reduce my notice period, so I lied to him that I am going for a master's. He asked me to provide documents, so I gave him the admission offer letter of my friend. I edited the name and sent it to the manager, who then forwarded it to HR for verification. How will HR verify this? Will they contact the university's admission director by email to get it verified?

Trainer Consult,

Forgive me for asking, but are you condoning people being dishonest in their dealings with their employers? Dishonesty will always be found out eventually and can have far-reaching consequences for a person's future career. Many people, even in the highest CEO positions, have found out to their detriment that, for example, lying on their CV is a sackable offense.
