Pros
Good Job security Benefits were nice Plant personnel were polite for the most part Cheap cost of living, that's more the town than the company though
Cons
Lots of calls in the middle of the night, many requiring you to come in to the plant Overnight and weekend experiments are not uncommon; I've put in 24+ hour days before Corporate and plant can be very disjointed which creates a lot of communication and priority issues. Also, if you want something technically challenging or really get to use your engineering background, unfortunately this is not the position for you. 3M tends to put all the creative problem solving on the graduate degree holding corporate scientists in St. Paul. In a plant setting they essentially just want to see cost savings results
