Regardless of who was at fault for the injury, your friend would be entitled to file a workers compensation claim given that the injury occurred within the course and scope of employment.
As far as harassment and or possible termination, it is unlawful for an employer to retaliate against an employee for having filed a workers compensation claim and/or because of a disability or medical condition regardless of how the injury occurred. If your friend is concerned that he or she may be terminated I would advise him or her to file a complaint of discrimination with the California Department of Fair Employment and Housing. If you require or would like further informatio please let me know. Stephan Math Esq, smesq1@aol.com
