If you didn't HAVE to join a teacher's union, well, then I would be fine with it. But as that is not the case in good ol' MA, I really have a low opinion of them.
You don't have to join one, MQuinn.
ROTC instructor in "hot water" for refusing to pay dues, because he believed that his position was not classified amongst "classroom teachers"
http://www.telegram.com/article/20100611/NEWS/100619956/1116He was not a member of the Union but because of the Union's existence "he benefited from them" and "had" to pay. He was actually suspended upon Union request for a time, but was not fired. This was not because he wasn't a dues paying member, rather because being ROTC put him in a special category.
You are right you do not have to join a teacher's union, that is if you do not wish to be a teacher: “At the end of the day, there's a strong rationale that (Maj. Godin) and the other ROTC instructors should not be subject to these rules."
Rules refering to of course, the reasioning that they have to pay because their employment is benefited from the existence of the Union.
