Writing an Offer Letter That Does Not Create Obligations You Did Not Intend

An offer letter is a short document that occasionally turns out to be a contract. Most of the risk comes from ordinary phrasing nobody reviewed, written by someone trying to sound welcoming.

What belongs in it

Job title and who the role reports to
Employment status — full or part time, exempt or non-exempt
Start date
Compensation, expressed per pay period or per hour, not as an annual figure alone
Bonus or commission, with the plan referenced and its discretionary or formula basis stated
Benefits, summarised, with eligibility dates and a note that plan documents govern
Paid time off, referencing the policy rather than restating it
Work location and arrangement, specifically
Contingencies — background check, reference check, I-9 verification, drug screening where lawful and applicable
At-will statement
An acceptance deadline
Signature blocks

The phrasing that creates problems

Annual salary stated alone. "$90,000 per year" has been argued to imply a one-year term. Safer: "$3,461.54 per bi-weekly pay period, which annualises to $90,000."

"Permanent position." Says the opposite of at-will. Use "regular, full-time."

Guaranteed bonuses. "You will receive a $10,000 bonus in December" is a commitment. If it is discretionary, say so, and state whether employment on the payout date is required.

Promises about the future. "You will be promoted after a year," "your salary will be reviewed and increased," "this role will grow into a management position." Describe the review cycle, not the outcome.

"Probationary period." In some states this can imply that employment becomes something other than at-will once it ends. If you use an introductory period, state explicitly that it does not change at-will status.

Progressive discipline described as a sequence. Belongs in a handbook with appropriate disclaimers, not in an offer letter, and never as steps that will be followed.

Warm, open-ended reassurance. "We see you here for a long time," "job security," "as long as you want." Well-meant, and quotable later.

At-will language

Include a clear statement, and make it consistent with everything else in the letter.

A common formulation states that employment is at-will and may be ended by either party at any time, with or without cause or notice; that the letter is not a contract of employment for any specific period; and that only a named officer may alter at-will status, in a signed writing.

Then check that no other sentence in the letter contradicts it. Contradiction is where the exposure actually sits. See at-will employment explained.

State the contingencies before they resign

Anything the offer depends on goes in writing, clearly, before the candidate hands in notice:

Satisfactory background check
Reference verification
Proof of work authorisation and I-9 completion
Any required licence or certification
Drug screening, where lawful and applicable for the role

A candidate who resigns and then fails a contingency they were never told about is a serious problem — practically, reputationally, and in some circumstances legally.

Background checks are separately regulated. The FCRA requires standalone disclosure and written authorisation before a check, and a specific pre-adverse and adverse action process if the result affects the decision. Many jurisdictions also restrict when criminal history may be considered. See background checks and the FCRA.

Restrictive covenants

If the role involves a non-compete, non-solicitation, confidentiality agreement, or IP assignment, send those with the offer, not on the first day.

Presenting restrictive agreements after someone has resigned is poor practice, damages the relationship immediately, and in some states raises questions about consideration and enforceability.

Non-compete enforceability varies sharply by state — some restrict or prohibit them for many categories of worker, others enforce them broadly. Take state-specific advice rather than using one template nationally.

Practical points

Set a deadline of a few business days. Twenty-four hours is pressure and reads badly. A week invites a counter-offer to mature.

Send it promptly. Momentum between verbal offer and written letter matters, and delays are where candidates cool. See why candidates drop out at the final stage.

Attach the plan documents rather than describing benefits loosely. A letter that summarises a health plan inaccurately creates an expectation you then have to correct.

Have the manager make the verbal offer, with the letter following the same day.

Keep it to one or two pages. Detail belongs in the handbook and plan documents, referenced rather than restated — so that when a policy changes, the letter has not frozen an old version in place.

Multi-state

If you hire across states, the template needs state-specific review rather than one national version.

Differences that matter include restrictive covenant enforceability, notice requirements, wage statement and pay-transparency obligations, and mandatory notices that must accompany an offer or first day of employment in some states.
