Give Sam a call and all your questions can be answered.
Don't get confused. It is "possible" to get back all your union dues, but not likely (certain religious beliefs, etc.). They are entitled to take out union dues for union work. Doesn't matter if you are a member or "fair share". It is only the money for political work that you can object to and get back. Federal law says they have to give you back your money if you object to them using it for political work, but only what they spend on political work.
When I started this, I talked to Sam in Salem, sent one fax, and some time latter got a check. The next January I got a thick envelope telling me of the wonderful things the union does for me and how ungrateful I was, but if I wanted to continue being fair share and get a refund for the political money, I needed to send them another letter. Every January I send them my letter. "Please, Please give me my money back!"
