Do not file a valid Workers Compensation claim in California. Does not matter that you have a valid injury verified by lots of doctors. You will be black-listed nationwide. Employment-reference companies will distribute that you filed a claim for medical-benefits against a fellow-employer. No company will hire you nationwide. Every company today gets an employment reference report before hiring anyone. This black-listing is done in secret over the Internet with the full knowledge of the State of California government. Do not believe promises of claim confidentiality or privacy of medical-records. The California government is wholly corrupt. You will get no help from the Courts. The Courts always side with the California government.
