California Code, Labor Code - LAB § 1024.6

An employer may not discharge an employee or in any manner discriminate, retaliate, or take any adverse action against an employee because the employee updates or attempts to update his or her personal information based on a lawful change of name, social security number, or federal employment authorization document.  An employer's compliance with this section shall not serve as the basis for a claim of discrimination, including any disparate treatment claim.
