For a company that is supposed to be unconcerned with what is said about them on these and other websites, they sure are keeping close tabs on the commentary made there. While there were always questionable reviews being left in both places, they've gone into overdrive recently, with five-star reviews being left by people who have clearly never worked for UP or any other railroad.
All I can say to everyone is keep spreading the word about the special brand of toxicity, dysfunction, and nepotism that are the cornerstones of UP corporate culture. By getting the word out it may force some change for the better for those still working there.
