A resignation letter or resignation email is a formal record for HR and your employee file that you are quitting. It gives your employer notice of when your last day of work will be so that they have time to find a replacement or train someone else to cover the duties they hire someone.
Your resignation letter should be courteous and professional. Remember that this is not the time to vent about your horrible boss or co-workers or make accusations. Keep the letter positive, and focus on the fact that you are moving on to new opportunities.
There is no need to beat around the bush – state your intention to resign clearly and directly. Don’t use vague language or bury the point of your letter.
Give a specific date for your last day of work so your employer has time to plan for your departure and find a replacement.
