Pros
Guaranteed 40 hours a week, cool coworkers mostly, no experience needed to be an Assembler I. Generally you're supposed to work four, ten hour shifts.
Cons
Poor raises, raises are also pro rated so expect your first one to be nearly worthless. Upper lower management at my location treats employees like metrics, and showed quite a bit of favoritism. They preach safety like it's extremely important (and it is), then push super hard for you to hit production numbers and cause people to make very unnecessary abnormal mistakes, which is a very big problem when making explosives. Management also receives monthly bonuses for hitting metrics, which means you're always gonna be pressured to hit them, even if it's not safe. All the while saying you need to be safe and pressing hard for numbers.
