All PSR has really done is accelerate a trend that was already well under way at UP. A toxic c—tail of nepotism, incompetent leadership at every level, high turnover, below average pay for the hours spent on the job, and unions that do nothing for their members or the business at large all but guaranteed that UP would tilt into decline well before PSR came into the picture.
PSR is either a last-ditch attempt to reform and modernize the railroad to make it more sustainable and flexible (although I don't see how), or a strategy for pumping all of the value out of the railroad to the last drop before leaving it in a shambles. In practice it looks more like the latter.
If you can get out, get out. Things will only get worse for those who aren't compensated in company stock. Even if PSR reaches all of its goals and they get to g55, UP will still be a miserable place to work for most people.
Merry Christmas and Happy New Year. May you all fare well in 2020.
