Employment Law Questions? Ask an Employment Lawyer.
There are sometimes state laws (and federal laws, depending on the legal violation or law impacted) which prevents employers from firing employees who file legal complaints against them. The LA legislature discusses those laws, normally referred to as "whistleblower laws" or protections, here and by the Dept. of Labor here. Employers who violate such laws may be sued by employees for any damages, such as lost wages, lost jobs, and other costs employees may have suffered for any illegal termination. You should speak to an attorney in your state, quickly, as the time to file suit can quickly run out, to obtain assistance if you wish to pursue a case.
