How to write a resignation letter, and how much notice you actually owe

What the letter is actually for

A resignation letter is evidence. It establishes that the separation was voluntary, and it fixes the final date. Those two facts feed into unemployment eligibility, final-pay deadlines, benefits end dates, the clock on your equity, and any later argument about whether you left or were pushed. The tone of the letter is a professional matter. The date and the fact of voluntariness are the legal content.

This is why the advice to keep it short is not just etiquette. Every additional sentence is a sentence that can be quoted back. A letter that catalogues grievances undercuts a later constructive-dismissal argument if it also says you are grateful for the opportunity — and one that says nothing at all leaves the record clean.

Writing it

1. 1

   Check your contract first

   Find the notice clause before you write anything. It tells you the minimum period, whether notice must be in writing, and who it must go to. Check for a repayment clause too: signing bonuses, relocation costs and training fees are commonly repayable if you leave within a stated period, and the date you pick may sit either side of that line.

2. 2

   State that you are resigning, and from what

   One sentence naming the role. "I am resigning from my position as [role]." Do not write "I would like to resign" or "I am thinking of resigning" — either invites a conversation about whether it counts.

3. 3

   Give the final working date, not the notice length

   Write "my last day will be 12 September" rather than "I am giving four weeks' notice". A date cannot be miscounted, and it removes any argument about whether the period runs in working days or calendar days.

4. 4

   Offer a handover in one line

   A single sentence offering to document your work and brief a successor. It costs nothing, it is the part managers actually remember, and it is the thing most likely to produce a good reference later.

5. 5

   Leave out the reasons

   You are not required to give one, and anything you write becomes part of the record. If you have a genuine grievance, raise it through the grievance process as a separate document, on its own terms, before or alongside the resignation — not folded into it.

6. 6

   Send it to the right person, and keep proof

   Follow whatever the contract says about who receives notice. Email is normally fine and has the advantage of a timestamp. Copy your personal address, because access to work systems can be cut on the day you resign.

How much notice you actually owe

The two-week convention is American, informal, and not a legal obligation anywhere. What binds you is your contract, and — in systems with statutory notice — a floor set by legislation. These are quite different regimes, and people relocating between them routinely assume their home rule travels with them.

In the UK, section 86 of the Employment Rights Act 1996 requires an employee with at least one month of continuous employment to give not less than one week's notice, and that figure does not rise with service. The employer's statutory obligation does: one week for under two years, then a week for each complete year, capped at twelve. Contractual notice almost always exceeds both, and it is the contract that governs where it is longer.

In most US states you can walk out at the end of a shift without breaching anything, because the relationship was terminable at will in both directions. That does not make it costless — see the repayment and benefits points above — but it is not a legal wrong. Where an employment agreement does set a notice period, it binds, and the practical remedy an employer has is usually to withhold discretionary payments rather than to sue.

They do not have to let you work it

The most common surprise: you give two weeks and are told to leave that afternoon. In an at-will relationship this is entirely permitted, and unless a contract or a written policy provides otherwise, the employer generally has no obligation to pay you for the days you did not work. Whether that converts a quit into a discharge for unemployment purposes is a state-by-state question worth putting to your state agency before you set the date.

Where notice is contractual, the position reverses: the employer owes the notice pay whether or not it wants you in the building, and senior contracts routinely include a clause allowing them to require the period be spent away from the office while remaining employed and paid. If you are in a role with a long notice period and a competitor on the other side, expect that clause to be used.

What you are owed on the way out

Two things are commonly misunderstood, and both are state law rather than federal in the US.

• Your final paycheck. There is no federal rule requiring immediate payment on separation. State law sets the deadline, and it ranges from the next regular payday to within a small number of days, sometimes with different rules for a quit and a discharge. Check your state's payday requirements rather than assuming.
• Accrued unused leave. In some states — California, Colorado, Montana and Nebraska among them — accrued vacation is treated as earned wages that cannot be forfeited, and use-it-or-lose-it policies are prohibited. Illinois requires earned vacation to be paid out and specifically bars withholding it because an employee failed to give notice. In many other states payout depends on what the employer's written policy says, which is why the policy is worth reading before you set a date.

You cannot simply take it back

A resignation is notice, and notice once given cannot be unilaterally withdrawn. Retracting it requires the employer to agree. This is the mechanism behind the worst version of this situation: an argument, a sentence said in temper, and an employer that decides to treat it as final.

UK tribunals apply an objective test to those cases. In Omar v Epping Forest District Citizens Advice, the Employment Appeal Tribunal held that there is no separate "special circumstances" exception — the question in every case is whether, viewed objectively by a reasonable observer in the employer's position, the words were really intended as a resignation. Subsequent conduct is admissible where it sheds light on what was meant at the time, and a written resignation is much harder to argue was not seriously meant than words shouted across a room.

The practical rule follows directly. Do not resign in a meeting. Say you need to think, leave, and decide the next day. Nothing is lost by a day and a great deal can be lost by a sentence.

When it is not really a resignation

Constructive dismissal — constructive discharge in US terminology — is a resignation that the law treats as a termination, because the employer's conduct left no reasonable alternative. In the UK it is defined in the Employment Rights Act as terminating the contract in circumstances where the employer's conduct entitled you to leave without notice. In the US the test is whether working conditions were made so intolerable that a reasonable person would have felt compelled to resign.

The bar is high in both systems, and the mistakes people make are procedural rather than substantive. Resigning long after the conduct complained of can be read as having accepted it. Writing a warm resignation letter thanking everyone undercuts the claim that conditions were intolerable. And leaving without ever raising the issue internally removes the employer's chance to fix it, which tribunals and courts take into account. If you think this is your situation, take advice before you send the letter, not after.

The last thing to sort out

Before your access is cut, collect what you will need later and cannot get afterwards: your own copies of the employment contract, the handbook, any bonus or commission plan, and every equity document — grant notice, plan, and the post-termination exercise deadline, which is the term most likely to cost you money if you learn it late. Take your personal files, not company data.

Then ask for two things in writing. First, confirmation of your final date and what will be paid on it. Second, what the company will say to a reference enquiry, and who will say it. Both are ordinary requests while you are still an employee and awkward ones a month later, which is the whole reason to ask now.
