An offer letter is the first document of the employment relationship and the first exhibit in a dispute about it. The recurring failure mode isn't what's missing — it's what the letter accidentally promises: a year of employment, a guaranteed bonus, an exempt classification the role can't support. Eight checks before you hit send.
Why it matters: The at-will statement is boilerplate; contradicting it two paragraphs later is the classic mistake. "We look forward to many years together," "your first annual review will be in June," or probationary-period language implying job security afterward all give a plaintiff's attorney implied-contract material. The letter should also say only a named officer can modify at-will status, in writing.
Check: One clear at-will paragraph, nothing elsewhere implying duration or guaranteed continued employment, and a sole-modification clause.
Why it matters: Some courts have treated "your salary will be $120,000 per year" as evidence of a one-year employment term — exactly the implied contract the at-will clause was supposed to prevent. It's a minority position, but the fix costs nothing.
Check: Pay is stated per pay period ("$4,615.38 per bi-weekly pay period, annualizing to approximately $120,000"), matching the payroll calendar.
Why it matters: Calling a role "exempt" in the offer letter doesn't make it exempt — FLSA exemption depends on the salary threshold and the duties test, and misclassification claims (back overtime, liquidated damages, multi-year lookback) are among the most expensive HR mistakes. The offer letter is where the misclassification gets memorialized.
Check: Exempt/non-exempt designation has been analyzed against the actual duties and current salary thresholds — federal and state, since states like California and Washington set higher bars — before it goes in the letter.
Why it matters: "You will receive a $20,000 annual bonus" is a debt; "you will be eligible to participate in the bonus program, with a target of $20,000, subject to plan terms and company discretion" is a program. Vague commission language is worse: several states (California among them) require commission agreements in writing with the calculation method, and disputes about post-termination commissions are a staple of wage litigation. Equity promises that don't reference the plan and vesting schedule invite claims the letter itself granted the shares.
Check: Variable pay says "eligible," references the governing plan document, states when a bonus/commission is "earned," and defers equity terms to the plan and grant agreement (board approval included).
Why it matters: A contingency that isn't in the letter doesn't exist when you need it. Background check, I-9 work authorization, reference and license verification should all be stated. The background check carries its own trap: the FCRA requires a standalone disclosure and written authorization (not buried in the offer letter or application), and rescinding based on results requires the two-step adverse-action process — pre-adverse notice with the report, waiting period, then final notice. Many states and cities layer ban-the-box timing rules on top.
Check: All contingencies listed; the FCRA disclosure is a separate document; adverse-action procedure is followed before any offer is pulled; local ban-the-box rules honored.
Why it matters: "You'll sign our standard agreements on day one" can void a non-compete entirely. Massachusetts requires the non-compete with the formal offer or 10 business days before start, whichever is earlier; Illinois gives candidates 14 calendar days to review; Colorado requires separate advance notice; Washington requires disclosure no later than acceptance. And in California, Minnesota, North Dakota, and Oklahoma, most employment non-competes are banned outright — offering one there creates risk instead of protection.
Check: Any NDA, non-compete, non-solicit, or arbitration agreement is attached to the offer, with state notice periods honored — and no non-compete offered in ban states.
Why it matters: States like Colorado, California, Washington, and New York require pay ranges in job postings — and an offer that lands outside the posted range, or wildly different offers for the same posted role, become evidence in pay-equity claims. Salary-history bans in many states also mean the offer can't be justified by "what they made before."
Check: The offer falls within the posted range (or the range is updated), and compensation was set without reference to salary history in ban states.
Why it matters: Candidates hear things during recruiting: "you'll get a promotion within a year," "remote forever," "the bonus always pays out." An integration clause — this letter supersedes all prior discussions and representations — is the cheapest protection in the document. Without it, every enthusiastic recruiting conversation is potential contract or misrepresentation evidence.
Check: The letter states it supersedes prior oral and written discussions, and any promised terms that should survive (signing bonus, relocation) are written into it.

It can become one if drafted carelessly — annualized salary language, promised review dates, and duration-implying phrasing have all been treated as implied-contract evidence. Per-pay-period figures, a clear at-will clause, and an integration clause keep it an offer.
State it per pay period with the annualized figure as context. Some courts have read bare annual salaries as implying a one-year term.
In several states, yes, with hard deadlines — Massachusetts (with the offer or 10 business days pre-start), Illinois (14 days to review), Colorado (separate advance notice), Washington (by acceptance). Late disclosure can void the covenant.
Usually, but candidates who quit jobs or relocated in reliance have won promissory estoppel claims, and background-check rescissions require the FCRA adverse-action process. Resolve contingencies fast and get advice before pulling an accepted offer.
Background check (with FCRA standalone disclosure), I-9 work authorization, and any reference, license, or degree verification the role requires — stated expressly.
