In fact, the NEA teachers objected to non union people (most of us adult education folks were not teachers by trade) even teaching in the class rooms at night.
And where I live, first year teachers know better than to join the NEA. Those that want to join wait until they have their first year under their belt because if they join the NEA they can be sure that their contract won't be renewed.
As far as taking it out of your check...you opt to do that, it's not mandatory anywhere. Here, most teachers don't because they don't want to advertise that they are members.
I guess it all evens out, huh?

, but I do know that I chose a profession which I'm never going to get rich because I like the idea of dedicating my professional life to helping others. And, I don't think that's particularly rare. Of course, if students really were consumers, I'd be rolling in it! You should see my waiting list and course evals- I'd be off to WDW every weekend on a private jet.
