If the Employee Disagrees

Regardless what form the documentation for disciplinary action takes, allow for employee comments and signature.

If the employee makes comments about changing or rectifying the behavior, you have documentation that the employee understood and accepted the discipline.

If the employee disagrees with the action, you have documentation that you participated in this process with the employee. Allow the employee to record his or her disagreement on the form, but also try to work with the employee to come to an understanding. Document that process as well.

If the employee refuses to sign the document, you at least have proof that the employee refused to participate in the process should the employee later challenge your actions. Note on the document that the employee refused to sign.
