Federal programs that may apply
The Missouri program covers most private-sector workers. Three federal programs run in parallel for specific worker categories:
- FECA — Federal Employees’ Compensation Act. Covers civilian federal employees. Filed through the US DOL, Office of Workers’ Compensation Programs.
- LHWCA — Longshore and Harbor Workers’ Compensation Act. Covers maritime workers (longshoremen, shipbuilders, harbor workers) on navigable US waters.
- Jones Act — 46 U.S.C. § 30104. Covers seamen injured in the course of employment. Provides a negligence cause of action and maintenance and cure rights outside the state WC system.
