The unadulterated toxic rot that is Union Pacific Railroad has been covered in detail on this forum and elsewhere, with the capstone being that UPRR is now rated as the worst company to work for in the United States. Let that sink in. Fast food restaurants and grocery store chains are better places to work than UPRR.
This opens up some important questions. Since UP2020/PSR are strategies, and strategies are employed to reach specific goals, what are those end goals? What does the railroad look like in one/five/ten years? Will there even be a UPRR? What is the end game? Do they just want to drive everyone insane who they can't furlough or who won't quit?
