An Upjohn Warning refers to language contained in Upjohn Co. v. United States, 449 US 383 (1981), which provided greater protections to corporations with respect to attorney client privilege in conducting internal interviews.  Essentially, the Upjohn Warnings tell the employee that the attorney that is conducting the interview represents the employer and not the employee; that there is no attorney client privilege between the attorney and the employee; and that the company has the right to either disclose the contents of the communication or assert the attorney client privilege with respect to the communication between the attorney and the employee.  The Upjohn Warning acts as a corporate Miranda Warning.
