What To Include And Leave Out Of A Resignation Letter
Related tool: AI Resignation Letter Generator
A resignation letter needs surprisingly little: your intent to resign, your title, and your last working day. Most of what people agonize over adding isn't actually necessary.
Leave out a detailed explanation of why you're leaving, criticism of the company or specific people, and promises about the future you can't guarantee. All three tend to create more risk than benefit once the letter is on file.
Remember that a resignation letter is a permanent record, potentially reviewed well beyond your manager — HR, future reference checks, even legal review in rare disputes. Writing it with that audience in mind, not just the person you're handing it to, changes what's worth including.
A short note of thanks, even if brief and general, costs nothing and leaves a better final impression than a letter that reads as purely transactional.
If you're leaving on genuinely difficult terms, keeping the letter especially short and neutral protects you more than trying to explain or justify the situation in writing.
