Teachers' responsibility

  There are many problems in a school, such as bulling and relationship with others.  Teachers' quality and responsibility are one of them.  I think teachers should be evaluated, and depending on the result, their salary should be fluctuated.
  First, teachers are so secure job that they tend to be lazy in classes.  In Japan, a teacher is civil servant, and once they get their job, their whole life would be guaranteed.  Because of this, some teachers are not enthusiastic and their class is not interesting. 
 Second, students' or their parents' opinions should be reflected.  The job is so socialist that there are less competitions between teachers to get high estimate.  It should be more democratic and assessments should be reflected immidiately.
In conclusion, if these problems are solved, the working environment will be better and students can get high quality education.
