Anatomy of a clean offer letter
An offer letter is not the employment contract — it's the trust-building handshake before it. A good offer letter is short, complete, and unsurprising. Every figure should match what the candidate has been verbally told, every contingency should be explicit, and the legal language should be jurisdiction-correct (US at-will is fundamentally different from UK or EU contractual employment).
What every offer letter must include
- Position. Job title, reporting line, location (specify hybrid or remote terms exactly), and start date.
- Compensation. Base salary, bonus structure (with target and basis of payment), and equity (with vesting and approval status).
- Benefits. A high-level summary — medical, retirement, leave. Refer to the full benefits handbook rather than restating it all here.
- Contingencies. Background check, right-to-work, references, satisfactory medical (where lawful), drug test (where lawful and standard for the role).
- Terms. Notice period, probationary period (UK / EU), at-will language (US).
- Acceptance window. A specific date by which the offer expires — both as an action-forcing function for the candidate and to protect the company against open offers drifting.
The legal reminder. This generator produces a starting-point template, not a contract. Always have your offer letter reviewed by qualified employment counsel in your jurisdiction (especially for senior, executive, or international hires).
US vs UK offer letters — the differences that matter
- Employment basis. US offers are at-will; UK offers must be supported by a written statement of particulars (delivered no later than the start date).
- Right to work. US uses Form I-9; UK requires Home Office prescribed checks.
- Notice period. US has no statutory notice (other than contracts); UK has both statutory and contractual notice that grows with service length.
- Probation. Often informal in the US; standard 3-6 months in the UK with reduced notice during the period.
- Holiday. US has no statutory minimum; UK has 28 days statutory minimum (5.6 weeks, may include public holidays).
