Pros
People here deeply care about the mission and you always feel like the work you're doing matters. You learn a lot about union history and culture. The staff has an inclusive, progressive worldview, and a bold plan for change. You also get paid $15 an hour (because of course the fight for $15 pays you appropriately) with health benefits.
Cons
They work you to the bone. Insane hours at every time of day and night for long stretches of time with only one day off that you're only sometimes able to take. To take on this job is to disapear into a hole of nothing but it. Burnout rates are very high, and it takes a very special kind of person to last long here. I'm not recommending this because you need to be the kind of person who will go despite someone recommending you not to in order to make it.
