On the first day of the employee, it is recommended that the employee sign, in addition to his contract, the secrets of the personnel, so that both parties are protected by law. The information on this page is intended to provide general information, not to provide legal advice or advice. Please contact your lawyer for advice on specific legal matters. California law defines the ownership of trade secrets. California is unique in that its laws explicitly state that the employer has business secrets established by an employee. ( Cal. Labour Code § 2860). However, an employer in California would not have established trade secrets without the use of material used in an employee`s time. .
