Which of the following are covered by the Federal Employers' Liability Act (FELA)?

The Federal Employers' Liability Act (FELA) specifically covers employees of interstate railroads. This legislation was established to provide a legal remedy for railroad workers who are injured on the job due to the negligence of their employers. The act recognizes the unique nature of rail transport and the risks associated with it, granting railroad workers certain rights that are not available under other worker's compensation laws.

In contrast, the other options pertain to different sectors. Employees of local public transit are typically covered by state workers' compensation laws rather than FELA. Similarly, employees in state-funded construction and workers in non-union businesses do not fall under the purview of FELA, as this act is tailored specifically to railroads engaged in interstate commerce. Therefore, the only group clearly covered by FELA is employees of interstate railroads, which correctly identifies the focus and scope of this federal legislation.
