About This Template
Employment documents govern the relationship between a company and its workers, from offer letters and employment agreements through handbooks, performance reviews, and separations. Done right, they set clear expectations, protect against wrongful termination and discrimination claims, and give both sides a record to rely on. Done poorly, they invite lawsuits, agency complaints, and costly disputes.
