Those are things I care about and do not want to give away for a union to decide for me or to have power over me. And some things just piss me off. In NY you are forced to pay unions dues just to be a teacher. It does not matter of you do want to participate or not. They have government like powers to charge you for something you do not want.
In addition, it's quite possible that in the future someone like me could not get my current job due to regulation. I know people in the same line of work as me that is forced to pay union dues because of his degree. The unions associated with the undergrad course he took forced him to pay union dues unless he can prove his current job does not relate to his degree. This is just absurd but still happens. I'd rather not have other people have even more control over me, no matter how much the word "democratic" is added to the argument
