Frequently Asked Questions
How long should a resignation letter be?
One page maximum — ideally 3 to 4 short paragraphs. State your intention to resign, your last working day, a brief thank-you, and an offer to help with the transition. That's all you need.
Do I have to give a reason for leaving?
No. You are under no legal obligation to explain why you are leaving. Stating 'I have decided to pursue a new opportunity' is completely acceptable and keeps the letter clean.
