(A person has a legally protected privacy interest in a particular class of information only to the extent that “well-established social norms” recognize that type of information as sensitive and define the need for individual control over it.)

TBG Ins. Services Corp. v. Super. Ct., 96 Cal. App. 4th 443, 452 (2002)

(employee was issued a home computer to use for business purposes and he signed a consent form acknowledging his employer’s right to monitor his use of the computer. The employee was terminated for using his office computer to access pornographic sites. The employee sued for wrongful termination and, in discovery, the employer sought production of the home computer. The appellate court found that he had no expectation of privacy: “[Employer’s] advance notice to [Employee] gave [Employee] the opportunity to consent to or reject the very thing that he now complains about, and that notice, combined with his written consent to the policy, defeats his claim that he had a reasonable expectation of privacy.” )
