Pros
Witness the masterful art of people tricking themselves into believing they are not hypocrites. Also, the training can be alright.
Cons
Low wages, virtually no respect of employees' wellbeing, and you will be chastised if you don't drink the cool-aid. This organization is a cult. YOU WILL NOT BE ABLE TO AFFORD WORKING HERE IF YOU AREN'T ALREADY WEALTHY. They pay is greatly reduced because they will make you pay for everything. Think of a multi-level marketing scheme disguised as a progressive movement. TPIN will oppress you with the same tactics they claim to fight against. For the love of god, work somewhere else. Especially if you're driven by progressive values. If you are working there right now, please quit. Quit right now. Don't put in your two weeks in. Don't buy into the idea that you need to have a job to find a job. Just quit. Also, convince your co-workers to quit. I think that's the best way to show TPIN what real organizing looks like.
