How to resign without burning anything down
A resignation letter has one job: to put your departure and your exact last working day on the record, clearly and without drama. Everything else in the letter is optional, and most of it is better left out.
What the letter must include
Your job title, a plain statement that you are resigning, your exact last working day, and an offer to help with the transition. That is the whole checklist. Anything beyond that is a choice, not a requirement.
What to leave out
Grievances, feedback about your manager, and negotiation. The letter goes in your permanent file and may be read by people you have never met. Save honest feedback for the exit interview or a private conversation, and negotiate a counteroffer before you resign, not inside the letter.
Two weeks is convention, not law
In most US at-will jobs, no statute requires notice. Two weeks is the professional convention because it protects references and bridges. Check your contract or offer letter first: some roles, especially senior ones, specify 30 or 60 days.
Tell your manager first, letter second
Resign in person or on a call, then send the letter as the written record of what you already said. A resignation your manager first learns about from HR paperwork lands badly, and the manager is usually your most important future reference.
The company can end it early
In an at-will job, an employer can accept your resignation effective immediately, and some do, especially for roles with sensitive access. Assume you could lose system access the day you resign, and have your personal logistics ready before you send anything.
Reasons are optional
You do not owe an explanation. If you give one, keep it to a single neutral clause: accepted another role, personal reasons, relocating. A neutral reason closes the topic; a detailed one opens a debate.
