California’s statute forbidding retaliation against employee whistleblowers protects an employee who discloses to supervisors or public prosecutors or regulators information about what he believes are his employer’s violations of law–even if the recipient of the information is already aware of the reported violations. Section 1102.5 protects “disclosures,” a term broad enough to encompass emphasizing already known facts. The term “disclosure” may reasonably encompass an employee’s report or complaint that calls attention to a legal violation or potential violation in the workplace. The employee is protected even when he “discloses” the violation to the person allegedly committing the violation.
