A company pays into Workers Comp based upon the claims made against it, this is why the coffee company fought this guy's claims.
Therefore, it isn't all bad that IA's can collect Work Comp, because now the company has lost one economic incentive to hire the undocumented worker.
My understanding is tht WC is charged to employers by the state at a rate for a given job. Employers are charged much more for drilling & blating than clerical work, and "benefits" are paid from an industry-wide pool. Having more incidents, all employers, not just the one in question, have to pay more. (Purposely skipped the EMR talk).
