A resignation letter has exactly one job: to state, in writing, that you are leaving and when. It is not the place to air grievances, negotiate, or explain your life plans. Industries are small, references are forever, and the letter goes in a file — so the winning move is short, warm, and unambiguous. This guide gives you the letter, the variants, and the order of operations around it.

Before the letter: the conversation

Tell your manager face to face (or on a call) before any written notice circulates. Nobody should learn you are leaving from an email. Keep the conversation simple:

“I wanted to tell you directly: I’ve accepted another opportunity and I’m resigning. My last day will be {{Last day, honoring your notice period}}. I want to make the transition as smooth as I can, and I’d like to talk about how to hand things over.”

Then send the letter the same day, so the paper trail matches the conversation.

The standard letter

“Dear {{Manager name}},

Please accept this letter as formal notice of my resignation from my position as {{Your role title}} at {{Company name}}. In line with my notice period, my last working day will be {{Last day}}.

I’m grateful for the opportunities I’ve had here — in particular {{One genuine specific: a project, a skill, a team}}. Thank you for that.

Between now and my last day, I’m committed to a clean handover. I’ll document my ongoing work, brief {{Colleague or team}}, and close out {{Key responsibility}} — and I’m happy to prioritize whatever makes the transition easiest for the team.

Thank you again, and I wish the team continued success.

Sincerely, {{Your name}} {{Date}}”

Variant: short or immediate notice

When circumstances require leaving faster than the standard notice, acknowledge it plainly and offer what you can:

“Please accept this letter as formal notice of my resignation from my position as {{Your role title}}, effective {{Date}}. I recognize this is shorter notice than usual, and I apologize for the disruption. To soften it, I will {{What you can offer: complete handover documentation, remain reachable for questions for two weeks, finish a named deliverable}}. Thank you for your understanding.”

Variant: staying flexible on the end date

If you have goodwill and some slack in your start date, this line buys enormous goodwill:

“My last working day will be {{Last day}}; if a modest adjustment to that date would materially help the handover, I’m open to discussing it.”

Only offer this if you mean it — and never let the end date drift past what your next employer needs.

What stays out of the letter

• Reasons. “I’ve accepted another opportunity” is a complete explanation. Criticism belongs in an exit interview, if anywhere, and only what you would say to someone’s face.
• Negotiation. If you would stay for the right counteroffer, have that conversation before resigning, not through the letter.
• Emotion in either direction. Neither grievances nor three paragraphs of gratitude. One warm sentence is the right amount.
• Promises you can’t keep. Do not commit to “anything you need” — commit to the specific handover you can actually deliver.

After you hand it in

• Keep working like a professional until the last hour. Your final two weeks are the reference someone gives about you for the next decade.
• Write the handover document you wish you had inherited: systems, statuses, contacts, passwords-locations (never the passwords themselves), and open decisions.
• Confirm the practical details in writing before you go: final pay date, unused leave, benefits end date, and equipment return.
• Say individual goodbyes to the people who mattered. Bridges are built one person at a time.
