We don't know how the Supreme Court will decide the issue of teachers forced to pay dues.  According to news reports, the Court is ready to scrap it:

During more than an hour of oral arguments on Monday, the high court's conservative justices seemed likely to side with a group of California teachers who say those mandatory fees violate the free-speech rights of workers who disagree with a union's positions.

Again, oral arguments do not translate into a ruling, as we remember from all of those predictions about Obamacare.  

Beyond constitutional issues, the problem is that the public-sector unions are cash registers for the Democratic Party.   

For example, the National Education Association donated 99% to Democrats in 2014.  Are you telling me that 99% of educators voted Democrat?   

The American Federation of Teachers donated 100% to Democrats.   

It was about the same in 2012, when the aforementioned NEA gave 96% to Democrats.   

We don't know for sure how teachers voted in 2014 or 2012.  Let's assume that most of them voted Democrat.  However, my guess is that it was closer to 60-40% than 99-1%.    

Therefore, it's easy to understand why so many teachers do not want to be forced to pay dues that only support one political party or won't represent the wishes of its members.
