Pros
It is a job. I got hired between jobs and learned some good things, the company is disorganized, the managers are over worked and have too many people to manage. You have to truely make sure you get trained. They have strange payroll of bench time where you only get 60% of your pay on a stand by mode. They don't explain it very well, i think they don't on purpose, because it will scare everyone off. For a young guy it is a good way to get some real work experience in refinerys and power plants and can give some good things to put on a resume.
Cons
no communication. no communication, poor training, no planning for training, a lot of sitting around, then your gone for 3 days. They should have a outlined training program or at least of list of objectives a new guys is supposed to make sure he accomplishes. I had to look and ask and poke and prod and sneak and do it on my own.
