Pros
The pay is good. The benefits are good as well but seem like they may be more expensive. UP offers a challenging work environment in a good way. Perfect place to work for someone who gets bored with their job because portions of it will continually change and you can always just bid somewhere else and do something different.
Cons
They preach safety is the key to success. I believe this too, but it seems we are way to quick to terminate people over smaller things, then when something more severe happens to a person higher up in the company... It gets swept under the rug. We are starting a new process to educate and use others mistakes and experiences to educate everyone else. Being union is a good thing because they have fought for what we have now, but they have been deemed pretty worthless here as of late. Seems like a waste of dues. But!! That's all part of the game.
