Examples of employee warning forms are available at TidyForm.com and Entrepreneur.com. Both sites offer forms that can be downloaded or printed and are free to use.
Employee warning forms are used to write up employees who have violated company policy. The form usually contains a description of the nature of the infraction, as well as the type of warning. There is also space for both the employee and the manager to sign the form and authorize that they have seen it. The form may also include space for the employee to record his side of the infraction or write a plan for improvement.
