Nobody is safe. The company is grabbing as much cash as it can. Either to merge or buy eastern track or to look attractive to a potential buyer. They are picking places apart with little to no warning as I'm sure they don't want people getting "injured" right before they get layed off, hence why there is no warning. Unfortunately other Railroads are eyeing to do the same thing that UP has done. Lean line 2020.
