Amtrak working conditions

I just read a series of interesting posts surrounding the run away freight on CSX. These posts highlighted some of the working conditions that railroaders worked under. They were very informative to me.

I was interested in the perspective of employees who worked for Amtrak. I have travled on most Amtrak trains and have observed a wide range in performance by amtrak employees. If possible, could any Amtrak employees respond?
