Under California workers' compensation, which body system injury typically qualifies for a vocational rehabilitation benefit?

Explanation

The Supplemental Job Displacement Benefit under Labor Code §4658.7 turns on outcome rather than body part: it issues when the injury leaves permanent partial disability and the employer does not offer regular, modified, or alternative work the employee can do. (a) sets a treatment threshold — most injuries needing several visits resolve with no permanent disability and no voucher. (b) and (c) pick catastrophic injuries that certainly qualify, but they state the rule far too narrowly; a shoulder or back injury that ends a roofer's usual work qualifies just as well.
