Resigned

Last night I was chatting on messenger with a friend in the company i worked for. We were chatting about markets and how Indian software companies are planning to announce bonus at diwali etc. He said his boss "resigned" on papers. I said wat happened?. He said the boss had to do it because of mistakes in the work. I said how terrible, knowing the boss was my friend's mentor. He was surprised and asked y do i say so. And clarified re-signed (marked his sign again) on the bonus letters after getting the mistakes corrected. Wat say on that.
