The Resignation Letter: What to Write and What Not to Write
If you are leaving your job — whether voluntarily or because conditions have become intolerable — the resignation letter is a legal document, not a personal one. What you include can support a future claim. What you omit can weaken one. And what you write in anger can follow you for years.
A resignation letter feels like a formality — a courtesy to the employer, a notice that you are leaving, a closing of the chapter. In most resignations, that is exactly what it is. But when the resignation is connected to discrimination, harassment, retaliation, or intolerable working conditions, the letter becomes evidence. What it says — and what it does not say — will be scrutinized by the employer’s attorney, by the court, and potentially by a jury.
The employee who is leaving because of unlawful conditions faces a specific drafting challenge: the letter must preserve the constructive termination claim (if one exists) without oversharing, without waiving rights, and without providing the employer with material it can use against the employee.
If you are resigning because of intolerable conditions
A constructive termination claim requires the employee to show that working conditions were so intolerable that a reasonable person would have felt compelled to resign. The resignation letter is the moment when the employee’s reason for leaving is documented — and it should state the reason clearly enough to support the claim.
What to include:
State that you are resigning because of the conditions — not because you found a better opportunity, not because of personal reasons, but because the employer’s conduct left you no reasonable alternative. Be specific enough to identify the problem without writing a legal brief.
“I am resigning because the working conditions created by [describe the conduct — e.g., the retaliatory treatment I have experienced since filing my complaint on March 15, the ongoing harassment by my supervisor, the removal of my responsibilities following my return from medical leave] have made it impossible for me to continue in this position.”
This accomplishes two things. It identifies the reason for the resignation as the employer’s unlawful conduct — not the employee’s personal choice. And it creates a contemporaneous document that locks in the employee’s stated reason before the employer has a chance to recharacterize the departure as voluntary.
What to leave out:
Do not write an exhaustive recitation of every incident. The resignation letter is not a complaint or a legal filing. A brief, clear statement of the reason is sufficient. The detailed factual account belongs in the legal claim, not in the resignation letter.
Do not express gratitude for the opportunity. “Thank you for everything” is a sentence that the employer’s attorney will quote in every brief — arguing that an employee who was grateful could not have been working in intolerable conditions.
Do not apologize. “I’m sorry it came to this” implies that the resignation was a choice the employee regrets, rather than a consequence the employer created.
Do not threaten litigation. “I will be consulting with an attorney” is unnecessary (you should consult an attorney before the letter, not announce it in the letter) and it transforms a workplace document into a litigation threat, which changes how the employer receives and responds to it.
If you are resigning voluntarily
If the resignation is genuinely voluntary — you found a better job, you are relocating, you are leaving the workforce — the letter can be brief and neutral. There is no legal significance to the content, and a simple notice of the last day of work is sufficient.
“I am resigning from my position effective [date]. My last day will be [date].”
No explanation is required. No reason needs to be given. No gratitude needs to be expressed (though it may be appropriate if genuine). The shorter the letter, the less material it provides for any future dispute.
If you are being pushed out and haven’t decided whether to resign
If you are experiencing adverse treatment and are considering resignation but have not yet made the decision, do not write the resignation letter yet. Consult with an attorney first. The decision to resign — the timing, the manner, and the documentation — affects whether the resignation will be treated as constructive termination or as a voluntary departure.
In most cases, an attorney will advise against resigning unless the conditions are genuinely intolerable and the employee cannot continue. A resignation forfeits unemployment benefits and complicates the damages analysis. An employee who is being pushed out is generally better served by letting the employer make the termination decision — which preserves the wrongful termination claim, maintains unemployment eligibility, and avoids the burden of proving constructive termination.
If resignation is the right decision — because the conditions are truly intolerable, because remaining would cause serious harm to the employee’s health or wellbeing — the attorney can help draft the letter in a way that preserves the constructive termination claim.
The letter as evidence
Everything in the resignation letter is admissible. The employer will use it. If the letter says “I’m leaving for personal reasons,” the employer will argue the departure was voluntary. If the letter says “thank you for a wonderful experience,” the employer will argue the workplace was not hostile. If the letter says nothing about the reason, the employer will argue that the employee’s subsequent claim of intolerable conditions is a post hoc fabrication.
The letter should be written with this reality in mind. It is not a diary entry, not a cathartic exercise, not a final word to a supervisor who wronged you. It is a document that may be read aloud in a courtroom. Every word should serve the employee’s interests — and the employee’s interests are best served by clarity, brevity, and precision.
If you are resigning because of unlawful conditions, your resignation letter should state the reason — briefly, specifically, and without emotion. If you are resigning voluntarily, keep the letter short and neutral. In either case, consult with an attorney before you sign and send it. The resignation letter is evidence, and evidence should be created with care.
