Pros
Stuller has decent benefits and offers benefits of all kinds that you may want, the deductibles are a bit high though for such a larger company. The co-workers are pretty nice. When you pass someone in the hallway they are always willing to tell you hello. Nice, clean facility.
Cons
The cons would be, you do not have much freedom. I understand why they would be so strict, but I personally couldn't handle not being able to see outside/not being able to go outside during the day (unless you smoke, which I do not and you can't go otherwise). Also, I left Stuller for a much (MUCH!) smaller company who offers better benefit plans and it would have taken me 7 years to make $1 more an hour. I also feel that work gets thrown on you at a moment's notice with unrealistic deadlines. I also feel like there is too much emphasis on quantity, not quality. The specific department I was in timed every task we did and we were not allowed to talk while working and was told it was best not to go to the bathroom more than three times because it would mess up our "times."
