Yes, the union was the thing I disliked most about teaching. Don't want to open up that subject here, though. In Arizona, a right to work state, I didn't have to join. No so, in MA. Of course, I'm an anomaly. I am all for merit pay, and in fact, was part of a state initiative that provided merit pay in Arizona. It provided a way for me to earn a lot more money at a time when I really needed to, as well as more professional development. I later did the National Board for Professional Teaching Standards certification during my last 10 years of teaching and I was able to use the extra salary the state of Massachusetts paid me for this, to pay for my son's college education. I don't know why teachers feel it's "bad" to earn more money for improving your skills and doing more work. I worked hard for that money and I think skills I gained benefited my students. Part of the reason I like doing fee for service work in my new field is that I am in total control of how much I make, and it makes me plan thoughtfully about how much I want to work, in order to meet my productivity requirements.
