The Governor says that many public employees don't opt out of unions because of fear of intimidation or harassment. I'm not convinced that's true--more likely it's concerns about being ostracized. I don't opt out because "opting out" means I'd still pay 100% of union dues and would get only about 15% returned to me, and I wouldn't be allowed to vote on my own freakin' contract since I wouldn't be a "full" union member.
Give me the opportunity to opt out completely, and I would. THAT might make the CTA more responsive to me, instead of the current situation where they take my money and run.
