If a person write this kind of resignation letter, it will come back to haunt the person.  If I know of any person that write this kind of letter, the person will be forever blacklisted and never hire by me.  This is highly unprofessional.

There are times and places that you do not joke about something.  And, there are people that do not understand you do not put anything on a formal letter like a resignation letter that might harm you.

Once I know someone that is resigning from my company.  He was putting in his two weeks notice and then he is going to a surgery while using his vacation days.  But, he made a crucial mistake.  He said I resigned on the letter as opposed to this letter served as two weeks' notice.  So, he was out of the company on that day and he ended paying thousands of doillar of his own money for his surgery.

DO NOT TRY TO BE FUNNY WITH YOUR RESIGNATION LETTER.

Keeps me wondering why people resign already still got the mood to write this kind of long-winded letter instead of focusing on transition and enjoys the rest of the days in his would-be ex-company.
