Lots of ability to move into different departments or move up if you are a quick learner. Long term employees are respected and paid well. Generous ownership/ management. Pizzas parties, profit sharing, breakfasts, steak or burger bbqs are all very common.
Cons
Filthy, dangerous work environment. Incredibly loud at all times. Brutally hot in the summer months. Shift work. Virtually every department is dangerous and people are hurt frequently.
