Federal authorities say Union Pacific retaliated against three employees who raised safety concerns, so the railroad should pay $615,215 in fines and compensation.
The Occupational Safety and Health Administration said last week that it found evidence the Omaha, Neb.-based railroad violated the rights of two conductors based in Kansas City, Mo., and an engineer based in Tucson.
Two of the employees were fired and one was suspended five days after reporting workplace safety issues or work-related injuries.
