Job Offer Letter: Format, Example, and the Clauses

The clauses that carry the risk

The first thing to know is that the main protection most drafting guides promise does not exist. Preserving at-will status does not defeat a claim over a withdrawn offer. In Grouse v. Group Health Plan, Inc. the job on offer was at-will, and the employer was still liable to a candidate who had resigned his existing job and turned down another in reliance on it. At-will status is what stops the promise being an enforceable contract, which is exactly why the claim proceeds in promissory estoppel instead. The disclaimer is not a shield against that.

Promissory estoppel is state common law and the states split hard on whether relying on an at-will offer is reasonable at all. Minnesota, California, New Jersey, Massachusetts and Illinois have let candidates recover; New York, Texas, Wisconsin, Indiana and Missouri have generally refused, reasoning that an at-will offer promises nothing you can rely on. Where the claim runs, it asks for a clear and definite promise of employment, an employer who should have expected it to induce action, a candidate who actually acted by resigning, relocating, or spending money, and a conclusion that injustice can be avoided only by enforcing the promise. Which state's law applies matters more than any sentence in your template.

So the clauses below are worth writing, but for a narrower reason than the usual one: they decide what the argument is about.

• The at-will statement. A line saying employment is at-will and may be ended by either party at any time, with or without cause or notice. It belongs in almost every US offer letter, but not all. Montana stops being at-will once an employee clears probation, and the statutory fallback probation is a full year, extendable to eighteen months. Puerto Rico is not an at-will jurisdiction at all: an indefinite-term employee discharged without just cause is owed statutory severance under Act 80 of 1976. For a role in either, take the line out.
• The not-a-contract disclaimer. A line saying the letter is not an employment contract for any fixed term. Without it, a detailed letter about salary, bonus, and duration starts to look like one.
• The contingencies, named individually. "Subject to a satisfactory background check, two references, and proof of eligibility to work" is a condition a court can test. "Subject to pre-employment requirements" is not. Naming them does not stop a claim; it narrows it to one question, whether the condition genuinely failed, which is a far better argument to be having than one about what you promised.
• The background check has its own rulebook. If a screening company runs it, the Fair Credit Reporting Act applies. Before you order the report you need a stand-alone written disclosure and the candidate's written authorisation. Before you rescind on the strength of it you must send a pre-adverse action notice with a copy of the report and the CFPB summary of rights, leave a real window for the candidate to dispute what it says, and only then send the adverse action notice. Rescinding the same day the report lands skips a step the statute requires. State law can add more: Washington's Fair Chance Act, in force since 1 July 2026 for employers with 15 or more staff, restricts when criminal record information can be obtained at all.
• The conditional offer is what makes medical screening lawful. Under the Americans with Disabilities Act an employer cannot ask about disability or require a medical examination before making an offer. After a real offer it can, provided the examination is required of everyone entering that job category. If your role needs a fitness assessment or a drug screen with a medical component, the offer letter is the document that unlocks it, which is an argument for making the offer properly rather than informally.

Estoppel is also not the only exposure. Withdrawing an offer for a reason connected to a protected characteristic is a discrimination claim, and in Britain a job applicant is protected in the terms on which employment is offered and in a refusal to offer it, whether or not any contract ever formed.

None of this is a licence to withdraw casually. If a candidate has already resigned on the strength of your offer, the exposure is normally measured by what they gave up in reliance, the earnings from the job they left, the other offer they declined, the money spent relocating, rather than by the salary you promised. That was the measure in Grouse.

What goes in the letter

• Job title and reporting line. Who they are, who they report to, and where the role sits.
• Start date, and whether it is fixed or subject to the conditions clearing.
• Compensation. The base figure with its period stated (per year, per month), plus bonus or commission with how it is calculated and when it is paid.
• Hours and location, including remote or hybrid expectations and any required office days.
• Benefits in outline, with a pointer to the plan documents rather than a summary that might contradict them.
• Probation, where you use one, with its length and what happens at the end.
• Contingencies, listed one by one. Do not ask for right-to-work documents before the candidate accepts: the employee completes section 1 of Form I-9 no later than the first day of employment and not before acceptance, and the employer completes section 2 within three business days of the first day of work for pay. Demanding a particular document, or extra ones, invites a claim of its own.
• The at-will and not-a-contract lines for a US role.
• An acceptance deadline. A week or more is the working norm, and a 24-hour "exploding offer" reads as pressure and costs you candidates. No general law sets a minimum, so this one is judgment rather than a rule.
• The state wage notice, where one is required. New York and California both require a written notice at hiring, in the employee's language, with prescribed contents. That is a US obligation, not a foreign one, and the offer letter does not automatically satisfy it.
• How to accept, and who to contact with questions.

Outside the US

• Great Britain: England, Wales and Scotland. There is no at-will doctrine, so delete that line, and understand why it would not help you anyway. Once the candidate accepts, verbally or in writing, a contract of employment exists, subject only to the offer being unconditional or its conditions met. Withdrawing an accepted offer whose conditions were satisfied is a breach of contract, not a change of mind. The employer must give the written statement of employment particulars on or before the first day: that day-one deadline covers the principal statement, while a second tier including pensions, collective agreements, training entitlement, and disciplinary and grievance procedures may follow up to two months after the start. A single combined document can do the job, and Acas publishes an offer letter with the written statement built in.
• Northern Ireland is separate. The written statement there is still due within two months of the start of employment rather than on day one, under Article 33 of the Employment Rights (Northern Ireland) Order 1996. Do not apply the Great Britain deadline to a Belfast hire.
• The European Union. Under the transparent and predictable working conditions directive the information may sit in the employment contract itself, with the core particulars due within seven calendar days of the start and the remainder within a month. Member states implement it differently, so check the national law rather than the directive.
• India. The labour codes that took effect in November 2025 make a written appointment letter compulsory for every worker, permanent, fixed-term, contract or gig. In practice the offer still comes first and the appointment letter carries the full terms, but do not treat the offer as unenforceable in the meantime: an accepted offer supported by consideration can already be a contract, and candidates who resigned in reliance on withdrawn offers have recovered damages. Keep the offer short, spell out every condition precedent, and get the appointment letter right because it is now a statutory document.
• Australia. The letter of offer, once accepted, is the employment contract. There is no appointment-letter stage to fall back on, so the offer has to be right the first time and has to sit consistently with any applicable award or enterprise agreement.

The template

Before you send it

• Check the figures against the requisition and the band, because a number in an offer letter is very hard to walk back.
• Know what a verbal offer costs you. In the US, calling first and sending the letter the same day lets you hear hesitation before anything is in writing. In Britain it does the opposite: a clear verbal offer accepted on the phone forms the contract there and then, so if you want the conditions to bind, say them on the call or do not make the offer on the call.
• Do not promise what you have not confirmed, particularly bonus amounts, a title change later, or a start date that depends on a check nobody has run.
• Give a real deadline, a week or more, and hold to it rather than extending it three times.
• Keep the letter and the contract consistent. Where a fuller agreement or appointment letter follows, read them side by side before either goes out.
