A more thorough explanation:

The Federal Employees' Compensation Act (FECA) is a law that provides workers' compensation benefits to federal employees who are injured or become ill as a result of their job. This law covers a wide range of federal employees, including postal workers, military personnel, and civilian employees of the federal government.

Under FECA, federal employees who are injured or become ill as a result of their job are entitled to medical treatment, wage replacement, and other benefits. These benefits are designed to help injured workers recover from their injuries and return to work as soon as possible.

For example, if a postal worker is injured while delivering mail, they may be eligible for medical treatment, wage replacement, and other benefits under FECA. These benefits can help the worker recover from their injury and return to work.

Another example is a civilian employee of the federal government who develops an illness as a result of exposure to hazardous materials on the job. This employee may be eligible for medical treatment, wage replacement, and other benefits under FECA.
