Did you work at Gasper Marble and Tile?
Today, most new cases of silicosis in the US occur in shops where quartz and other engineered stone get cut. Workers who cut, ground or polished slabs for Gasper Marble and Tile in Sun Valley may have two claims: workers' comp via the employer's insurance, and the right to sue the companies that made the stone.
Two ways to claim in California
Workers' comp claims in California
- to file for workers' comp, from when it disabled you and you knew work caused it
- 1 year
- to send your employer notice in writing
- 30 days
The Department of Industrial Relations, Division of Workers' Compensation is where you file a workers' comp claim in California (official site).
Written notice to your employer is due within 30 days, and your filing deadline is one year past the injury date. With silicosis, that date is the day the illness first disabled you and you knew your job caused it, or should have. (California Labor Code §5400, §5405 and §5412)
A lawsuit against the manufacturers
A suit aimed at whoever made the stone or the equipment counts as a different claim, with a deadline all its own. How silicosis lawsuits work
Can't tell which company made your stone or your equipment? Labels on slabs or tools, along with pay stubs and job photos, can help a lawyer figure it out.
