What Belongs in an Employee Handbook

No statute requires an employee handbook — and yet it appears in nearly every employment case, cited by whichever side it helps. Done well, it's a stack of defenses: the distributed harassment complaint procedure behind the Faragher-Ellerth defense from the investigations guide, the FLSA safe-harbor policy from the salary deductions guide, the acknowledged policy every termination points to. Done carelessly, it's the plaintiff's contract: promised procedures, guaranteed reviews, 'termination only for cause.' The organizing principle: every sentence either creates a defense, satisfies a requirement, or creates an obligation — know which, sentence by sentence.

Anything that reads as a promise: guaranteed progressive discipline ("employees will receive a verbal warning, then…"), probationary periods that imply post-probation security, promised annual raises or reviews, severance formulas (which become enforceable severance obligations), and "permanent employee" as a category. Also out: policies you don't enforce (an unenforced policy is comparator evidence against you), operational detail that changes monthly (put procedures in linked documents the handbook references), and — per the NLRB guide — the overbroad confidentiality, civility and social-media rules that violate federal labor law even in non-union shops.

Multi-state employers need the two-layer build: a national core written to the strictest common denominator, plus state addenda carrying what can't be national — the design detailed in the addenda guide. Version-control the document (effective dates on every page), collect dated acknowledgments at hire and at each major revision into the personnel file from the day-one process, and put one named owner on the annual review. A handbook nobody owns drifts — and drifts into whichever obligation a court finds first.
