TL;DR
A resignation letter needs three things: a clear statement that you are resigning, your last working day, and a brief thank-you. Nothing else is required. Tell your manager verbally first - the written letter is a formality, not a conversation starter. Do not include reasons for leaving, grievances, or salary comparisons. Keep a copy before you send it.
Most resignation letters fail not because they are too short but because they are too long. People feel compelled to explain themselves, justify the timing, or soften the blow with qualifiers. The result is a letter that creates problems rather than closing a chapter professionally.
This guide covers exactly what to include, what to leave out, how notice periods work in the US and UK, and a template you can adapt in five minutes.
What a resignation letter actually does
A resignation letter is a legal and HR record. It documents that you gave notice, when you gave it, and when your last day will be. That is it. It is not a performance review, a negotiation, or a venue for feedback.
HR teams file resignation letters to calculate final pay, update headcount, trigger offboarding processes, and confirm your notice period start date. Some employment contracts specify that notice must be given in writing - the letter is what makes the notice legally binding in those cases.
Save a copy before you send
Send the letter to your manager and CC HR. Keep a copy in your personal email or files. If there is ever a dispute about when you gave notice, you want a timestamped record you control.
The three required elements
Every resignation letter needs these three things. Nothing else is required.
A clear resignation statement
State plainly that you are resigning from your position. Name the role and the company so there is no ambiguity. "I am writing to formally resign from my position as [Job Title] at [Company]." That one sentence is enough.
Your last working day
Give a specific date. Count forward from today by the notice period required in your contract or the local standard. Two weeks is the norm in the US; check your contract for the UK. The date removes any ambiguity about when HR should stop your pay and benefits.
A brief thank-you
One or two sentences acknowledging the opportunity and wishing the team well. This keeps the door open and sets the tone for the rest of your notice period. It does not have to be effusive - just professional and genuine.
What to leave out
The things people most want to include are the things most likely to cause problems.
| Leave it out | Why |
|---|---|
| Your reasons for leaving | Can be misquoted, held against you, or make a handover awkward. If you want to give feedback, do it in an exit interview instead. |
| Grievances about managers or colleagues | Creates a paper trail that could follow you if references are checked or a dispute arises. Your employment ends; the letter stays on file. |
| Salary comparisons or counter-offer language | If you have already decided to go, negotiating in the letter undermines the resignation and muddies what is meant to be a clean exit. |
| Future plans | Where you are going is your business. You are not obligated to say, and sharing it sometimes triggers unnecessary friction or attempts to interfere. |
| Lengthy praise or excessive apology | Keeps the letter clean and prevents it reading as an attempt to soften bad news. Professional and brief is more impressive than over-explained. |
There are no hard legal rules against including any of these - they are practical guidelines for keeping the exit smooth and your record clean.
The conversation first rule
The letter should never be the first your manager hears of your resignation. Tell them verbally - in person or by video call if remote - before anything is committed to writing. This is the professional norm in almost every industry and culture, and skipping it will be remembered.
The conversation is where the actual resignation happens. The letter follows within the same day or the next business day as the formal written record. If you cannot reach your manager before you need to trigger the notice period, a brief email to both your manager and HR is acceptable, but note in it that you will follow up verbally.
Do not send the letter before the conversation
Sending a resignation letter before speaking to your manager reads as avoidance, and in a small industry it damages a relationship you may need later. The conversation is harder but it is the right sequence.
Notice period norms
The notice period you give should match what your contract specifies. If your contract is silent, the local norm applies.
United States: Two weeks is the standard across most industries and seniority levels. The US has no federal statutory notice requirement - notice is set by your employment agreement, not law. Senior roles sometimes carry 30 or 60 days by contract.
United Kingdom: The UK sets statutory minimum notice periods by law: one week after one month of employment, rising by one week per year of service up to a maximum of 12 weeks for 12 or more years. Your contract may specify a longer period - that contractual period takes precedence if it is longer than the statutory minimum. One month is common for professional and managerial roles.
