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.

I would agree with you that tenure is not a universally suitable model for all teachers, as not all educational environments require the same level of security or stability. However, college professors often have a greater degree of professional independence and autonomy, and are also typically contributing significant works of intellectual and scholarly property that benefit not just their particular institution, but higher education more broadly. As such, it could be argued that college professors are due the most protection in terms of ensuring their academic freedom, intellectual property rights and right to due process if dismissal is deemed necessary. 
I believe tenure is still a necessary component of higher education in order to ensure such academic freedom and stability, as opposed to the unpredictability that some schools or institutions may choose.
