first let me make clear that when i talk about tenure, i'm applying this to tenure of college professors NOT about tenure involving high school teachers or any teachers in schools.  i won't go in that direction because i don't know much at all about how tenure in a grade school or a high school works. saying that, i believe that giving tenure to a college professor is just plain wrong. by tenure i mean that once a professor has a certain amount of experience, they are essentially safe...it's almost impossible to fire them.

This kind of tenure is controversial; while it protects college professors from unfair dismissal, some critics argue it can limit their freedom to pursue unconventional topics and research. Furthermore, many argue that tenure is not applied fairly and can lead to unnecessary job protections and overly expensive legal battles. While I personally believe that tenure serves a useful purpose, both protecting college professors' freedom of expression, and providing stability in an academic position, I do believe that it needs to be regulated to ensure it is not misused. For example, some universities set certain guidelines, requiring professors to receive good evaluations, fulfill specific course and research responsibilities and make periodic reviews to maintain the tenure status.
