In Hernandez v. Hillsides, Inc., S147552 (Aug. 3, 2009), the California Supreme Court unanimously held that the mere placement of a hidden video camera in an employee’s office could constitute an invasion of privacy, even if the camera was never actually used to record the employee. Under the specific facts of the case, however, the Court ultimately found no liability because the intrusion was relatively minor, limited and justified, but California employers should be aware that the use of hidden surveillance cameras without notice or warning in “semi-private” office space is likely to produce an actionable claim for invasion of privacy in many cases.
