Pros
Production workers paid very well and because of some the remote locations could be a good job for office and supporting staff also. In some cases it is the one of the few or only major employer to make a decent wage.
Cons
The company feels they are the best thing there is and expects all from their employees making work your life. Benefits are mediocre. Pay even with the bonus figured in is very low for highly skilled and back office staff. Backstabbing is common and being in the wrong clique will likely mean no advancement. When doing research be aware that most of the information is based on Ken Iverson's Nucor. That Nucor no longer exists. Open communication is gone, employee empowerment is fading quickly. The new management being put in place are more concerned about their next advancement than taking care of the employees under them. You can see this by their increase in employee turn-over especially in non-production positions.
