Mailing a reference check form is a more formal way of requesting information. Former employers are more inclined to give detailed responses when they have the ability to fill the reference out on their own time. The Reference Check Form asks questions regarding salary history, eligibility for rehire, and dates of employment. In addition it requests more in depth information about strengths and weaknesses and reasons that an employee may have decided to leave. By using an existing form you can aviod asking discriminatiry questions that may lead to costly legal disputes.
