Pros
The people, the people, the people! The Seattle office grew significantly while I was there and everyone that came though those doors was passionate about human rights. The local leadership is excellent. There are a lot of leadership opportunities within the local office. Benefits(health insurance, PTO, Sick time). There is a bonus structure to reward success. I was able to even attend a training in DC paid for by the company. Best of all, you get to make a difference!
Cons
A lot of attrition, canvassing is hard work and its easy to get burnt out. The pay, even for leadership wasn't low but wasn't exceptional either. There is another group in Seattle that pays significantly more. With that said, the Seattle TOT office just bumped their pay for canvassers from $15 to $17/hour plus bonuses. There are few leadership opportunities beyond canvass director if you are tied down to Seattle. (Better if you are single or don't have a family.)
