Pros
The variety of job activities is interesting. You'll never have the same day twice. Boredom is not something that will occur while you're working. Shift work can be nice, depending on the schedule. 4 days on, 4 days off isn't too shabby. The pay is good, if you're production. The pay is decent if you're a skilled trade. Most of the people on the floor are good to work with, attitudes towards each other are good.
Cons
The pay isn't great if you're a skilled trade. The 4 on/ 4 off schedule doesn't include any extra days you may be randomly assigned to work. It also only occurs when manning is full for that position, which based on the first con can be a rare occurrence. There are definite instances of favoritism among advancement opportunities. The locations of a majority of the divisions is not good. Most people commute an hour each way to get away from the location the mill is built in. Vacation policy is poor, 2 weeks for ten years, then a third week until 15 years. Medical insurance is good if you're really sick, or really healthy. Co-pay is high (30%) although the premiums are fairly low.
