I am an intern librarian from a supervision company. Sometimes some documents on the construction site need the director's signature. If the professional supervision engineer wants me to sign them, will I be responsible? This matter is easier to solve. Don't deliberately imitate the director's handwriting when signing. The font doesn't look like it can be rejected. If you have to sign it, call the director for advice and sign it if the director agrees, but don't forget to leave a record in the supervision log. If the director doesn't agree, there is no problem.
