That's a slightly loaded question. I'm assuming you're alluding to difficulties schools have with firing burned out and ineffective teachers due to strict rules governing employee dismissal.
This is definitely an issue, however in my experience it is exaggerated by the media. Yes there are some who shouldn't be teaching, but they are far outnumbered by regular hard working people.
As for the other protections enjoyed by teachers i'd say they have a positive effect on employee mental health and would therefore have a positive flow on effect on student learning.
Actually I really wasn't trying to allude to anything. I am genuinely curious about how more teacher-friendly policies like those you mentioned affect students. Your last sentence answers my question.