In both markets, your employer can agree to release you earlier (a shortened notice by mutual agreement), or in some cases pay you in lieu of notice rather than having you work the period. Get any shortened-notice agreement in writing.
Email vs letter vs printed copy
For most roles in 2026, email is the right channel. It is immediate, creates a timestamped record, and satisfies the "written notice" requirement in most contracts. Address it to your direct manager and CC HR.
A printed copy handed to HR is occasionally expected in more formal organisations - regulated sectors, government roles, or very traditional companies. If in doubt, send the email and ask HR whether they also need a signed physical copy.
Resigning by text message, WhatsApp, or Slack is generally accepted only for very informal workplaces where that channel is how everything is communicated. When in doubt, use email.
A resignation letter template
The template below covers everything required and nothing more. Fill in the bracketed fields and send.
| Section | What to write |
|---|---|
| Subject line | Resignation - [Your Name] - [Job Title] |
| Opening line | I am writing to formally resign from my position as [Job Title] at [Company Name]. |
| Last day | My last working day will be [Date], in line with [my notice period / the two-week standard / my contractual notice of X weeks]. |
| Thank-you | I am grateful for the opportunity to work at [Company] and for the support of the team during my time here. |
| Handover offer | (Optional) I am happy to assist with handover during my notice period and will do my best to leave things in good order. |
| Close | Kind regards, [Your Name] |
Keep the letter to four or five sentences total. Brevity reads as professional, not cold.
What happens after you send it
Once the letter is sent, your notice period starts. A few things to keep track of:
Agree a handover plan with your manager
Document what you are working on, where files live, and who is the right contact for ongoing projects. A clean handover protects your reference and makes the exit smoother for your team.
Confirm your final pay and holiday entitlement
Ask HR how any unused holiday (PTO) will be handled - it is usually paid out in your final paycheck in the US, and in the UK you are entitled to be paid for accrued but untaken statutory holiday. Get the calculation in writing.
Ask about the reference process
Check who at the company will be your reference contact going forward, and whether there is a standard reference policy (some companies only confirm dates and job title). Better to know now than to find out during a background check.
Return company property
Laptop, phone, access cards, and any other equipment. Make sure you have this scheduled before your last day to avoid delays to your final pay.

Starting your next job search
Once you have confirmed your leaving date, it is worth getting your job search moving before your notice period ends. Roles can take four to eight weeks to process from application to offer, so starting early keeps you from having a gap you did not plan for.

Frequently asked questions
Do I have to give a reason for resigning?
No. You are not legally required to give a reason, and in most cases you should not. A resignation letter is a formal record that you are leaving and when - nothing more. Reasons can be used against you, misquoted, or make a difficult conversation harder. If asked directly by your manager, a brief neutral phrase such as “I have decided to pursue a new opportunity” is enough.
Can I resign by email?
Yes, email is acceptable and is now the standard in most industries. It creates a written record with a timestamp, which is exactly what you need. If your contract specifies written notice, email satisfies that in most jurisdictions. For senior roles or longer tenures, some people also hand a printed copy to HR after sending the email, but it is not required.
What if I want to leave immediately?
Leaving without working your notice period is possible but has consequences. Your employer can withhold pay for the notice period you skipped, and it can affect your reference. In the UK, leaving before your statutory or contractual notice expires is technically a breach of contract. If you need to leave urgently - for health, safety, or a hostile environment - take legal advice before sending anything.
Will resigning affect my reference?
A professional resignation almost never damages a reference. What damages references is how you behave during your notice period - whether you hand over work properly, stay engaged, and leave on good terms. A resignation letter that is short, neutral, and grateful sets the right tone for everything that follows.
Ready to find your next role?
MORT scans thousands of company career pages, scores every job 0-100% for fit with your skills and experience, and generates a tailored resume for each application - so you spend your time on roles where you are genuinely a strong match, not on ones that will never convert.
