1. Tenure is there because parents are idiots. I fully support removing tenure in favor of a more fluid and workable teacher's bill of rights, but without the union, teachers would literally become babysitters and not figuratively. 95% of parents don't keep track of their students, as long as the students comes home without bruises and passes classes, they don't care. But 5% of parents seem to think that they need to start telling teachers what books they can and can't teach, what grades their children should be getting etc... In fact your first statement does even make sense, by getting rid of bad teachers, good teachers have an easier life? Except for the fact that bad teachers don't affect good teachers, they only affect the students.
So what about those parents who want to tell teachers what to do? Don't listen to them.

Yes, getting rid of bad teachers, who teach students poorly, makes things easier for other teachers who don't have to deal with poorly taught students in other grades or classes.

There is no way to judge how good a teacher is quantitatively to a precise measurement.
It doesn't have to be perfect. But using student test grades (and scaling AP class grades as appropriate) is a lot better than the current union endorsed system.

That makes no sense, and doesn't even hold up to the slightest scrutiny.
It doesn't?

The public perception of police and firefighters is that they face dangers hardly anyone else does. That they sacrifice a lot for modest wages. So when the governor doesn't go after their unions he doesn't appear stingy with 'heroes', and by comparison he appears more reasonable when he tries to cut the other unions.

I don't really mind our governor going after the public sector unions, but it bothers me that everyone thinks it's fine to attack the girls (teachers) and save the plums for the boys (police and firefighters). Seems like some sort of reflexive sexist bullhockey. Your thoughtless response just reinforces that impression.
Oh, and prison guards aren't mostly men?

You accuse me of sexism while generalizing all teachers as women, and all police as men?

You assume I don't want police unions busted up simply because I offered a reason why they weren't included?

But why bother about all that when you can accuse me of sexism?
