Pros
Great content. You feel like you're working for something you believe in. There are some great people there. They also have pretty good professional development opportunities.
Cons
Aside from low pay and not a lot of room for upward mobility, I've found my particular department (they're all different) to be a problem. It was a downright misogynist environment. It was like a bad, manipulative relationship with my boss and coworker that was allowed to exist. I was consistently bullied, perhaps because I was the only woman in my department. I worked there for 5.5 years because, in this field, there is nowhere else to go in the state. I would come home and feel raw. I cried most nights. Although there are lots of long-term, happy employees, it's a big place and I do believe the morale is consistently low throughout OPB. They do everything they can to not show any gratitude or appreciation for their talent. This place is absolutely ridiculous. I now happily work somewhere else and make way more money albeit in a different field. (By the way, they charge 75 cents for a K cup of black coffee and they don't offer cream or sugar. The coffee thing is superfluous but it's a microcosm of the experience.).
