Pros
Everyone gets benefits. This was before the ACA, so I don't know how this may have changed. The work environment is certainly fun if you're into drum circles. Pay is decent considering they'll hire 90% of people who walk through the door - IF you meet fundraising quotas.
Cons
Like any sales job, there is a quota. This is strictly enforced, but that it all laid out for you ahead of time. If you can walk door to door and get people to give you money on a regular basis, you'll be fine. There is also a very political tint to everything you'll do. It's a progressive company, so politics and policies are as well. If it comes up, and you end up saying something conservative, you will get funny looks and probably pushed out the door through passive aggression or subtle hints.
