Best way to put papers!

My friend recently had offer with 50% hike. They were ok with 3 months notice period. My friend, instead of directly sending the resignation mail, wanted to made it dramatic. So he wrote an email with all management in CC to confirm his travel date by EOD as management is delayingthe same for a long time( he was promised for onsite but it was never meant to be done), else he would resign. He showed that mail to his team members as well. He knew that management will think that he is just trying to push them and will not any such thing.

Next day he sent resignation mail, which he was anyway going to do. He is now a Hero and talk of the town. 😅😅

Do you guys have any such interesting experience related to putting papers??
