Apparently, there are more than a few employers who are mining their email archives to search for email communications between employees and former employees and the attorneys representing them in claims against the employer. One judge in New York issued a ruling last year that such communications are not protected by attorney-client privilege. The case is Scott v. Beth Israel Medical Center, Inc. You can read the order here. We haven't researched whether any California cases are on point. We're just passing it along.
