Four pillars of workplace injury law.

Most injured workers navigate more than one body of law at once. A single shoulder injury on a construction site can involve a workers compensation claim, a third-party suit against the scaffold company, an OSHA complaint against the general contractor, and eventually a permanent partial disability rating. Each pillar below covers one piece of that puzzle, with plain-English explanations and state-by-state notes where they matter.

Start with the area that matches your situation, or read through all four to understand how they interact. Every guide links to relevant statutes, regulations, and recent appellate decisions that shape how the rules are actually applied in practice.
