A letter of resignation is a formal written notice that you're leaving your job. It's not legally required in most at-will employment states, but it's a professional courtesy that protects your reputation and maintains your references.
What to include
- Clear statement of resignation — "I am writing to resign from my position as [Title], effective [Date]."
- Last working day — specify the date. Two weeks' notice is standard but not legally required.
- Transition plan — offer to help train your replacement or document your current projects.
- Gratitude — a brief, genuine thank you. Even if you're leaving on bad terms, keep this professional.
What not to include
- Reasons for leaving — you're not obligated to explain, and anything you write could be used against you.
- Complaints about colleagues or management — save that for an exit interview, not a written record.
- Emotional language — keep it factual and professional.
- Negotiation attempts — if you want a counteroffer, have that conversation in person, not in writing.
A resignation letter is not a negotiation tool. If you're hoping for a counteroffer, talk to your manager first. Once you've submitted a written resignation, the dynamic changes.
Timing and delivery
- Two weeks' notice — the professional standard, though not legally required.
- Submit to your direct supervisor — not HR, not a colleague. Follow your company's specific procedure.
- Keep a copy — date it and keep proof of delivery (email with read receipt, or hand-deliver with a signed acknowledgment).
After you resign
- Return company property — laptop, badge, keys, documents.
- Update your accounts — change passwords, transfer files, update signatures.
- Document your work — create a transition document for your replacement.
- Request a reference — ask your manager or colleagues for a LinkedIn recommendation or reference letter before they forget.
Make it legal
A resignation letter doesn't need to be "legal" — it's a professional document. But if you're under a contract (non-compete, severance agreement, employment agreement), review those terms before resigning to understand your obligations.
A professional resignation letter drafted to your situation takes about ten minutes.
