How to Write a Resignation Letter (Short, Professional, Done)
Most people spend more time on the goodbye email to their team than on the actual resignation letter. That's backwards. Here's what the letter needs — and what it really doesn't.
Why it still matters even when it feels like a formality
Honestly, a resignation letter does feel like a formality — and in a lot of ways it is. But it's also a legal record of your notice period, your last day, and the fact that you left on your own terms. Companies keep these on file, and HR departments reference them.
The tone you leave with follows you. References, rehires, professional relationships — they don't end when you walk out. A clean, professional letter costs you nothing and protects everything.
What to include (and nothing more)
Three things. Your intention to resign. Your last working day. A brief, genuine thank you. That's it — and I mean that literally. Anything beyond those three things is either unnecessary or a risk.
You don't need to explain why you're leaving. You don't need to detail your next move. You don't need to itemize everything you've contributed over the years. Short is professional. Long is suspicious.
The template
Dear [Manager Name],
I'm writing to formally notify you of my resignation from [Role Title] at [Company]. My last working day will be [Date], giving [X] weeks notice as required.
I've appreciated the opportunity to work here and I wish the team well going forward.
[Your Name]
Under 100 words. Clear last day. No complaints. That's the whole thing.
How much notice is actually standard
Two weeks is the default in most industries. That said, check your employment contract first — some roles require 30, 60, or even 90 days, and ignoring that can have financial or legal implications.
If you're in a senior role or leaving a small team, giving more notice than required is often worth it, it costs you a couple of weeks and buys you goodwill that can last years. That trade is usually worth making.
What not to put in writing
Here's the thing — don't put anything negative in writing. Not the reason you're leaving, not your frustrations with management, not the project that burned you out. Even if you're leaving because of genuinely difficult circumstances, the letter isn't the place.
Those conversations can happen in person — or not at all. But once something is in a written record, it can travel. The professional world is smaller than most people realize, and a gracious resignation letter from a job you hated costs nothing.
How to deliver it
Tell your manager in person or on a video call first. The letter is a follow-up to that conversation, not a substitute for it. Walking in and dropping a letter without warning is awkward for everyone and signals poor judgment.
Keep the conversation brief. "I've decided to move on, my last day will be [date], and I've put it in writing" is enough. You don't owe a full debrief — just professionalism.
